Coursework: Projecting of regional electric fences. Vibrating for the configuration of the rose-by-line hedge Razorbka 4 options for the configuration of the hedge

The performance form for the flow and forecasted graph will be lost in the same way, as the value of the imovirn_snyh characteristics change proportionally.

In such a rank, we recognized the predicted pressure of the PS. Dal, vikoristovuchi "Rozrakhunok festo" can be recognized all the other characteristics.

It is necessary to brutalize the fact that the maximum effort has been established for everyone in the "framing of the hedge" in order to go more, they didn’t put it. it is not physically possible. It will be explained by the fact that when writing the programs "Rozrakhunok festi", the student's coefficient will be accepted 1.96. There are a lot of people who are happy with them.

Analysis of imovirnіsnyh characteristics

For the tribute from the "Rozrakhunka of the hedge", we recognize the active urge to guide us to the universities. Reactive pressure is significant for reactive pressure in the department at the KP in the skin university

As a result of the distribution of the necessary forecasts of the necessary characteristics, which are added to the Dodatka A. For newer projects, they will be deprived of predicted characteristics. The reactive efforts are insured on the basis of the formulas (2.6) and are transformed into the supplement of A.

3. Development of MOZHLIVIH VARIANTIV SCHEMES TA ЇX ANALIZ

Methods for the distribution and selection of the most economically prescriptive options for the electric grid given to the area. The options need to be grounded, given dignity and shortcomings, and converted to practical health. If all the stinks can be realized, then, vreshty-resht, there are two options, one of which is the least summarized in the line in one-liner, and the smallest one.

3.1 Development of flexible options for configuring electrical hedge and output of competitive building

Principles Induce the Heirloom

Electrical circuits are responsible for the use of vitrates. The electric net is guilty of the mother as well as the necessary economy and toughness. / 3, p. 37 /.

In the design practice to induce the rational configuration of the hemisphere, the cooking method should be used, but for the given development, there will be a number of options. Numerous options are not guilty but vypadkovy - leather primed on the principle of prompting the hem (radial hem, kiltseva, etc.) / 3, p. 37 /.

When developing the configuration of options in the hedge, the following is the principle:

    The supply of the 1st category of guilt will be taken care of by the power supply from two independent power supply systems, at least two lines and interruptions in the power supply are allowed for the period of automatic switching on, backup life. 1.2.1 / 3/3/3/3/3/3/3/3/3/3

    For those who live in the II category in a large number of vipads, they can also transfer food for two other lines, or according to Dvolantsyugovy lines.

    For an electric appliance of the III category, complete the harvest one line at a time.

    Vinyat of vortex streams of exertion in rosy framing

    Rowing of electrical framing to docillary health at the university

    In the case of the ringlets, one line of nominal springs is to blame.

    Stagnation of simple electrical circuits of rozpodilnyh attachments with a minimum amount of transformation.

    The option of a measure is guilty of transferring the necessary level of power supply

    Main lines may be in some cases with circular lines, but there is a great length of submarines in a single line; large numbers of high-quality and manual ones in case of operative victorian

    It is necessary to transfer the development of power supply lines at the points of accommodation

    The option of the electric circuit is guilty but technically good, that is, it is due to the transformers, because of the change of the lines on the line.

Development, adjustment and revision of options in the configuration of the mesh

The proportional indicators of the proponated options in the hemisphere have been added to B.

Respect: for robustness in robotized programs, letters of the designated PS are replaced with digital ones.

I will look at the development of the PS, their efforts have been propounded by the chotiri options for connecting to the VP.

The first option has three PSs to go to the TES according to the circular scheme. Quarter PS G (4) live as TES and URP. An outstanding option is the hope of all survivors, some of all PS in this option, there are two independent dzherela living. In addition, the scheme is handy for dispatching control (all substations are in transit, which are put into repairs and allowing quick reservations).

Malunok 1 - Option 1

For lowering the struma in the PA mode (when one of the main dylanoks is connected) in the rings of PS 1, 2, 3, the proponations of option 2, de PS 2 and 3 start in the circle, and PS 1 is grabbed along the Dvolantsyugovy VL. Malunok 2.

electric hemstitch for vitrat

Malunok 2 Option 2

For the hardening of the connection between the displayed centers of the harvesting, option 3 is set, in which PS 3 and 4 it is to live from TES and URP. Daniy is an option to act as the first two about the length of the overhead line, however, it is possible to improve the reliability of the power supply circuitry for the substation V (3). Malunok 3.

