标准范围

IEC TS 62910:2015（E）提供了一个测试程序，用于评估公用事业互连光伏系统中所用逆变器的低压穿越（LVRT）功能的性能。本技术规范最适用于光伏逆变器连接到公用高压配电系统的大型系统。然而，适用程序也可用于LVRT要求不断变化的地方的低压安装，例如单相或三相系统。测量程序设计为非标准-尽可能针对现场，以便在一个试验现场测量的LVRT特性在其他现场也可以被视为有效。本技术规范适用于光伏逆变器的测试，但其中包含的信息可能也有助于测试一个完整的光伏发电厂，该光伏发电厂由多个逆变器组成，这些逆变器在一个点连接到公用电网。进一步为电力互联光伏逆变器的数值模拟和模型验证提供了依据。

IEC TS 62910:2015(E) provides a test procedure for evaluating the performance of Low Voltage Ride-Through (LVRT) functions in inverters used in utility-interconnected PV systems. The technical specification is most applicable to large systems where PV inverters are connected to utility HV distribution systems. However, the applicable procedures may also be used for LV installations in locations where evolving LVRT requirements include such installations, e.g. single-phase or 3-phase systems. The measurement procedures are designed to be as non-site-specific as possible, so that LVRT characteristics measured at one test site, for example, can also be considered valid at other sites. This technical specification 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 inverter numerical simulation and model validation.
