农村电气化用可再生能源和混合系统第9-6部分:集成系统光伏独立电气化系统（PV-IES）的选择建议

[中文适用范围]： 本部分IEC 62257的目的是提出简单的选择程序和廉价的比较测试，可以在发展中国家的实验室进行，以便从提交测试的多个产品中确定最适合特定农村电气化项目的个体光伏电气化系统（PV-IES）型号，功率不超过500 Wp。 它与IEC 62124的范围不同，后者是关于光伏（PV）独立系统的设计验证，提供了验证独立光伏系统设计的指导以及室内外测试，以评估包括光伏发电机、电池存储和负载（如灯、电视机和冰箱）在内的光伏系统的性能。 本文档提供的测试允许根据项目的通用规范（GS）要求评估PV-IES的性能，并验证其提供所需服务的能力。这些测试应在当地进行，尽可能接近实际现场操作条件。 本文档不是型式批准标准。它是一个技术规范，用作指南，并不替代任何现有的关于光伏系统的IEC标准。 [外文原描述]： IEC TS 62257-9-6:2019 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 62257-9-6:2019 proposes a simple selection procedure and cheap, comparative tests which can be performed in laboratories of developing countries, in order to identify the most suitable model of small Photovoltaic Individual Electrification Systems (PV- IES) up to 500 Wp for a particular rural electrification project from a number of products submitted for test. The tests provided in IEC TS 62257-9-6 allow assessment of the performance of a PV-IES according to the requirement of the general specification of the project (see IEC/TS 62257-2) and to verify their ability to provide the required service. This second edition of IEC TS 62257-9-6 cancels and replaces the first edition published in 2008. The main technical changes with respect to the previous edition are as follows: - Removal of the term "small" from the title of the publication and from description of rural electrification systems. - Removal of the limits on system voltage and power; these recommendations apply to systems of all sizes.
