Abstract
IEC/IEEE 63332-387:2024,Nuclear facilities-Electrical power systems-Diesel generator units applied as standby power sources,was released in September 2024,which defines the application and testing of diesel generator(DG)units used as standby power supplies in nuclear facilities.This standard applies to DG units related to electrical equipment for safety in accordance with terminologies of International Atomic Energy Agency(IAEA)including all equipment important to safety in accordance with IEEE classification scheme.NB/T 20485-2018RK,The design and test requirements for emergency diesel-generator units in nuclear power plants,defines the design and testing requirements for emergency diesel generator units in nuclear power plants,which was reviewed and approved by the National Nuclear Safety Administration on October 25,2017.To implement the National Nuclear Safety Administration's requirements for benchmarking against international first-class standards and enhancing the reliability of diesel generators,this paper analyzes the differences in periodic testing between IEC/IEEE 63332-387:2024 and NB/T 20485-2018RK to provide references for the subsequent revision of relevant standards.关键词
