本推荐规程描述了定义发电站或变电站直流负载的方法，以及确定铅蓄电池大小以提供该负载的方法。提供了一些与细胞选择有关的因素以供考虑。安装、维护、鉴定、测试程序以及对除铅蓄电池以外的电池类型的考虑超出了本推荐规程的范围。直流系统的设计和电池充电器的尺寸也超出了本推荐规程的范围。

This recommended practice describes methods for defining the dc load in a generating station or a substation and for sizing a lead storage battery to supply that load. Some factors relating to cell selection are provided for consideration. Installation, maintenance, qualification, testing procedures, and consideration of battery types other than lead storage are beyond the scope of this recommended practice. Design of the dc system and sizing of the battery charger(s) are also beyond the scope of this recommended practice.
