IEC TS 62910:2020 RLV包含官方IEC国际标准及其红线版本。红线版本不是官方文件，仅提供英文版本，并为您提供了一种快速简便的方法来比较官方IEC标准与其之前版本之间的所有更改。 IEC TS 62910:2020提供了一种测试程序，用于评估电力互联光伏（PV）系统中所用逆变器的欠压穿越（UVRT）功能的性能。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，适用程序也可用于低压（LV）安装，这些安装位于不断变化的UVRT要求包括此类安装的位置，例如单相或三相系统。评估的UVRT性能仅对被测逆变器的特定配置和运行模式有效。其他工厂或用户可设置配置中的逆变器需要单独评估，因为这些可能会导致逆变器UVRT响应表现不同。第二版取消并取代了2015年发布的第一版，构成技术修订版。

IEC TS 62910:2020 RLV contains both the official IEC International Standard and its Redline version. The Redline version is not an official document, it is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TS 62910:2020 provides a test procedure for evaluating the performance of Under Voltage Ride-Through (UVRT) 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 UVRT requirements include such installations, e.g. single-phase or 3-phase systems. The assessed UVRT performance is valid only for the specific configuration and operational mode of the inverter under test. Separate assessment is required for the inverter in other factory or user-settable configurations, as these may cause the inverter UVRT response to behave differently. This second edition cancels and replaces the first edition issued in 2015 and constitutes a technical revision.
