Notes

1 In process of increase in a deviation of pressure and frequency from nominal excess of temperatures or temperature can progressively increase. Long work with rated power in some boundary currents of the shaded area can lead to growth temperatures approximately on 10 To.

Cars also should provide rated power at a nominal power factor at pressure change 5 % and frequency from plus of 3 % to a minus of rating values of 5 % as it is defined by external dotted border in drawing 1, however will take place thus the further increases temperatures.

2 For reduction of reduction of service life because of increase of temperatures or temperatures work of the car out of limits of the shaded area should be limited on duration and number of cases As far as possible capacity of the car should decrease or other measures should be undertaken

Turbogenerators should suppose long work with the lowered loading at simultaneous deviations of pressure over 5 %, but no more than to 10 %, and frequency to 2 % of rating values.Safe loads depending on their duration and number of cases of work out of the shaded zone should be specified the manufacturer in the car maintenance instruction3 Operating modes at the raised pressure in a combination to the lowered frequency or at the lowered pressure and the raised frequency are abnormal Thus work in the first of modes can lead to increase in excess of temperature of a winding of excitation. At the operating modes shown in drawing 1, overexcitation or the car and its transformer is not exceeded by 5 %.

4 it is necessary to consider influence of a deviation of frequency from nominal for work of other elements of a turbine unit, for example the turbine and auxiliaries the Manufacturer of the turbine should specify limits of change of frequency and time during which the turbine can work at this frequency. It is necessary to consider also possibility of work of auxiliaries at pressure and frequency change

4.5 Turbogenerators should be made for long typical operating mode S1 in accordance with GOST 183.4.6 Turbogenerators should be made a climatic modification At a category 3 in accordance with GOST 15150.

4.8 It is supposed to connect a winding in a star or a triangle, and if connection in a triangle winding connection in a star means specially is not specified. In any case if another is not provided by the agreement, the winding should have not less than six conclusions.

4.9 Nominal are those values of a current and pressure of a winding of excitation at which are provided nominal full capacity, pressure and a power factor at nominal frequency and pressure of hydrogen (for cars with hydrogen cooling), and the temperature of a winding of excitation corresponding to temperature of the primary cooling environment for the above-stated conditions of loading at the maximum temperature of the final cooling environment, specified in the standard document on the car.

At presence at the car of contact rings the excitation rated voltage includes also a power failure in the shchetochno-contact device.

4.10 If the agreement does not stipulate other the systems used for windings, on should be not below a class In in accordance with GOST 8865.

The maximum temperatures of conductors of windings, an active steel and the constructive parts of the car adjoining to isolation, at long work with loadings should not be till 4.17 above supposed GOST of 8865 values, according to a class the applied isolation.

Limiting supposed values temperatures or temperatures of active parts in a nominal mode depending on methods of their measurement should be specified the manufacturer and to be no more resulted in table 1.

4.11 Design of a winding a turbogenerator identical electric durability of isolation in front and grooving parts of a winding should be provided.4.12 Resistance of isolation of windings a turbogenerator concerning the case and between windings at temperature 1030 should be not more low 10 on each kilovolt of rated voltage of a winding (at water cooling after a purge and windings air).For more heats supposed resistance of isolation decreases twice on everyone 20 differences between temperature at which measurement is carried out, and 30 .Resistance of isolation of windings in all cases should not be less than 0,5 .4.13 Isolation of windings should pass test for electric durability concerning the case of the car and between windings, and also test isolation in accordance with GOST 183 and GOST 11828.

Isolation of a winding of excitation should be tested for electric durability:

- The test pressure equal to tenfold rated voltage, but not less than 1500 In at rated voltage of a winding of excitation to 500 In;

- The test pressure equal 4000 In, plus the doubled rated voltage at rated voltage of a winding of excitation over 500 Century

4.14 In the car the measures interfering course of currents and their short circuit on the earth should be provided.

The turbogenerator bearing, oil consolidation of a shaft and (in cars with hydrogen cooling), shaft consolidation (in cars with air cooling) from the party opposite to the turbine, bearings of directly attached activators and , and also water supplies to a shaft and reducer bearings (if those are available) should be isolated from base plates and .The electric resistance of this isolation measured by pressure 1000 In, should be not less than 1 . Isolation from currents should be executed so that it could be supervised in the course of car work.

