标准摘要
[中文适用范围]： IEC 63349-1:2025 规定了光伏直驱设备（PVDDA）控制器的控制功能和运行性能要求。PVDDA控制器是一种用于控制电源（如光伏阵列、电网、储能装置等）与设备（如空调、冰箱、水泵等）之间电力分配的装置。PVDDA控制器的要求适用于电压不超过1 500V直流或1 000V交流的系统。PVDDA控制器的安全性和电磁兼容性（EMC）要求尚在考虑中，本文件不涵盖这些内容。与PVDDA控制器连接的功率转换器的安全要求如下：- 连接到光伏阵列的转换器，适用IEC 62109-1和IEC 62109-2；- 连接到电网的双向转换器，适用IEC 62909-1和IEC 62909-2；- 连接到储能装置的转换器，适用IEC 62477-1和IEC 62509；- 变频驱动器，适用IEC 61800-5-1。连接到PVDDA控制器的每个单独功率转换器的性能要求参考IEC 62093。 [外文原描述]： IEC 63349-1:2025 establishes control functions and operational performance requirements for photovoltaic direct-driven appliance (PVDDA) controllers. PVDDA controllers are devices used for controlling power among power sources (such as a PV array, grid, energy storage, etc.) and appliances (such as an air-conditioner, refrigerator, water pump, etc.). The requirements for PVDDA controllers are applicable to systems with voltages not higher than 1 500V DC or 1 000V AC. Safety and EMC requirements for the PVDDA controllers are under consideration and not covered by this document. Safety requirements for power converters connected to a PVDDA controller are listed as follows: - for converter connected to PV array, IEC 62109‑1 and IEC 62109‑2 are applicable; - for bi-directional converter connected to grid, IEC 62909‑1 and IEC 62909‑2 are applicable; - for converter connected to energy storage, IEC 62477‑1 and IEC 62509 are applicable; - for variable frequency drive, IEC 61800-5-1 is applicable. Performance requirements for each individual power converter connected to a PVDDA controller refer to IEC 62093.
