标准摘要
[中文适用范围]： 本部分IEC 62257的目的是规定分散式农村电气化系统中发电机（最大功率=100 kVA）的一般要求。目的是指出在选择、确定尺寸、安装、操作和维护该设备时必须考虑的主要项目。本部分IEC 62257规定了分散式农村电气化系统中发电机的一般要求。本文档是一个一般性介绍，随后是针对农村电气化项目中最常用的发电技术的更具体的文档。 [外文原描述]： IEC TS 62257-7:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62257-7:2017 specifies the general requirements for the generators in decentralized rural electrification systems. This document is a general introduction followed by more specific documents dedicated to the generation technologies which are the most currently used in rural electrification projects. This new edition includes the following significant technical changes with respect to the previous edition: removed the word "small" from the description of the PV systems, and removed the power limit (100 kVA); increased the relevant voltage levels to 1 000 V (AC) and 1 500 V (DC).