4.15 Rotors of turbogenerators should pass test at the raised frequency of rotation equal of 1,2 nominal frequencies of rotation, within two minutes if other is not established under the agreement.

4.16 Critical frequencies of rotation of a rotor as a part of a turbine unit should not cause emergency operation at operation, change of frequency of a current in the limits specified in 4.4.

4.17 Manufacturer in the maintenance instruction should result the loading diagramme showing limits of work of a turbogenerator on jet loading Q depending on active capacity , caused in admissible temperatures or temperatures, and in necessary cases also static stability of the car. The diagramme result for an operating mode with nominal pressure, frequency of a current, temperatures of cooling environments and pressure of hydrogen (for cars with hydrogen cooling).

On heatings in face zones turbogenerators should suppose work with nominal active loading in a mode of consumption of jet capacity at a power factor equal 0,95.

The typical diagramme is resulted in drawing 2.

Drawing 2

Diagramme borders are defined by following restrictions:

- The curve And corresponds to work with excitation rated current and consequently is characterised approximately by constant excess of temperature of a winding of a rotor;

- The curve In corresponds to work with rated current and is characterised approximately by constant excess of temperature of a winding ;

- The curve With shows a limit caused by local heatings in a face zone or static stability of the car, or a combination of both effects.

To point there corresponds rated power.

Under the agreement between the manufacturer and the customer it is necessary to result as well other diagrammes for working conditions at deviations of pressure and frequency according to 4.4 and parametres of the cooling environments differing from the nominal. The generator should work within diagramme borders under the set conditions on pressure, frequency, to temperatures of cooling environments and pressure of hydrogen. Work out of borders can lead to reduction of service life of the car.

4.18 Turbogenerators should without damages and residual deformations to suppose an overload on a current frequency rate of 1,5 rated currents during:

Two, minutes at indirect cooling of a winding;One minute at direct (gas or a liquid) winding cooling.Rotors of turbogenerators should maintain two-multiple rated current of excitation during not less:50 with for turbogenerators with indirect cooling of a winding of a rotor;20 with for turbogenerators capacity less than 800 with direct cooling of a winding of a rotor;15 with for turbogenerators capacity from 800 to 1200 ;10 with for turbogenerators capacity 1200 and more.Turbogenerators should maintain without damages of an overload with other combination of frequency rate of currents and their duration provided that additional rise in temperature of corresponding windings during an overload remains invariable.

Admissible in emergencies of duration of overloads and a rotor depending on frequency rates of currents in windings should be specified the manufacturer in the car maintenance instruction.

The note At overloads of temperature of windings can exceed reached in a nominal mode, therefore in a machine design should be considered, that number of overloads of limiting duration on the average no more than two in a year.

4.19 Turbogenerators should suppose long work at asymmetrical loading if currents in phases do not exceed rating value, and currents of return sequence do not surpass 10 % of rating value of a current at indirect cooling of a winding of a rotor and 8 % at direct. Rise in temperature of active parts of cars on 5 is thus supposed.4.20 Turbogenerators on thermal firmness of a rotor at short-term work in asymmetrical modes should maintain thermal influences at values of product of a square of a current of return sequence in relative units on a supposed operating time in seconds in an asymmetrical mode not less:

30 with for turbogenerators with indirect cooling of windings;15 with for turbogenerators with indirect cooling of a winding and direct cooling of a winding of a rotor;8 with for turbogenerators capacity to 800 inclusive with direct gas or liquid cooling of windings and a rotor;6 with for turbogenerators capacity from above 800 with direct hydrogen or liquid cooling of windings and a rotor.4.21 Idling with rated voltage at nominal frequency of rotation the factor of telephone harmonics in linear pressure should not exceed 3 % for turbogenerators capacity to 5000 kw inclusive and 1,5 %-for cars capacity more than 5000 kw.

4.22 Turbogenerators should maintain without damage sudden short circuits of any kind on winding conclusions at a rated load and the pressure equal 1,05 nominal, provided that maximum current in a phase is limited by external means and does not surpass the maximum current in a phase at sudden three-phase short circuit. Without damage means, that the damages interfering continuation of operation of the car though some deformations of a winding can take place should not take place.

