IEC/IEEE 63332-387:2024定义了在核设施中用作安全级备用电源的柴油发电机组(DG)的应用和测试标准。一般而言，该标准适用于新建核设施以及现有设施的升级或改造。现有设施可以自愿采用这些要求，以增强已安装DG机组的性能能力和可靠性。该标准可用于需要高度可靠的现场交流(AC)电源的应用，以在发生可能长时间失去场外电力的事件后维持工厂安全。 本文件提供了单个DG机组的主要设计标准、设计特点、测试和鉴定要求，使其能够在电厂安全分析中编目的设计基础事件产生的条件下满足作为备用电源一部分的功能要求s.

IEC/IEEE 63332-387:2024 defines the criteria for the application and testing of diesel generator (DG) units used as safety class standby power supplies in nuclear facilities. In general, the standard applies to new nuclear facilities as well as for upgrading or back-fitting of existing facilities. Existing facilities can voluntarily adopt the requirements to enhance the performance capabilities and reliability of the installed DG units. The standard can be used in applications where highly reliable onsite alternating current (AC) power source is required to maintain plant safety following an event with potential loss of offsite power for an extended duration.
This document provides the principal design criteria, the design features, testing, and qualification requirements for the individual DG units that enable them to meet their functional requirements as a part of the standby power supply under the conditions produced by the design basis events catalogued in the plant safety analysis.
