摘要
晶闸管控制单元(TCU)是高压直流换流阀设备的核心部件,工作时需从换流阀主回路获取能量。在简要介绍TCU取能电路工作原理的基础上,应用仿真方法,分析了换流阀闭锁、整流和逆变运行及遭受电压冲击情况下,TCU取能电路的工作特性。根据分析结果可知,目前的TCU取能电路设计,可满足换流阀各类工况下的应用要求。
The thyristor control unit（TCU）,as an indispensable part of high voltage direct current converter valves, needs to obtain energy from the main circuit of the converter valve.The design and the principle of the TCU energy storage circuit are briefly introduced, and the working characteristics of the circuit are also analyzed by using the simulation method in different operation conditions of the converter valve, including the mode of blocking, rectifier,inverter,and suffering from high voltage surges.The results show that the design of the TCU energy circuit can meet the application requirements of the converter valve.