If test for sudden short circuit spend by the new car it should be carried out after check of isolation of a winding on electric durability full test pressure in accordance with GOST 183.

In a case when the generator is intended for work on the general tyres, test for sudden three-phase short circuit should be spent from an idling mode at rated voltage. Test for sudden short circuit of turbogenerators, which join a power supply system through the transformer or a reactor (usually with the help closed ), spend from a mode of idling by the pressure equal of 70 % nominal, if are not co-ordinated other its lowered value, proceeding from a condition that the current of short circuit of the generator was same, as well as in case of three-phase short circuit on conclusions of the transformer or a reactor from a power supply system at work idling with rated voltage.

Turbogenerator consider passed test for sudden short circuit if the car it is possible at once or after insignificant repair of a winding to include in a network and if the car has passed test of isolation by the pressure equal of 80 % of test pressure, provided GOST 183 for the new generator. Insignificant it is considered small repair of fastening of front parts of a winding or the external insulation layers, not connected with replacement of cores.

The note Is abnormal high currents and the rotating moments can arise in operation in cases of short circuit close to the generator or switching-off and repeated inclusion of the car at more remote damage, and also at erroneous synchronisation. If at such modes splashes in the raised currents it is recommended to check up carefully the car took place, paying special attention on a winding . Before generator introduction in work it is necessary to eliminate any easing of fastening of a winding in order to avoid its possible damage caused by vibration; also it is necessary to check up possible deformations , and bolts .

4.23 Standard minimum values of the relation of short circuit () are resulted in 5.3 and 6.5.

Big minimum values can be established or co-ordinated, but thus some increase in the sizes of the car usually is required.

4.24 Values transitive xd ' and supertransitive xd "inductive resistance on a longitudinal axis should be established or co-ordinated with the account of working conditions of turbogenerators in a power supply system.

It is recommended to establish or co-ordinate the minimum value xd "at the level of saturation corresponding to rated voltage, and the maximum nonsaturated value xd ' at rated current. As xd" and xd ' in degrees are defined by the general magnetic streams it is necessary to mean, that xd "and xd ' are connected with each other and it is impossible to choose the top limit xd" too close to the bottom limit xd '.If another is not stipulated, xd "should be not less than 0,10 . A unit at the level of saturation corresponding to rated voltage.

xd "and xd ' can be established or co-ordinated also at other level of saturation.

If makes a reservation, that xd "and xd ' should be defined by practical consideration tests should be spent according to GOST 10169.

Thus if:

- The limiting values provided by this standard or other limiting values , xd "and xd ' are established or co-ordinated, at the co-ordinated minimum value without the negative admission and the positive admission of 30 %, and at the co-ordinated maximum value without the positive admission and the negative admission of 30 %;

- , xd "and xd ' are established, but their limiting values , xd" and xd ' it is necessary to consider as rating values with the admission 15 % are not defined;

- , xd "and xd ' are not stipulated or are not co-ordinated, they are established by the manufacturer with the admission 15 %.

6.4 Standard power factor on car conclusions accept equal 0,8 for turbogenerators capacity to BUT and 0,85 or 0,9 (overexcitation) for turbogenerators capacities.

The note other values cos Can be co-ordinated,( thus it is necessary to mean, that at smaller values cos the turbogenerator (will have the big sizes.

6.5 Measured values at rated voltage and rated current should be not less:

0,45 for turbogenerators capacity to 200 inclusive;

0,40 """St. 200 800 0,35 """ 800.

With face boards and covers of coolers at use of hydrogen cooling internal explosion of the formed explosive mix should maintain 6.6 cars Collected the case at atmospheric pressure without danger to attendants. On request of the customer it is necessary to conduct tests by hydraulic pressure for check of durability of the case and boards. Such test should be spent at superfluous pressure 800 within 15 minutes

6.7 car insulators at hydrogen cooling should maintain superfluous pressure of gas not less than 800 .

It is supposed insulators on dielectric durability to test separately from the car. Tests spend on air during 1 mines at pressure not less than 1,5 multiple test pressure of a winding of the car.

The note - When conclusions have liquid cooling connection of liquid cooling is not obligatory at high-voltage test.