Figure 3 Option 3

At option No. 4, the most suitable resident of the PS 4, visions on the border of harvesting on Dvolantsyugovy VL from TES. In this vipad of the links between TES and URP, the mensh gave, however, the PS G (4) is right there from the other PS. Malunok 4.

Malunok 4 Option 4

For re-training, it is necessary to carry out the work according to the recommended options.

According to the formula of Ilarionov, it is significant to rationalize equal springs for all visible head-ends and radial overhead lines:

,(3.1)

de - dovzhina dilyanka, for which purpose the tension starts;

- the pressure of exertion, which is transmitted through the tsiy dilyantsi.

For vnnachennya springs in rings, it is necessary to make a rational spur on the head plates. For the sake of the flow of the most active strain on the head racks, at the same time, they will start to get started about the time spent on the racks. At the outrageous viglyad:

,(3.2)

,(3.3)

de P i - the maximum forecast is the pressure to supply i th university;

l i0`, l i0`` - more lines from i-th point of the hemline to the generalized end (0` or 0``) of the open-ended scheme for replacing the circlet in the case of the development at the point of life;

l 0`-0`` - the total amount of dinner of all dalyanoks of ring hedgehogs. / 4, z 110 /

In such a rank, we can accept the springs for turning us into diagrams of circuits, the development of various images in supplementary B.

The order of options is shown in table 3.1

Table 3.1 - Parameters of options in hedge

Behind the front bags, you can choose between options 1 and 2 for a closer look.

3.2 Detailed analysis of competitive building options

At a certain point, it is necessary to assess the number of possessions, as it is necessary for a reliable and efficient electrical supply: transformers, power transmission lines, the need for compensating attachments, power supply circuits. In addition, on this stage, assess the technical ability (docility) of the implementation of the proponated options.

Vibir of the bit and the exertion of compensating attachments

Compensation of reactive tautness - rectifying the flow to the balance of reactive tautness at the university of the electric power system by means of regulating the tension, and in the rosy framing, by means of reducing the energy consumption. Zdіysnyutsya z vikorystannyam compensating attachments. In order to meet the necessary pressure in the universities of the electrical system for living up the reactive effort, it is necessary to generate the need to generate the pressure for the necessary reserve. The generated reactive urge to store up with the reactive urge, which is rocked by the generators of power plants and the reactive urgency of compensating attachments, spaced out in the electric grid and in the power plants in a way that makes the electric power available.

Come to the substation for compensation of jet pressure to allow:

Entry

Electric power plant-tse installation, designed for the redevelopment and distribution of electrical energy. The building is stored with transformers, busbars and communication devices, as well as ancillary equipment: attachments for relay control and automation, virtual attachments. Power stations are intended for the connection of generators and those connected to power transmission lines, as well as for the connection of other parts of an electrical system.

Modern energy systems are stored in hundreds of interconnected elements, which can be poured one on one. The project is guilty of being carried out with the help of the main minds of the spilo robot elements, which is poured into the given part of the system. There are a number of design options for providing such benefits: reliability, economy, efficiency of operation, quality of energy and flexibility for future development.

In the course of the course design, one can bathe in the corystuvannya with pre-literature, GOSTs, single norms and enlarged indicators, tables.

At the head of the course design to drive practical engineering methods, the development of complex power supply with the equipment of power lines, production stations and other elements of electrical systems, as well as the need for further development of robotic systems. The particularity of the design of electrical systems and polyagons in a tight interconnection of technical and economic design. The vibe of the most dacha version of the electric power station is not carried out only by theoretical design, but on the basis of the new world.

1.1. Geographic development of Dzherela living "A" and 5 universities

Vibrating for configuring rose-based hems

Vibir of rational configuration of rosette hedge є one of the head meals, which can be seen on cob stages of the design. Vibir of the scheme is carried out on the basis of technical and economic presentation of a number of options. Possible options for determining the technical health of the skin from them according to the parameters of the main electrical equipment (darts, transformers, etc.)

The development of options needs to be fixed on the basis of the offensive principles:

a) the scheme is to blame for the possibility (grounded) of idle time and the transfer of electricity to the survivors is to blame for the shortest path, without the ringing of the need, without the loss of energy consumption.

b) the diagrams of electrical installations for lowering power stations are also guilty but simple (grounded), so that there is no need to reduce the cost of equipment and operation, as well as the need for work;

c) after the pragmatic power of the electric circuit with a minimal amount of transformation of the power, so that the need to reduce the need for transformers and autotransformers, as well as the need for power and power;

d) circuits of electrical circuits are responsible for ensuring the reliability and the need for electrical power supply, and not to allow overheating and overwhelming electrical cooling lines and processes (according to the strings in the time of day)

It is obvious that the PUE in case of the presence of conditions of I and II categories on the substation of the electric power supply from the least of the engineering system can be no less than two lines, we connect to the independent dzherel of the livelihood. For the urahuvannya vishche vikladenogo and with urahuvannya alternatives of qualities and indications of singing types of schemes, it is recommended to formulate in the first place the variants of schemes of hedge: radial, radial-magistral, simplest ring types.

