IEC TS 62257-7-2:20 22适用于扫风面积小于或等于200 m2的所有小型风力涡轮机(SWT)，设计用于向IEC TS 62257-2中描述的系统中使用的隔离站点供电。 本文件不是小型风力涡轮机和风力发电系统的设计、安装、操作或维护的详尽资源，而是更侧重于提供可能影响农村电气化项目中小型风力发电系统（SWPS）使用的选择策略和标准的建议。 本文件的目的是为用户提供设备在其估计使用寿命期间的适当可靠性和安全性水平。

IEC TS 62257-7-2:2022 applies to all small wind turbines (SWTs) with a swept area smaller than or equal to 200 m², and designed for supplying electrical power to isolated sites used in systems as described in IEC TS 62257-2.
This document is not an exhaustive resource for the design, installation, operation or maintenance of small wind turbines and wind power systems, but is more focused on recommendations to provide strategies on selection and criteria which may affect the use of a small wind power system (SWPS) in a rural electrification project.
The aim of this document is to provide users with the appropriate levels of reliability and safety of the equipment during its estimated service lifespan.
