IEC TS 63217:2021提供了评估公用事业互连光伏(PV)系统中使用的逆变器过电压穿越(OVRT)功能性能的测试程序。 本文件最适用于光伏逆变器连接到公用事业高压（HV）配电系统的大型系统。然而，适用的程序也可以用于在不断发展的OVRT要求包括低压(LV)装置的位置中的低压(LV)装置，例如单相或三相系统。本文档用于测试光伏逆变器，尽管它包含的信息也可能有助于测试由在单点连接到公用电网的多个逆变器组成的完整光伏发电厂。它进一步为公用事业互联光伏逆变器的数值模拟和模型验证提供了基础。

IEC TS 63217:2021 provides a test procedure for evaluating the performance of Over Voltage Ride-Through (OVRT) functions in inverters used in utility-interconnected photovoltaic (PV) systems.
This document is most applicable to large systems where PV inverters are connected to utility high voltage (HV) distribution systems. However, the applicable procedures may also be used for low voltage (LV) installations in locations where evolving OVRT requirements include such installations, e.g. single-phase or 3-phase systems. This document is for testing of PV inverters, though it contains information that may also be useful for testing of a complete PV power plant consisting of multiple inverters connected at a single point to the utility grid. It further provides a basis for utility-interconnected PV inverters numerical simulation and model validation.