2. ROSRAHUNOK І FORECASTING IMOVIRNіsny characteristics

For this distribution, the definition of the imovirnіny characteristics, necessary for the selection of the main possession of the project framing and the development of the wattlessness and energy, is carried out.

In addition to the current data, the information about the installed strain of the PS and the types of graphs on the basis of the characteristic features of the electric power supply is presented.

2.1 Procedure for developing imovirnіsnyh characteristics

The rozrakhunok of imovirnіsnyh characteristics is carried out with the help of the programs "Rozrakhunok of frizzy". The whole software complex will ask for the knowledge of the necessary indicators for the development. Stavlyaci in the quality of the outgoing dates are only the most active effort, the type of survivors and the percentage of expenses on the PS, we accept the necessary characteristics. Accepted types of power supply in Table 1.1.

In such a rank, we recognized the predicted pressure of the PS. Dal, vikoristovuchi "Rozrakhunok festo" can be recognized all the other characteristics.

It is necessary to brutalize the fact that the maximum effort has been established for everyone in the "framing of the hedge" in order to go more, they didn’t put it. it is not physically possible. It will be explained by the fact that when writing the programs "Rozrakhunok festi", the student's coefficient will be accepted 1.96. There are a lot of people who are happy with them.

Analysis of imovirnіsnyh characteristics

For the tribute from the "Rozrakhunka of the hedge", we recognize the active urge to guide us to the universities. Reactive pressure is significant for reactive pressure in the department at the KP in the skin university

As a result of the distribution of the necessary forecasts of the necessary characteristics, which are added to the Dodatka A. For newer projects, they will be deprived of predicted characteristics. The reactive efforts are insured on the basis of the formulas (2.6) and are transformed into the supplement of A.

3. Development of MOZHLIVIH VARIANTIV SCHEMES TA ЇX ANALIZ

Methods for the distribution and selection of the most economically prescriptive options for the electric grid given to the area. The options need to be grounded, given dignity and shortcomings, and converted to practical health. If all the stinks can be realized, then, vreshty-resht, there are two options, one of which is the least summarized in the line in one-liner, and the smallest one.

3.1 Development of flexible options for configuring electrical hedge and output of competitive building

Principles Induce the Heirloom

Electrical circuits are responsible for the use of vitrates. The electric net is guilty of the mother as well as the necessary economy and toughness. / 3, p. 37 /.

In the design practice to induce the rational configuration of the hemisphere, the cooking method should be used, but for the given development, there will be a number of options. Numerous options are not guilty but vypadkovy - leather primed on the principle of prompting the hem (radial hem, kiltseva, etc.) / 3, p. 37 /.

When developing the configuration of options in the hedge, the following is the principle:

1 Power supply of the 1st category of guilt will ensure that the power supply is not provided from two independent power supplies, at least two lines and interruptions in power supply are allowed to be deprived for the period of automatic 3 activation / backup. 1.28 /

2 For those who live in the II category in a large number of vipads, they also transfer food for two other

3 For an electric appliance of the III category, complete the harvest one line at a time.

4 Vinyatnye vorotnykh streams_ in the tightness

5 Distribution of electrical fittings for additional support at the university

6 In k_ltsevskaya hemlines, one r_ven of the nominal springs is guilty.

7 The stagnation of simple electrical circuits of rozpodilny annexes with a minimal amount of transformation.

8 Variant of a measure is guilty of transferring the necessary level of power supply

9 Main lines may be in some cases with rings, but there is a great length of submarines in a single line; large numbers of high-quality and manual ones in case of operative registration

10 It is necessary to transfer the distribution of power supply lines at the points of accommodation.

11 Variant of the electric line is guilty but technically good, that is, it is due to the transformers, because of the change of the lines on the line.

Development, adjustment and revision of options in the configuration of the mesh

The proportional indicators of the proponated options in the hemisphere have been added to B.

Respect: for robustness in robotized programs, letters of the designated PS are replaced with digital ones.

