Fig. 1 is a schematic diagram of a diesel engine power supply system in an embodiment of the present application, where LGB/C is a unit bus, LHA/B is a 6.6 kv emergency bus, LHP/Q is a diesel engine providing an emergency power supply, and 001JA and 002JA are emergency bus switches. In addition, LKE/D, LLC/D, LLC/B and LLG/W are 380 volt Alternating Current (AC) buses, LBA/B is 125 volt Direct Current (DC) buses, and LCA/B is 48 volt Direct Current (DC) buses.
Taking a diesel engine in the row a as an example, in a hot standby condition, the emergency bus switch 001JA is in a closing state, and the emergency bus LHA is supplied with power by an external power supply (LGB). 48V direct current, 125V direct current and 380V alternating current power supplies of a diesel engine control system, an excitation system and an auxiliary system are all supplied with power through an emergency bus LHA, and the 48V direct current power supply, the 125V direct current power supply and a storage battery of the control system and the excitation system are used as backup power supplies.
Referring to fig. 2, an embodiment of a method for testing a diesel engine started when an emergency bus of a nuclear power plant loses power in an embodiment of the present application may include:
step S201, obtaining an emergency bus power-off starting diesel engine test instruction, and determining a currently adopted target test mode according to the emergency bus power-off starting diesel engine test instruction.
Specifically, a test mode identifier can be extracted from the test instruction of starting the diesel engine when the emergency bus is powered off; if the test mode identification is a preset first identification, determining that a currently adopted target test mode is a segmented test mode; and if the test mode identifier is a preset second identifier, determining that the currently adopted target test mode is a complete test mode.
And S202, executing an emergency bus power-off starting diesel engine test process corresponding to the target test mode to obtain a test result corresponding to the target test mode.
Specifically, if the target test mode is a segmented test mode, the emergency bus power-loss starting diesel engine test flow may be divided into a first segmented test flow and a second segmented test flow, and the first segmented test flow and the second segmented test flow are sequentially executed, where the first segmented test flow is used to test a trigger process of a diesel engine starting command, and the second segmented test flow is used to test a starting process of a diesel engine.
In the first segment test process, a low-voltage relay of the bus can be tested to check whether a low-voltage signal can normally trigger a diesel engine starting command. In the second subsection testing process, a diesel engine starting command can be issued to the diesel engine automatically or manually so as to check whether the diesel engine can be started normally after receiving the diesel engine starting command, and reach a rated parameter within a required time, and the outgoing switch is switched to realize a loading function.
It should be noted that, in the segmented test mode, the first segmented test flow and the second segmented test flow are independent from each other, so that flexible test arrangement can be performed according to actual situations, and it is ensured that local system functions are verified. However, the test conditions of the segmented test mode are different from those of the real accident condition, and the risk that the system function cannot be enveloped and verified under the accident condition exists.
In the sectional test mode, a diesel engine starting command is sent through a test button, and after the diesel engine is started successfully, the emergency bus switch 001JA is disconnected, the 002JA is switched on, and the diesel engine is switched to be loaded. In the whole starting process of the diesel engine, the LHA001JA of the emergency bus is always in a closing state, and the power supply of the control system, the excitation system and the auxiliary system is also supplied by the emergency bus. And in case of an accident, the emergency bus is in real power loss, a diesel engine starting command is sent, at the moment, the diesel engine is started under the condition that the emergency bus is in real power loss, the control system and the excitation system are powered by a 48-volt direct current storage battery and a 125-volt direct current storage battery, 380-volt alternating current is in a power loss state, and the condition is different from the working condition in the segmented test mode. For example, in the field, the problem that the excitation switch of the diesel engine cannot be closed due to a slightly low direct-current voltage under the condition of battery power supply has occurred, and the device problem cannot be found through the segmented test mode.
And if the target test mode is the complete test mode, directly disconnecting the external power switch of the emergency bus so as to carry out complete test on the process of starting the diesel engine when the emergency bus loses power under the condition that the emergency bus loses power.
Under the complete test mode, through the outer power switch 001JA of disconnection emergency bus, realize emergency bus true power loss, utilize the bus to lose the power signal and trigger the diesel engine start command, after the diesel engine starts successfully, switch 002JA combined floodgate to can be complete verify with the same power loss condition of accident operating mode under, the diesel engine loses 380V alternating current power supply at auxiliary assembly promptly, instrument accuse and excitation system rely on the starting ability under the battery condition, discover the latent fault that exists in the system and on the equipment in advance. Has important practical significance for the safe production of power stations.
And S203, evaluating the starting capability of the diesel engine power supply system according to the test result.
In the segmented test mode, the functions of a local system of the diesel engine power supply system can be evaluated according to the test result, and possible faults in the local system can be found in time; and under the complete test mode, the complete starting capability of the diesel engine power supply system can be evaluated according to the test result, and possible faults in the whole system can be found in time.
In summary, the method and the device for starting the diesel engine in case of power failure of the emergency bus acquire the test instruction for starting the diesel engine in case of power failure of the emergency bus, and determine the currently adopted target test mode according to the test instruction for starting the diesel engine in case of power failure of the emergency bus; executing the test flow of the diesel engine started by the power failure of the emergency bus corresponding to the target test mode to obtain a test result corresponding to the target test mode; and evaluating the starting capability of the diesel engine power supply system according to the test result. By the aid of the method, a set of complete diesel engine testing method is provided, faults possibly occurring in the starting process of the diesel engine can be found in time, and safety of the nuclear power station is greatly improved.