6.8 Temperature of primary cooling environments (coolants) of turbogenerators, except resulted in rotation by gas turbines, should correspond to requirements of GOST 183.

The maximum temperatures of primary coolants (hydrogen, a liquid) at nominal or the stipulated maximum loadings can differ from 40 (for example for application of the optimum heat exchanger with the set maximum temperature of a secondary coolant). In this case:

- With indirect cooling it is necessary to apply the corresponding points concerning calculation admissible of temperatures for cars with air cooling to cars;

- With direct cooling the temperatures resulted in table 1 should be applied to cars without changes.

The note to avoid excessive or changes of temperatures, the maximum temperature of a coolant usually should not deviate from 40 more than on 10 To.

Requirements to temperature of a primary coolant for the turbogenerators resulted in rotation by gas turbines, are resulted in 7.3 and 7.8.

6.9 Design of a turbogenerator should allow its use at nominal pressure of gas (superfluous) at height above sea level to 1000 m.

The note Is supposed work of standard cars with rated power at installation at the height exceeding 1000 m above sea level provided that the system of gas cooling provides nominal pressure (absolute) a primary coolant (hydrogen) irrespective of installation height. Thus between the customer and the manufacturer agreements concerning consolidations of a shaft, the case and auxiliary equipment should be reached.

6.10 For cars with direct cooling the temperature measured by built in gauges, does not define temperature of a hot point of a winding . Thus, if the maximum temperatures of a coolant on an exit from the cooled active parts, resulted in table 1, are not exceeded, temperature of a winding do not consider excessive.

The limit of the supposed temperature of a winding on gauges is intended for the prevention of excessive heating of isolation from the core. Indications of the built in temperature gauges can be used for the control of work of system of cooling of a winding.

For turbogenerators with liquid cooling of a winding possibility of the control of heatings of a winding in each parallel branch of a cooling liquid and the control of temperature of the core not less than in six points should be provided.The number of the temperature gauges intended for measurement of temperature of the cooling liquid on an input in the car, should be not less than two.

With direct cooling of a winding the coolant temperature on an exit from a winding should be measured in cars, at least, by three temperature gauges, thus gauges should be in direct contact to a coolant:

At gas cooling of a winding gauges should be established so close from exhaust outlets from cores, how much it is supposed by rules of electric safety;

At water cooling temperature gauges should be established in pipelines in the case of the car or is so close from a place of an exit of a coolant from the case, how much it is practically realizable to avoid a considerable difference between temperature in a point of measurement and temperature at which the coolant leaves a winding.

6.11 Coolers (, heat exchangers) if it is not stipulated differently, should be calculated on temperature of entering water to 32 and working superfluous pressure of water not less than 350 .

Test pressure should be in 1,5 times above the maximum working pressure and is enclosed within 15 minutes

If pressure of water in a cooler supervise by means of the gate or other device lowering pressure which is connected to system of water supply with pressure more than working pressure in a cooler coolers if another is not stipulated, should be executed on pressure in system of water supply and are tested by pressure in 1,5 times big this pressure. The raised pressure in water supply system should be stipulated the customer or is established by the manufacturer if the system of water supply of coolers is included into the complete set of delivery of the generator.

In some operational modes, and also at operations of filling of the case by hydrogen or its clearings of hydrogen, coolers can be exposed to pressure of gas in the absence of pressure of water. Therefore coolers should be carried out taking into account influence of pressure 800 from gas.

Coolers should be executed so that at switching-off of one section, for example for clearing, the turbogenerator could is long to bear not less than 2/3 rated loads (under the agreement with the customer a little smaller loading is supposed) without excess of admissible temperatures of active parts of the car. At work in this mode the temperature of a primary coolant can be above settlement.

6.12 Turbogenerators should be calculated on application of distillate for cooling of windings and a rotor with electric specific resistance not less than 2000 at temperature 25 and should suppose short-term decrease in electric specific resistance of distillate to 500 .6.13 For normal work of the turbogenerators considered in section 6, auxiliary systems (the list of systems is not considered settling, other systems and devices can be applied also) are required:

- System of gas cooling (hydrogen or other gas) with regulators of the control of pressure of gas in the car, with maintenance of possibilities of connection to systems of gas supply and gas;

- System of inert gas for a case purge (usually dioxide of carbon or nitrogen). Possibility of connection of this system to system of gas cooling and safe performance of operations of replacement of hydrogen Should be provided.