I will look at the development of the PS, their efforts have been propounded by the chotiri options for connecting to the VP.

The first option has three PSs to go to the TES according to the circular scheme. Quarter PS G (4) live as TES and URP. An outstanding option is the hope of all survivors, some of all PS in this option, there are two independent dzherela living. In addition, the scheme is handy for dispatching control (all substations are in transit, which are put into repairs and allowing quick reservations).

Malunok 1 - Option 1

For lowering the struma in the PA mode (when one of the main dylanoks is connected) in the rings of PS 1, 2, 3, the proponations of option 2, de PS 2 and 3 start in the circle, and PS 1 is grabbed along the Dvolantsyugovy VL. Malunok 2.

electric hemstitch for vitrat


Malunok 2 Option 2

For the hardening of the connection between the displayed centers of the harvesting, option 3 is set, in which PS 3 and 4 it is to live from TES and URP. Daniy is an option to act as the first two about the length of the overhead line, however, it is possible to improve the reliability of the power supply circuitry for the substation V (3). Malunok 3.

Figure 3 Option 3

At option No. 4, the most suitable resident of the PS 4, visions on the border of harvesting on Dvolantsyugovy VL from TES. In this vipad of the links between TES and URP, the mensh gave, however, the PS G (4) is right there from the other PS. Malunok 4.

Malunok 4 Option 4

For re-training, it is necessary to carry out the work according to the recommended options.

According to the formula of Ilarionov, it is significant to rationalize equal springs for all visible head-ends and radial overhead lines:

,(3.1)

de - dovzhina dilyanka, for which purpose the tension begins;

- the pressure of exertion, which is transmitted through the tsiy dilyantsi.

For vnnachennya springs in rings, it is necessary to make a rational spur on the head plates. For the sake of the flow of the most active strain on the head racks, at the same time, they will start to get started about the time spent on the racks. At the outrageous viglyad:


,(3.2)

,(3.3)

de P i - the maximum forecast is the pressure to supply i th university;

l i0`, l i0`` - more lines from i-th point of the hemline to the generalized end (0` or 0``) of the open-ended scheme for replacing the circlet in the case of the development at the point of life;

l 0`-0`` - the total amount of dinner of all dalyanoks of ring hedgehogs. / 4, z 110 /

In such a rank, we can accept the springs for turning us into diagrams of circuits, the development of various images in supplementary B.

The order of options is shown in table 3.1

Table 3.1 - Parameters of options in hedge

Behind the front bags, you can choose between options 1 and 2 for a closer look.

3.2 Detailed analysis of competitive building options

At a certain point, it is necessary to assess the number of possessions, as it is necessary for a reliable and efficient electrical supply: transformers, power transmission lines, the need for compensating attachments, power supply circuits. In addition, on this stage, assess the technical ability (docility) of the implementation of the proponated options.

Vibir of the bit and the exertion of compensating attachments

Compensation of reactive tautness - rectifying the flow to the balance of reactive tautness at the university of the electric power system by means of regulating the tension, and in the rosy framing, by means of reducing the energy consumption. Zdіysnyutsya z vikorystannyam compensating attachments. In order to meet the necessary pressure in the universities of the electrical system for living up the reactive effort, it is necessary to generate the need to generate the pressure for the necessary reserve. The generated reactive urge to store up with the reactive urge, which is rocked by the generators of power plants and the reactive urgency of compensating attachments, spaced out in the electric grid and in the power plants in a way that makes the electric power available.

Come to the substation for compensation of jet pressure to allow:

· Zmenshiti navantazhennya on transformer, zbіlshiti termіn їkh service;

· Zmenshiti navantazhennya on darts, cables, vicoristovuvati їkh menshy peretinu;

· Policies for the quality of electric power at electric power supplies;

· Zmenshiti navantazhennya on komutatsіynu equipment for rakhunok reduction of strumіv in lantsyugi;

· Reduce vitrati for electricity.

For the skin area taken PS in front of the front, the value of the KU force is determined by the formula:

,(3.4)


The maximum reactive pressure of the university is navantazhennya, МВАр;

The maximum active capacity of the university is to supply, MW;

The coefficient of reactive effort is initiated by the order of the Ministry of Industry and Trade No. 49 (for hemlines 6-10 kV = 0.4) / 8 /;

For two options in the grid of rosrakhunkov, the mating on all the links of the guidance is in table 3.3. For trivially let’s allow the strum to carry out a rewiring for the drain heating of the wires. So, if the strum in the line in the emergency mode is less, it is not trivially permissible, then if you give the dart you can vibrate for the given line.

