晶闸管控制串联电容器（TCSC）是一种商用的柔性交流输电系统（FACTS）器件，用于对输电在线阻抗进行可控补偿，从而实现对输电在线潮流的控制。门控串联电容器（GCSC）是一种基于一对栅极换向开关与电容器并联的FACTS器件，它还可以控制传输线的阻抗和功率流。本文表明，在许多必须安装可控串联补偿器的情况下，可以使用GCSC代替TCSC，并且可能具有一些优势。对TCSC和GCSC组件的尺寸进行了比较。结果表明，GCSC中的电容器比TCSC中的电容器具有更低的兆伏安，特别是在功率流控制应用中。此外，还表明TCSC中的晶闸管阀需要具有比GCSC中的栅极换向开关阀更高的额定电流。
The thyristor-controlled series capacitor (TCSC) is a commercially available flexible AC transmission system (FACTS) device developed for controlled compensation of transmission-line impedance, which consequently leads to the control of transmission-line power flow. The gate-controlled series capacitor (GCSC), a FACTS device based on a pair of gate-commutated switches in parallel with a capacitor, can also control impedance and power flow of transmission lines. Here, it is shown that in many situations where a controllable series compensator must be installed, the GCSC may be used instead of the TCSC, possibly with some advantages. A comparison of the sizing of the TCSC and the GCSC components is presented. It is shown that the capacitor in the GCSC can have lower megavolt-amperes than in the TCSC, especially for power-flow control applications. Also, it is shown that the thyristor valve in the TCSC needs to have a higher current rating than the gate-commutated switch valve in the GCSC.
