摘　　要：分析了晶闸管投切电容器TSC(ThyristorSwitchedCapacitor)系统的工作原理及产生晶闸管非全相导通故障的原因,主要有谐波干扰、电磁干扰、触发系统自身设计不合理三方面。提出了相应的防范措施,如可在触发脉冲形成前进行滤波,建立电磁兼容环境,调节元件参数等。这对提高配电系统的功率因数、稳定系统电压、降低网损具有积极的作用。The working principle of TSC(Thyristor Switched Capacitor)system is introduced.The causes of thyristor incomplete phase continuity are analyzed,in which the harmonic interference,electromagnetic interference and unreasonable design of trigger system are involved.Its countermea-sures are put forward,such as filtering before trigger pulse formed,setting up electromagnetic compatible environment,regulating element parameters,and so on,which helps to improve the power factor,stabilize system voltage and lower network loss of distribution system.