Similarly, transformers are vibrated for all substations. The results of the induction of transformers are shown in Table 3.2.


Table 3.2 - Vibran power transformers for projected fences.

Vibir of optimal RP circuits at substations.

Schemes of the RU vishoi napruga.

Through a large number of substations, there is a transit of demand, so the optimal option for them is a scheme of mistooks with vimikachs in transformer stakes, with a non-automatic repair changeover from the side of the line.

The VN switchgear diagrams are based on the positions of the PS in the framing, on the other side of the fenestration, the number of inputs. Razrіznyayut such type of training for familiarity with the position in the netting of the other springs: vuzlovi , prohіdni, vіdgaluzhuvalnі and kіntsevі. Universities and transit stations є transit, there is a bit of an effort to be transmitted along the line, to pass through the busses of the transit stations.

In this course project, on all transit substations, the scheme "Mistok with vimikach in lantsyugi liniy" is stuck in order to ensure the greatest reliability of transit flows. For a dead-end substation, to live for the Dvolantsyugovy OHL, the scheme "two blocks of the line-transformer" is stuck with the obligatory connections of the AVR on the side of the LV. The given diagrams are displayed on the first arch of the graphic part.

4. VIBIR OF THE OPTIMAL OPTIMAL VARIANT OF THE ELECTRIC MEREZHI SCHEME

The meta given to the product is already included in the title. However, it should mean that the criterion for determining the options in the whole distribution will be economical. The price will be rooted for guided vitrates for the development of parts of the project diagrams.

4.1 Algorithm for the reduction of reduced vitrates

Induce vitrati and start with the formula (4.1)

de E - normative efficiency of capital investment, E = 0.1;

K - capital investment, necessary for the construction of the framing;

I - well-known exploitation vitrati.

Capital investment for the maintenance of the net is stored with the capital investment in the new lines and in the PS

, (4.2)

de K VL - capital investment for the construction of lines;

Before the PS - capital investment for the construction of the production station.

Vyhodyachi from the parameters, it can be seen that for a given specific vypadku it is necessary to vrahovuvati capital invested in VLEP's business.

Capital investments during the installation of the lines are stored from the vitrate for the pre-day robots and preparation of the route, the vitrate for the support, conduction, isolation and installation, for the transport, installation of the robot and

de - pitoma part of one kilometer of line.

Capital vitrates when equipped with a food station are stored from vitrates for the preparation of the territory, adding transformers, batteries and other possessions, vitrates for assembling robots, etc.

de - capital vitrati for the construction of outdoor switchgear;

Capital vitrati for the purchase and installation of transformers;

Potential part of vitrate at substation in fallowness of type GRP and U nom;

Capital vitrati for the purchase and installation of KU.

Capital investments begin for the enlarged indicators of the variability of the elements of the mesh. The total capital investment is brought up to the flow rate for an additional inflation rate for the period of 1991. For the specific realities of overhead lines for the current year, the rate of inflation for overhead lines in a given KP is k іnfVL = 250, and for elements of PS k іnfVL = 200.

Another important technical and economic indicator is the exploitation of vitrati (vitrati), which is necessary for the exploitation of an energetic possession of that net by stretching one rock:


de - vitrati for current repairs and exploitation, including preventive maintenance and testing, start according to (4.6)

Vitrati on amortization for analysis of the period of service (T sl = 20 years), formula (4.7)

Go to KU. So, as on all substations, capacitor banks are installed in or Static thyristor compensators (STC), then if the KU will be in charge of the offensive rank


, (4.12)

de - enter into active exertion in compensating annexes, in this drop - 0.003 kW / kvar.

Rivni PS springs do not appear in both options, so transformers, attachments, can compensate and lose in them if they are damaged, it is possible not to vrahovuvati (I will stink the same).

4.2 Competitive options

So, in some cases, there is one level of pressure, the transformers and the number of annexes, which will compensate for them, will be unimportant. In addition, PS G (4) live the same way in two options, but in some cases do not take care of it.

There will be only a few lines (additional supply and rerouting of the wire) and additional attachments to live PS A, B, and V, then, if it is adequately determined, the amount of money in the capital expenditures

It is not necessary to adjust for all parameters in this section. Daniy rozrahunok guidance from Dodatku V.

The results of the results will be followed by Table 4.1, to reveal the main indicators of the economical adaptability of the skin variant

Table 4.1 - Economic indicators of the corresponding options.


In such a rank, we rejected the most optimal variant of the scheme of the hedge, which is satisfactory to all the visitor's vimogs and the most economical. - Option 1.


