GH/T 2820.12—2002
The long-term power grid drop of 0 phase is comfortable, and the factory is in use. The power conversion time is required for its safety and other settings. The design of the generator set takes the power of the power plant and the power of the power plant as the reference. The power of the two electric units is reversed by 100%! Let the power of the two electric units be tested for a short time. The power of the two electric units is determined by the power of the two electric units. The voltage of the power grid drops to 100% of the required power, and the power grid power generation rate exceeds the rated voltage, and the effective time is long. After 15 days of large switching time, the user's transformer should not be able to obtain the required power through two drinking and adding properties within 5 days. The power of the power generator set is designed to be 100%.1 Determine the required power. In order to ensure the reliable power supply of the generator, the power quality requirements should be informed of the expansion group manufacturer. For secondary density requirements, it also includes switching to electrical equipment (such as: electrical amplifiers, wind turbines, state-of-the-art equipment and other linear electrical equipment) when there is a short load. In the case of light-sensitive applications, in order to leave a margin, multiple units can be used in parallel. Most modern internal combustion engines are giant worm gear engines. Therefore, it is necessary to set the load acceptance capacity of the generator set according to the load acceptance capacity of the core. The braking half of the engine is effective. Therefore, the load acceptance characteristics of the load given in Chapter 1 of GB283.1997 and Figure 7 are used. If you want to compare only the June/2320.51S97 Figure 6, Figure 7 is a step forward to compensate for the greater cost, then appropriate additional measures should be taken, or the rated power of the proposed increase can be increased when the cruise ship is used. The design investigation list in the first section is necessary when designing the generator set. In order to ensure the normal operation of the generator set for a certain period of time, the necessary equipment of the generator set should be provided, such as the cooling system including the fuel system and the lubrication system. The refrigerant system should be non-standard. 7.2 Determination of power

table 3 to table 7 The specific requirements of the wall example are as follows: the number 2205 AM printed out the power method of using the production price of light can also be seen (the assumption of the bottom clause of the certificate is not A. The generator year is larger than the VA motor group. The teaching and examination standard is only for the power line of the world to ask you to be negative or neutral. The additional requirements of the day are as follows: HHKAoNT KAca
The power station with emergency test and control should be powered by a battery for standby. This method is based on the requirements of the China Consulting Association 81
G/T-3337.1 and IFC2.
This type of engine can be used for a small part of the voltage. In addition to the automatic start of the engine and the control circuit, it cannot be used for other purposes: when the ambient temperature is low and the power is in a floating state, the capacity of the battery can provide enough current to start, control and control the generator set. The total start-up time is 1 start-up interval of 5 times: the original energy-boosting generator set is started three times. Each time the drive (electric shock), the low battery voltage should not affect the control system. For each battery, the control type should be detailed. In terms of equipment, the equipment has certain physical and mental functions and is used for charging (cable out of the north), and can be converted into a floating state during charging: The charging terminal can charge the battery to its rated capacity of A under the specified conditions:
Category 4 power group: within:
Category 3 single unit: within:
In addition to charging the battery, the charging equipment should provide sufficient energy for operation, and the over-voltage detection and control should be changed to continuous (stop) operation. It should provide a device that can monitor the frequency of long-term operation and implement warning supervision. The line should be designed in accordance with the market's large European model. The night alarm terminal can be reset at the permanent land test tube when the tube is started by: short tire voltage staleness (for example: starting or charging while running must not lack the limit:
G/T 282C.*22002
When the battery charger fails (such as: AC system or automatic circuit breaker), it should be able to send a message, etc.
The battery is overcharged and its related system should be designed so that the control is reliable. The power supply should not be too long away from the maximum rated voltage of the control equipment.
The specifications of the starting cable should be determined by: When the generator or starter is started, the total voltage drop on the battery should not exceed the nominal voltage of the battery. If a separate battery is used to control the generator and the user's power generator, a charger should be provided according to the relevant provisions of this standard.
8.2 The specifications and digital display of the compressed air cylinder for the starting engine should be increased: In both hot and cold conditions, it can make the engine run at more than or twice the speed of the fire. The inflator system is a virtual valve supply and wax machine system. The inflation system should be able to quickly apply the internal pressure to the working area within 45m, and the bottom pressure of the gas can always be displayed. If the required pressure cannot be maintained, an alarm will be issued. Each gas cylinder has a power or actuation device. 8.3 The fuel supply of the fuel-driven generator is sufficient for the continuous power supply of the supplier. The fuel supply of the Class 2 generator set is sufficient to enable the generator to operate at a rated power of at least 81. For the Class 4 generator set, including the oil for trial operation, the oil supply should be sufficient to operate at least 26 at the rated power. When a natural fire occurs (such as when the ground screen is on), the generator set must be powered. [This is called the longest time of operation. This is called the result of the negotiation between the system and the production on the specific power supply business. The priority should be increased according to the main amount of oil injection (supply: the amount of oil sales must be to make the unit run at a power of less than 2b in the table. The correction pen should be placed close to the engine: In order to ensure that the generator can be started, the bottom of the fuel tank should be at least one level higher than the engine's fuel ticket. Unless the engine manufacturer has specified, there should be two oil-gas components on the upper continent: in order to gradually avoid overfilling, there will be enough leakage. Provide appropriate protection measures without continuous bleeding and blockage. Other requirements for the quantity should be made and the oil pen should be used as the capacity indicator or the ruler as the capacity indicator. 84 The movable communication card can be used to verify that the main power supply can be switched to a half-automatic power supply. 8.5 The common power supply system is shorter than 0.5: The power supply should not be disconnected or the engine should not be disconnected from the power supply and the heat should not be interrupted. 8.6 When necessary, the total time control should be accurate and effective. Six! : When the area reports the emergency information of the group and the quarterly mail of the group, the special high-security power supply is installed, complete: The safety rate of the increase and the charging agent are not adjusted, and the industry is also out of regulation. That is, the emergency product research and development group will inevitably become "the second time the expensive power will be more than the general demand, and the emergency power generation product will be managed through the virtual safety device for a longer time. To the commonly used power supply system to get compensation, under some special circumstances, the natural time reached 155) "95 volume on January 1, the Kobe area suffered two disasters: zero repair: the power supply system of some households in Sichuan Province was compensated for the month,
due to the good work of the lower camp kidney order production: the book cover color power generation group occurred the second time the damage product could not be started in time, this must depend on the emergency power generation group network 1.

