本文件规定了用于往复式内燃机（RIC）发动机驱动发电机组应用时，在励磁控制系统控制下的交流发电机的主要特性，并补充了IEC 60034-1中给出的要求。它涵盖了此类交流发电机在陆地和海上应用的使用，不包括用于飞机或驱动陆地车辆和机车的发电机组。 注:对于某些特定应用（如基本医院用品、高层建筑、与电网平行运行），可能需要补充要求。 本文件的规定可被视为制定任何补充要求的依据。 对于由其他往复式原动机（如蒸汽机）驱动的交流发电机组，本文件的规定可作为确定这些要求的基础。

This document specifies the principal characteristics of alternating current (a.c.) generators under the control of their excitation control system when used for reciprocating internal combustion (RIC) engine driven generating set applications and supplements the requirements given in IEC 60034-1. It covers the use of such a.c. generators for land and marine applications, excluding generating sets used on aircraft or to propel land vehicles and locomotives. NOTE For some specific applications (e.g. essential hospital supplies, high-rise buildings, operation parallel with the grid), supplementary requirements can be necessary. The provisions of this document can be regarded as the basis for establishing any supplementary requirements. For a.c. generating sets driven by other reciprocating-type prime movers (e.g. steam engines) the provisions of this document can be used as basis for establishing these requirements.