If for removal of inert gas after hydrogen replacement use station system of the compressed air which connection should be executed so that air got to the car only at operation of removal of inert gas, for example by use of one rearranged branch pipe;

- Devices for the control and the alarm system of degree of cleanliness of hydrogen in the case, and also cleanliness of inert gas at operations of replacement of hydrogen. It is necessary to use two independent means for the control of degree of cleanliness of hydrogen;

- The equipment for the control of condensing oil and, in case of need, for removal from gas and water oil.

The system emergency the consolidations, joining should be provided automatically at refusal of the basic system ;

7 Turbogenerators resulted in rotation by gas turbines

7.1 Present section extends on the turbogenerators resulted in rotation by gas turbines, with the opened system of air cooling, and also with the closed system of cooling by air or hydrogen. As a final coolant water or air can be used.

Requirements concern also the generators disconnected from the turbine working as synchronous jacks.

7.2 Generator resulted in rotation by the gas turbine, should bear loading according to its rated power and loading possibilities under the conditions of operation stipulated by the standard.

7.3 For generators with the opened system of air cooling in temperature of a primary coolant is the temperature of air entering into the car usually corresponding to temperature of air. Limits of change of temperature of entering air are defined by the customer, usual limits of change of temperature are from a minus 5 to plus 40 "With.For cars with the closed system of cooling, temperature of a primary coolant the temperature of air or the hydrogen entering into the car from is. Limits of change of this temperature are defined by the manufacturer for reception of an optimum machine design and the coolers, based on limits of change of temperature of a secondary (final) coolant (air or water) in accordance with GOST 15543.1 or set by the customer.

7.4 Number of start-up in a year with a loading set should not surpass 500.

7.5 Speed of a set of active loading the generator is defined by the turbine.

Speeds of a set and change of active and jet loadings by the generator are not limited.

At the customer's request turbogenerators should provide start-up installations by frequency way at a food from the starting arrangement.7.6 Rated power of the generator is its long full capacity on conclusions to an installation site at nominal pressure and frequency of a current, a power factor and pressure of hydrogen (for cars with hydrogen cooling) at the temperature of a primary coolant equal 40 if another is not co-ordinated.

Rated power of gas turbines define at temperature of entering air 15 , and generator rated power define at temperature of entering cooling air or hydrogen 40 . At identical loading characteristics the gas turbine and the generator have different rated power.

At rated power should not be exceeded temperature or excess of the temperatures, resulted in table 1.

If other is not co-ordinated, generator parametres define with reference to rated power.

7.7 Loading characteristics define the greatest possible full capacity under the co-ordinated conditions of operation.

7.8 Basic capacity define long full capacity on generator conclusions to a place of its installation at nominal frequency of a current, pressure, a power factor and pressure of hydrogen (cars with hydrogen cooling). The range of change of basic capacity corresponds to a range of change of temperature of the final coolant defined for an installation site of the car (7.3). Thus excess of temperatures or temperature should not surpass defined in 7.9.

1 basic capacity; 2 peak capacity; 3 basic and peak capacities for cars with length of an active part of the core less than 2,5 m; 4 basic and peak capacities for cars with length of an active part of the core 2,5 m and more, 5 a rated power point; a scale And temperature of cooling air of cars with the opened system of cooling, a scale In temperature of a final coolant for cars with the closed system of cooling at use of air or hydrogen as a primary coolant

Drawing 3

Notes

1 For the generator with heat exchangers is not obligatory reduction of a scale for temperature of a primary coolant. Two scales for a final coolant are resulted to show forms of diagrammes.

2 At temperatures of a primary coolant more low 10 cars with active length of the core 2,5 m and more work with the fixed limiting excess of temperature. The small increase in capacity of the generator probably because because of decrease in the general temperature decreases resistance of a winding.

Basic capacity of the generator in watts, on car EFFICIENCY, should be equal or should exceed basic capacity of the gas turbine in the co-ordinated range of change of temperature of air on a turbine input on a place of its installation.

The manufacturer of the generator should give a curve of dependence of basic capacity of the car for the co-ordinated range of change of temperature of a final coolant on a generator installation site.