5. Development and analysis of the established regimes

Meta tsiogo razdilu - prorahvati types of steel modes, characteristic of the chain of measure and value of reason and admissibility. At the same time, it is necessary to assess the possibility of "extreme" modes and the amount of effort required in the new elements of the net.

5.1 Manual opening to maximum mode

Preparation of tribute for manual delivery to the maximum mode

For manual rozrahunku mode, first for everything, it is necessary to know the parameters of the replacement circuit. When the given was folded, we went in addition to the fact that 2 okremo was installed on the skin substation, half of the transformer was installed. Charge the strain of the lines was carried to the її universities; the transformer is represented by a G-shaped diagram, in the yakiy of the transverse conductors is represented by the idle speed (XX).

So, as in SDO6, for the establishment of the university to complete the vicorist values ​​of the nominal tension and the effort to navantazhen (generation), then for the establishment of the array of tributes in the whole PVK to complete the vicorist table 5.1.

To set the parameters of the line in SDO 6, it is necessary to add the power of the power to the complex support, and not to charge the pull, like in a manual release. To that, up to Table 5.2, the capacitive capacitance is set in Table 5.3.

Table 5.3 - Gylok conductivity rating

A pair of vikoristov was carried out during a manual opening for the transverse conductivity of the transformer in the idle run of the transformer. For the installation of transformers in the PVK, it is necessary to replace them with the correct capacities of the chain, as indicated in Table 5.4. All іnshі dans also, scho і for manual opening (Dodatok E).

Pivotal analysis of manual racking of the maximum mode and racking behind the auxiliary PVC

For the adjustment in the military-industrial complex and manual, it is necessary to use the parameters of the adjustment. In this vypadku we will change the values ​​\ u200b \ u200bof pressure in all universities and the numbers of tap-changers in transformers. There will be quite enough for a quick release of manual and machine tools.

There is a certain amount of stress in all universities, the results are shown in Table 5.5

It is possible to say that with the accuracy of 5% on the PVC, the accuracy of the design will be sufficient. At the same time, the taps of the transformers converge at both positions.


5.3 Analysis of the tired regime

The structure of the input of electrical energy

Analyze the structure of the input for the three modes, which are secured behind the additional PVC.

The structure of the input for 3 modes is presented in Table 5.6.

Analysis of rivniv naprug in universities

For the analysis of the strengths and risks, the most important PA modes and the mode of minimum pressure are needed.

So, as we need to adjust the balance in all three modes, then the indications will be in the numbers of the tap changers.

In such a rank, the hedge is designed to allow for the hopeful and obvious harmlessness of the living with the electric power.

6. REGULATION OF SPRINGS AND FLOWS OF REACTIVE STRESS IN THE ACCEPTED VARIANT OF MEREZHI

Meta rozdilu - explain the stasis of vikorists by means of regulation of springs and dates of description.

6.1 Method for regulating spongi

The stress of the mesh is constantly changing at once due to the change in the setting, to the robotic mode of life, the support of the lancer. Vidhilennya naprugi must not be found in intervals of acceptable values. The reasons for this are: a) vprugi, wiklikayuyutsya struma navantazhennya, scho pass through the elements of the net; b) the wrong vibration of the strumming elements and the tension of the power transformers; c) incorrectly prompted the scheme of the hem.

The control over the release of springs is carried out in three ways: 1) for the rim - carried out by the way of realizing the springs with the permissible values; 2) behind the piece in the electrical system - it is conducted at the singing points of the mesh, for example, on the cob or at the end of the line, at the district station; 3) for the triviality of seeing the spasms.

Regulating springs is called the process of changing the springs at the characteristic points of the electrical system behind the addition of special technical means. Vikoristovuyutsya regulation of stress in the centers of the living of the growth of the fringe - at the regional production stations, in the process of change in the transformation of the growth in 200 /.

If necessary, on the tires of the secondary springs of the lowering stations, it will be ensured that the springs are adjusted in the intervals 0 ... + 5% of the nominal springs of the hem. Even before the additional graph is added, there is a total pressure to decrease up to 30% and more of the most important value, the pressure on the tires can be adjusted to the equal nominal tension of the grain. In the year of the greatest navantazhennya the spill on the tires is to blame for the nominal spill of the hem, not less than 5%; it is allowed to adjust the pressure up to 110% of the nominal, even if at all times it is not possible to change the most important value in the case of the closest survivors, but it is allowed by the Rules for the adjustment of electrical installations. In the case of emergency modes in case of intelligent regulation of the springs on the tires of the lower springs, it is innocent of the lower nominal springs of the hem.

