摘要

提出了一种新颖的方案，利用具有反并联二极管和一个电阻器的晶闸管，以最小的浪涌电流在三角形连接电容器组中进行开关。电阻器仅向电容器提供初始充电电流，因此可以具有相当低的瓦数。广泛的仿真结果证明了该方案的合理性。仿真结果证实了电容器具有良好的无电流浪涌导通性能。

Surgeless switching of 3 phase delta connected capacitor banks in distribution systems

A novel scheme is presented by which thyristors with antiparallel diodes and one resistor will be sufficient to switch in a delta connected capacitor bank with minimum surge current. The resistor supplies only the initial charging current to the capacitors and hence can be of reasonably low wattage. Extensive simulation results are presented in justification of the scheme. The simulation results confirm the excellent current-surge-free switching-on of the capacitors.<>
