标准摘要
[中文适用范围]： 本部分IEC 61724阐述了光伏（PV）系统性能监测和分析的术语、设备和方法。它涉及监测设备的传感器、安装和准确性，以及测量参数的数据采集、质量检查计算参数和性能指标。它还作为其他依赖于收集数据的标准的基础。 [外文原描述]： IEC 61724-1:2021 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 61724-1:2021 outlines terminology, equipment, and methods for performance monitoring and analysis of photovoltaic (PV) systems. It also serves as a basis for other standards which rely upon the data collected. This document defines classes of photovoltaic (PV) performance monitoring systems and serves as guidance for monitoring system choices. This second edition cancels and replaces the first edition, published in 2017. This edition includes the following significant technical changes with respect to the previous edition: - Monitoring of bifacial systems is introduced. - Irradiance sensor requirements are updated. - Soiling measurement is updated based on new technology. - Class C monitoring systems are eliminated. - Various requirements, recommendations and explanatory notes are updated.