In the capacity of special means of regulating the springs, beforehand, there can be used transformers with regulating springs for navantazhennyam (RPN). It’s unwise to take care of the preset value of the stress, so that the efficiency of the installation of static capacitors or synchronous compensators can be seen. / 3, p. 113 /. Tsiogo in our vipadku is not necessary, so as there is quite enough regulation of tension in the universities on the low sides behind the additional RPN.

Find out about the methodology for choosing the regulating transformers and autotransformers from the tap changer and the value of the applied stress.

The method is understandable, based on the non-mediocre design of the necessary pressure for regulatory visualization and is characterized, according to the authors' opinion, by simplicity and to the point.

As soon as the voltage on the busbars of the lower voltage of the station is brought to the upper side of the transformer, then it is possible to increase the tension of the regulating winding of the winding of the transformer


(6.1)

de - nominal winding of the lower winding of the transformer;

Fatigue, as it is necessary to trim the lower springs on the tires in the new robot modes and the hedge U H - in the highest voltage mode and in the emergency modes and U H - in the selected new mode);

U H - nominal netting.

For a hem with a nominal voltage of 6 kV, it is necessary to energize in the modes of the highest voltage and in emergency modes of 6.3 kV, in the mode of the lowest voltage of stench to become 6 kV. For a net with a nominal voltage of 10 kV, store 10.5 and 10 kV. Even in emergency modes, it is unwise to prevent the pressure U H, it is allowed to decrease it, but not lower than 1 U H

Stagnation of transformers from the on-load tap-changer allows the change of the control valve without connection. That is why it is necessary to start a spur of the regulatory maintenance environment for the most and the least maintenance. So, as the hour of the emergency regime is unavoidable, we will rescue the emergency regime in the most unpleasant vipad, that is, in the most uncomfortable year. According to what has been said above, the stress of the regulating transformer is based on the following formulas:

for the regime of the highest prices

(6.2)

for the regime of those who hired the day


(6.3)

for emergency mode

(6.4)

According to the known value of the rosacea of ​​the regulating vidgaluchennya, the standard is the vidgaluzhennya with the straining, the closest to the rozrahunky.

Singing in such a way is meaningful on the tires of the lower springs, quietly at the station, de-stashed transformers from the tap-changer, to get used to the meanings of the springs, which are meaningful.

On tri-winding transformers, the regulation of the tension before the installation is displayed in the winding of the secondary tension, and the winding of the middle tension is in the winding, as the change is only due to the knowledge of the installation.

7. VALUE COST OF ELECTRIC POWER TRANSMISSION

By means of a wide distribution of information on the importance of transmission of electrical energy in the design of the grid. A whole indicator of important marks є one of the indicators of adaptability to the whole project as a whole. On the basis of the transmission of electrical energy, the cost of the vitrat is used to equip the netting in the whole to the total average cost of living, rubles / MW

(7.1)

de - sumarni vitrati for all options with urahuvannyam vrat electric energy, rubles;

Average power supply of the project, MW.

de - the maximum amount of winter labor required for the given stock, MW;

Number of years for the maximum navantage, h.

In such a rank, the ownership of the transmission of electric power is 199.5 rubles. per MW for about 20 kopecks. per kWh

The rozrakhunok sobivarosti transmissions of electric power is directed to the supplement of E.


VISNOVOK

In the process of designing electrical fences, we have analyzed the tasks of geographic development of electrical energy. With a whole lot of analysis, the bully vrakhovani tediousness to the end of the life, they roztashuvannya again. On the basis of the patterns given by us, we will propose options for the schemes of electrical distribution, most of the time, the specifics of their folding are displayed.

For the additional development of the typical graphs of electric power supply, we have eliminated the characteristic characteristics, so that we can analyze with greater precision all the parameters of the modes in the projected measure of the electric power supply.

Also, the design options were adjusted according to the possibility of technical implementation, according to the hopes, from the economic contribution.

As a result of an economical pro-rakhunku, the most recent version of the EU schema is presented by us at a glance. For a wide variety of bullets, there are 3 of the most characteristic power systems for the regime, in which the bazhans showed a spout on the NN tires of all low-pressure substations.

The combination of the transmission of electricity in the proponent version of the warehouses is 20 kopecks. per kWh

Approved by the Order of the Ministry of Industry and Trade of the Russian Federation dated 22 February 2007, No. 49

1. Development of 4-5 options for the configuration of the hedge

When choosing options, it is necessary to take two minds: the hedge is guilty of the mother as far as possible; for a dermal resident in fallowness of the 1st category, the blame is not given to any steps of hope.

