往复式内燃交流发电机组 第2部分:发动机

[中文适用范围]： 本文件规定了往复内燃机（RIC）用于交流发电机组应用时的主要特性。 它适用于陆地和海上使用的交流发电机组用的往复内燃机，但不适用于安装在飞机上或用于推进陆地车辆和机车的发电机组。 对于一些特定应用（例如医院基本供电、高层建筑），可能需要补充要求。本文件的条款可视为建立任何补充要求的基础。 定义了适用于往复内燃机驱动交流发电机使用的速度调节和速度特性的术语，并进行了说明。 对于其他往复式原动机（例如蒸汽机），本文件的条款可作为建立这些要求的基础。 [外文原描述]： This document specifies the principal characteristics of Reciprocating Internal Combustion (RIC) engines when used for alternating current (a.c.) generating set applications. It applies to RIC engines for a.c. generating sets 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, high rise buildings), supplementary requirements can be necessary. The provisions of this document can be regarded as the basis for establishing any supplementary requirements. The terms which define the speed governing and speed characteristics of RIC engines are listed and explained where they apply specifically to the use of the engine for driving a.c. generators. For other reciprocating-type prime movers (e.g. steam engines), the provisions of this document can be used as a basis for establishing these requirements.
