IEC 60143-4:20 23规定了与传输线串联使用的晶闸管控制串联电容器(TCSC)装置的测试。本文件还讨论了考虑TCSC晶闸管阀组件、电容器和电抗器的额定值以及TCSC控制特性、保护特性、冷却系统和系统运行的问题。 IEC 60143-4:20 23取消并取代了2010年发布的第一版。本版构成技术修订版。 与上一版相比，此版本包括以下重大技术变更: a)晶闸管阀试验要求参照IEC 62823； b)修正了第4.2款中的公式(1)； c)硬件在环（HIL）测试，子条款7.5.4，用网络模拟器代替先前规定的实时保护和控制系统测试。

IEC 60143-4:2023 specifies the testing of thyristor controlled series capacitor (TCSC) installations used in series with transmission lines. This document also addresses issues that consider ratings for TCSC thyristor valve assemblies, capacitors, and reactors as well as TCSC control characteristics, protective features, cooling system and system operation.
IEC 60143-4:2023 cancels and replaces the first edition published in 2010. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous edition:
a) thyristor valve testing requirements refer to IEC 62823;
b) Formula (1) in Subclause 4.2 has been corrected;
c) Hardware-in-the-loop (HIL) tests, Subclause 7.5.4, replaces previously specified real time protection and control system test with network simulator.