As long as the PUE is renewed, the 1st and 2nd categories of guilt will not be taken into account by the power supply from two independent power supplies, and the interruption of the power supply is allowed to be deprived of the automatic renewal for an hour. It is allowed to live with living in the 2nd category from one dzherel in case of a general technical and economic grounding. For power supplies of the 3 rd category, eat food along the same line, so that you can live from one dzherel, or, at the viglyadi branch, you pass near the line. As a criterion for setting options in the design for a given stage of the design, it is recommended to vicoristovuvati to summarize the line. The high-voltage (single-head) lines are increased by 20% through the communication lines of the power transmission lines from the direct lines through the changes of the relay of the link. Dovzhini double-headed lines multiply by 1.4 - at the style of the two-chain line in the context of the single-line line.

The whole criterion is to be used for starting up, but all the variants of the schemes can be of the same class of nominal tension and viconanity with the same connection of wires on all dilankas, moreover, the vicorias are of the same types of supports, construction phases, etc.

The configuration of the options in the hedge is given on small 1.1.

On the basis of a vicious acceptance for the most recent options for options 1 and 2. Offending options may be the length of the LEP hedge, according to the number of people who have come to the categories of living, may and may not.

For the nominal tension and re-straining of the wires for the reverse configuration of the hedge, it is necessary to develop the flows of pressure in the circuit heads. At the first stage of the project, the price of the project is approximated. As a close method, the method of contouring is used, so that the method, behind the help of which, the flow of the flow is carried out in two stages, if on the first stage you will be able to see it without having to spend less effort and retrace the rosters, and in the other Here the results will be victorious, taken away at the first stage of the electric rosary. Make sure to change your mind for the possibility of using the method, in order to start:

3. Vibir of nominal springs and numbers of lantsyugiv lines

The nominal tension is the main parameter of the mesh, which is the basis for the overall dimensions of the lines, transformers, power stations, communication devices and parts.

The return of the pressure is guilty of the adoption of the adopted systems of nominal pressure in the energy system of the region. The alternate vibration of the nominal stress is displayed in the economic zones, or for the empirical formulas:

4. Vibir to resist conduction and, if necessary, voluntary exertion of compensating attachments. Clarification of the configuration of the hedge

The wiring of the system-controlled lines is vibrated from the economical world and is converted according to the permissible current to the heating in emergency modes, and also behind the minds of the corona for 110 kV lines and food. Criteria є independent of one kind of one, and picking up the dart is guilty of satisfying the skin of them. The results of the rosters can be presented in the table 4.1. Tsі rosrakhunki vikonuyutsya for skin s poglanyutih options.

For the time being, the hour for the maximum nomination is T max = 5100 year for PS2 and PSZ, and T m ah = 5200 for PS4 and PS5.

So, since the meaning of T m ah is for survivors, then for a closed fence, T cf is known:

On all dylyankas of strumming in emergency mode, I do not change the permissible strum in terms of heating for return wires. The configuration of the hedge for options 1 and 2 should be left the same, like on the cob of roses.

It follows from the norms of technological design of power transmission lines with a 35 kV power supply.

5. Vibration of the number and demand of transformers at the station

At the stations, to live with people of I and II categories, for the uninterrupted power supply, the number of transformers is guilty but not less than two. The need for transformers is recommended to be vibrated on the mind of all survivors when one transformer is driven out of the fret and when the permissible overvoltage is up to 40%:

The need for a single-transformer power station to start with the maximum transformer shutdown in normal mode (up to 100%).

Coefficient of interlocking the transformer in normal and emergency modes:

6. Technical and economical adjustment options

In case of technical and economical adjustment of 2 options, it is allowed to corystuvaty by simplified methods of design, but itself: not to waste the pressure in the transformers and the lines in case of significant increase in the pressure in the measure; he knows that the pressure has risen in closed fences, not along the supports of the lines, but according to the lines; do not vrakhovuvati in the flow of charging strain of lines; Make sure to start pouring in according to the nominal nominals.

Rіchnі exploitation vitrati and the nature of the transmission of electric power does not characterize the whole world of productivity improvement, but doesn’t give a new indication of the efficiency of productivity until the lack of vitality. In general, an assessment of the efficiency of capital investment and economy of this type of production can be supplied only with a glass of vitrate of all the suspension technology necessary for production of products.
