标准摘要
[中文适用范围]： IEC 61643 的这一部分描述了用于电压高达 1 500 V DC 的光伏 (PV) 系统以及额定电压高达 1 000 V rms 50/60 的光伏系统交流侧的 SPD 的选择、安装和协调原则Hz 光伏装置从光伏阵列或一组互连的光伏模块延伸到包括相关的布线和保护装置以及逆变器，一直到配电板或公用电源点中的连接点 IEC 61643 的这一部分考虑了所使用的 SPD位于不同地点和不同类型的光伏系统 位于建筑物顶部的光伏系统 位于地面的光伏系统，类似于自由场发电厂，其特点是多重接地和网状接地系统 术语光伏安装用于指代这两种类型光伏系统。术语“光伏电站”仅用于位于地面的扩展自由场多接地电力系统 对于包括电池在内的光伏装置，可能需要附加要求 注 1 IEC 60364 系列@ IEC 62305 系列和 IEC 61643-12 也适用 注 2该标准仅涉及SPD，不涉及设备内部集成的浪涌保护组件（例如逆变器@（PCE）功率转换设备） [外文原描述]： IEC 61643-32:2017 describes the principles for selection, installation and coordination of SPDs intended for use in Photovoltaic (PV) systems up to 1 500 V DC and for the AC side of the PV system rated up to 1 000 V rms 50/60 Hz. The photovoltaic installation extends from a PV array or a set of interconnected PV-modules to include the associated cabling and protective devices and the inverter up to the connection point in the distribution board or the utility supply point. This part of IEC 61643 considers SPDs used in different locations and in different kinds of PV systems:PV systems located on the top of a building. PV systems located on the ground like free field power plants characterized by multiple earthing and a meshed earthing system. The term PV installation is used to refer to both kinds of PV systems. The term PV power plant is only used for extended free-field multi-earthed power systems located on the ground. For PV installations including batteries additional requirements may be necessary. The contents of the corrigendum of June 2019 have been included in this copy.
