本推荐规程旨在定义用于发电站服务的低压不间断电源（UPS）系统的应用和性能要求。本推荐规程仅针对具有直流电能存储能力的半导体交-交转换器系统（静态）的要求。本推荐规程不适用于其他类型的UPS系统。本推荐规程旨在涵盖应用要求，如负载信息和使用条件、性能要求和设计、带或不带整流器/充电器的逆变器的常规测试要求，以及仅限转换开关。 电池和电池充电器的应用要求不包括在本推荐规程中。它们可以在其他文件中找到。本推荐规程不适用于设备或部件设计要求、安全相关设计标准或设备鉴定和运行前/监督测试要求。

This recommended practice is intended to define the application and performance requirements for a low-voltage uninterruptible power supply (UPS) system used for service in power generating stations. This recommended practice addresses only requirements for semiconductor ac to ac converter systems (static) with dc electric energy storage capability. This recommended practice is not intended to address other types of UPS systems. This recommended practice is intended to cover application requirements, such as load information and service conditions, performance requirements and design, routine testing requirements for inverters with or without rectifier/chargers, and transfer switches only. The application requirements for batteries and battery chargers are excluded from this recommended practice. They can be found in other documents. This recommended practice is not intended to address equipment or component design requirements, safety-related design criteria, or requirements for equipment qualification and preoperational/surveillance testing.