Typical curves of loading possibilities of the generator are resulted in drawing 3.

For cars with the opened air system of cooling the coolant temperature is close to air temperature on an input in the turbine (drawing 3, a scale).As agreed between the manufacturer and the customer it can be accepted, that below some stipulated temperature of air basic capacity of the generator is a little bit less than capacity of the turbine at satisfaction of all other requirements to the generator.

In cars with the closed system of cooling by air or hydrogen at use water the range of change of temperature of water (a final coolant) usually is less, than a range of change of temperature of air on a turbine input.

Hence, at decrease in temperature of air increase of capacity of the generator will be smaller, than at the turbine, and the sizes of the generator will be defined by capacity of the turbine at low temperatures of air that can lead to unfairly overestimated capacity of the generator at usual temperatures of air.

In these conditions the agreement on restriction of loading ability of the generator gets great value in an establishment of the optimum sizes of the car.

In cars with the closed system of cooling there is no idle time or constant dependence between air temperature on an input of the turbine and temperature of cooling water. Therefore in drawing 3 loading ability of the generator is presented depending on temperature of a final coolant (water) on a scale of Century

Taking into account told between the manufacturer and the customer the agreement on degree of conformity of loading abilities of the generator and the turbine should be reached.

7.9 For cars with indirect cooling of excess of temperatures at generator work on an installation site with basic capacity should correspond to table 1 with following changes:

- For temperatures of a primary coolant from 10 to 60 to the values of temperatures established in table 1 to add (40 minus temperature of a primary coolant) To;

- For temperatures of a primary coolant from a minus 20 to plus 10 at length of an active part of the core;

1) less than 2,5 m to the values of temperatures established in table 1 to add 30 To plus 1/2 (10 minus temperature of a primary coolant) To;

2) 2,5 m and more to the values of temperatures established in table 1 to add 30 To;

- For temperatures of a primary coolant more low a minus 20 or above 60 under the agreement between the customer and the manufacturer.

For windings with direct air or hydrogen cooling of temperature at generator work on an installation site should correspond to table 1 with following changes:

- For temperatures of a primary coolant from 10 to 60 without changes;

- For temperatures of a primary coolant from a minus 20 to plus 10 at length of an active part of the core;

1) less than 2,5 m from values of the temperatures established in table 1 to subtract 1/2 (10 minus temperature of a primary coolant) To;

2) 2,5 m and more from values of the temperatures established in table 1 to subtract (10 minus temperature of a primary coolant) To;

- For temperatures of a primary coolant more low a minus 20 or above plus 60 under the agreement between the customer and the manufacturer.

7.10 Peak capacities define long full capacities on generator conclusions to an installation site at nominal frequency of a current, pressure, a power factor and pressure of hydrogen (at its application). The range of change of peak capacities corresponds to a range of change of temperature of the final coolant defined for an installation site of the car (7.3). Thus excess of temperatures or temperature should not surpass the values defined at 7.11.

Positions 7.8 concerning a parity between basic capacities of the generator and the turbine concern also their peak capacities.

7.11 For cars with indirect cooling limiting excess of temperatures for peak capacity can be on 15 To above specified in 7.9.

For cars with direct air or hydrogen cooling of windings limiting temperatures can be on 15 To above specified in 7.9.

The note Work at peak capacity will lead to service life reduction as thermal ageing of isolation will approximately occur in 3 6 times faster, than at the temperature corresponding to base capacity of the generator.

7.12 On the tablet of the car the manufacturer specifies all data according to 12.1 and 12.2, and also peak capacity at temperature of a primary coolant for which the generator rated power is defined.

7.13 Thermal tests should be spent at a rated load and temperature of a primary coolant for which the car rated power is defined. It is supposed under the agreement to conduct thermal tests at any temperature of a primary coolant and corresponding base capacity. Temperature or excess of temperatures should correspond to requirements 7.9 with the amendment, in case of need, a difference in heights of an installation site and a place of tests it agree GOST 183.

7.14 At the customer's request generators should suppose work possibility at a detachment from the turbine in a mode of the synchronous jack. Base and peak capacities in modes of delivery and consumption of jet capacity at work as the jack should be co-ordinated.
