本文件规定了往复式内燃机和交流发电机作为一个单元运行时产生的设计和性能标准。该装置是否可以与电网并联运行。 本文件适用于由陆上和海上RIC发动机驱动的交流发电机组，不包括用于飞机或推进陆地车辆和机车的发电机组。 对于某些特定应用（例如基本医院用品和高层建筑），可以适用补充要求。本文件的规定是制定任何补充要求的基础。 对于由其他往复式原动机（如蒸汽机）驱动的发电机组，本文件的规定可作为确定这些要求的基础。

This document specifies design and performance criteria arising out of the combination of a reciprocating internal combustion (RIC) engine and an alternating current (AC) generator when operating as a unit. This unit can run in parallel to the grid or not. This document applies to AC generating sets driven by RIC engines for land and marine use, excluding generating sets used on aircraft, or to propel land vehicles and locomotives. For some specific applications (e.g. essential hospital supplies and high-rise buildings), supplementary requirements can apply. The provisions of this document are a basis for establishing any supplementary requirements. For generating sets driven by other reciprocating-type prime movers (e.g. steam engines), the provisions of this document can be used as a basis for establishing these requirements.