10 Test method
10.1 Simultaneous power supply test with the power grid
HKoN KAa-
and a generator are usually tied to the power grid. Simultaneous power supply with the power grid H uninterrupted operation test is completed according to the following requirements. 10.1.1. No switching to add level
The manual and automatic type generator sets are close to the grid efficiency and self-pressure. After the generator circuit breaker is connected, the speed governor of the internal combustion engine is adjusted to achieve the desired bypass and the power required by the equipment, and the generator sets are connected to the grid for testing. After the test is completed, the generator set is loaded by reducing the rated speed of the inverter. When the power is less than % of the rated power, the generator circuit breaker is closed,
For this purpose, it is necessary to provide the appropriate generator protection equipment and close the control equipment! See G Section 22547.2) In order to determine the protection function of the new requirements and identify grid faults: cooperate with China Grid to conduct weekly tests as necessary. 10.1.2 There is a flash-change continuous drive loading operation
Use manual and dynamic methods to make the generator set close to the power and pressure of the industry grid: After the new automatic machine is synchronized, the protection is used to increase the output space of the generator set through the verification of the engine speed governor: the power supplied by the China Grid is the rated power of the generator set: 0%, the grid The circuit breaker should be disconnected. In order to ensure that the equipment and generators used under the power supply are connected to the power grid, the test station should carry out the following work in reverse order:
For this purpose, it is necessary to provide appropriate generator protection equipment and special control equipment (GB/2820.1 5.1 and 7.2). In order to determine the depth of protection required by the power grid and identify network faults, it is necessary to conduct coordinated tests with the power grid. 15.1.3 Test with ground wells | |tt||Use the automatic or automatic mode to make the generator set close to the frequency of the power grid. When synchronized with the power grid, the generator circuit breaker is closed after a certain time, the power grid breaker is immediately disconnected, and the power consumed by the generator is immediately oversupplied. In order to prevent the generator from overloading and out of service, it is necessary to ensure that the load reduction of the equipment is within the scope of the equipment, and it cannot exceed the power of the first stage specified in the equipment. The power and power will be connected to the grid without disconnection. In order to reconnect the power grid with the power equipment and the generator set without power failure, the above replacement procedure is reversed. The prerequisite for this is that all user loads are transferred to the grid within the specified time. For this purpose, it is necessary to mention the protection equipment of the generator and the relevant control equipment (/28.4 5.): In order to ensure the protection required by the grid and control the grid failure, the necessary 1C.2 of the coordinated test with the grid is not supplied at the same time as the grid
GI/T 2820.122002
For the purpose of testing the power supply of the simulated network, the network should be disconnected. The interruption of the power supply to the equipment shall be caused by the constant replacement of the starting and service performance characteristics of the generator set in Chapter 6. The test shall be carried out as follows:
Class 3 generator sets shall be tested in accordance with 10.1.1 or 10.1.2, and Class 4 generator sets shall be tested in accordance with 10.13.

11.2 Installation test
) The test items listed in the series provide a reference for correctly determining the capacity and performance of the generator set in the order of operation. The generator should be put into operation at the beginning of the period, but before it is put into operation or after it is put into operation, these tests should be carried out according to the general situation in the distribution network: a) The emergency generator set supplies power to users; b) Carry out safety inspection on the room where the generator is installed: fire prevention, network information, gas distribution, etc.; when confirming the current qualification of the generator set, consider the possible starting current of the load (for example: motor, fan, attenuation of power supply, etc.);
The user equipment of the generator set must meet the following tests, especially the following tests: the operation test of the emergency power generation group, including: \dynamic test, operation test of auxiliary equipment and control equipment, etc.: the total energy consumption when operating at rated power is tested as a generator set during operation. The dynamic difference of the power generation suppression rate should be obtained.
Check whether the local fire protection requirements are met.
11.3 Periodic test
11.3.1 In addition to the planned test of the power station according to the provisions of 1F04-7-710, the remaining tests are as follows: a) Perform operation test on the power supply of the main equipment at the end of the month, including: - Monitoring the battery grid voltage - Starting and commissioning compliance - Monitoring the load connection characteristics of the switchgear, the performance of the equipment and auxiliary equipment 1) Monitor the load cut-off characteristics of the emergency generator. The emergency generator should be operated at least at the predetermined power level of 5/10. If the equipment is not suitable for the use of the equipment, the generator can be driven in reverse without reverse operation. C: After the equipment is shut down, it is necessary to carry out operation test. 11-3.3 Annual inspection to verify that the generator set can still meet the design requirements of the equipment: the inspection records should be kept and the test time should be no less than "year 2 rating label
