本文对静止无功补偿器(SVC)中晶闸管控制电抗器(TCR)与晶闸管投切电容器(TSC)的接线方式进行分析,主要对比了6脉波接线与12脉波接线TCR的区别以及TSC三角形角内接线与角外接线方式下晶闸管与电容器的电压与电流定额.在无功补偿等值电纳的计算中,为了避免瞬时无功功率理论中的Clark变换,采用FBD(fryze-buchholz-dpenbrock)法提高计算速度,并搭建Matlab/Simulink模型进行仿真,验证其正确性.%In this paper,the wiring method of the thyristor controlled reactor (TCR) and the thyristor switched capacitor (TSC) in the static var compensator (SVC) is analyzed. The difference between 6-pulse and 12-pulse TCR wiring is mainly compared and the voltage and current of the thyristor and the capacitor at inner wiring and outer wiring of TSC triangle is also compared. In the calculation of equivalent susceptance of reactive power compensation,the FBD method is adopted to avoid Clark transform in the instantaneous reactive power theory and to improve calculation speed. The Matlab/Simulink model is set up for simulation and correctness verification.
