标准摘要
[中文适用范围]： IEC 60364-7-712:2025适用于光伏系统的电气安装。光伏系统的设备，如同其他设备一样，仅涉及其在安装中的选择和应用部分。光伏安装包括从光伏组件到与其他安装部分（例如配电盘或供电点）连接点的所有设备。IEC 60364的本部分包括由于安装光伏供电系统而产生的电气安装要求。其中包括可能安装储能系统（例如电池）的相关要求。同时，还包含了适用于IEC 60364-8-82中描述的孤岛运行模式的光伏安装的要求。本版第三版取消并替代了2017年发布的第二版。本版为技术修订版。与前一版相比，本版包括以下重大技术变更：a）技术内容经过广泛修订和扩展，考虑了自第二版发布以来在光伏系统建设和运行中的经验以及技术的发展。b）主要变更包括对光伏发电厂的要求，直接连接到电池电路，引入直流母线电路和直流单元（DCUs）。 [外文原描述]： IEC 60364-7-712:2025 applies to electrical installations of PV systems. The equipment of a PV system, like any other item of equipment, is dealt with only so far as its selection and application in the installation is concerned. A PV installation comprises all equipment from PV modules(s) up to the connection point to other parts of the installation, for example a distribution board or the utility supply point (point of connection). This part of IEC 60364 includes requirements on electrical installation resulting from the installation of PV power supply installations. Requirements relating to the possible installation of energy storage systems (e.g. batteries) are included. Requirements are also included for PV installations for island mode operation described in IEC 60364-8-82. This third edition cancels and replaces the second edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The technical content has been extensively revised and expanded, taking into account experience gained in the construction and operation of PV installations, and developments made in technology, since the second edition was published. b) Key changes include requirements for PV power generation plants, direct connection to battery circuits, introduction of DC bus circuit and DCUs.
