[0003] However, at present, relevant technical standards such as "DL / T 5294-2013 Thermal Power Construction Engineering Unit Commissioning Technical Specifications" and other relevant technical standards have not clearly stated the specific methods and evaluation standards for the on-load test of diesel generators in the security power system. After the power supply of the system loses power and switches to a diesel generator, the diesel generator fails under load, which poses a great hidden danger to the safe shutdown of the power plant

The invention discloses a method for carrying out an on-load test on a diesel generator of a security power supply system of a power plant. The security power supply system comprises a security section working transformer, a security section working inlet wire switch, a security section bus, a diesel generator, a security section standby inlet wire switch, a security section load and a spare power automatic switching device. The security section working transformer is connected with the security section bus through the security section working inlet wire switch, and the diesel generator is connected with the security section bus through the security section standby inlet wire switch. The security section bus is connected with the security section load; and the spare power automatic switching device is connected with a control end of the security section working inlet wire switch and a control end of the security section standby inlet wire switch. According to the method, the on-load test of the diesel generator of the security power supply system of the power plant can be completed, and the safety and reliability of the operation of the security power supply system are improved.
Description
technical field [0001] The invention belongs to the technical field of electric power debugging and electric power test, and relates to a method for carrying out a load test of a diesel generator in a security power supply system of a power plant. Background technique [0002] The power supply object of the diesel generator set as the safety power source in the power plant is the accident safety load. The definition of the accident safety load in "DL / T 5153-2014 Thermal Power Plant Power Design Technical Regulations" is: in the event of a power failure of the whole plant or a unit unit When the factory power is lost, in order to ensure the safe shutdown of the furnace, it can be restarted quickly afterwards, or in order to prevent personal safety and other reasons, it is necessary to continue to supply power during the power outage. In practical application, since diesel generators are rarely used and are in a static state for a long time, diesel generators often have startu...
