摘　　要：为合理选取无功补偿电容器组串联电抗器的电抗率 ,使电容器组安全经济地运行 ,结合电路分析与ATP—EMTP程序仿真计算研究了电抗率对电容器组上合闸过电流、分闸过电流、高次谐波过电流以及合闸过电压、重燃过电压等的影响 ,得到电抗率大小与上述各种过电压。In order to select reactance ratio of series reactors in reactive compensation capacitors bank properly to ensure safety of the capacitors, by methods of circuit analysis and ATP-EMTP simulation, the influences of reactance ratio on switching inrush current, high frequency harmonics over current, switching inrush voltage, and re-fire overvoltage etc. is calculated and analyzed The relevant curves between reactance ratio and the inrush currents/inrush voltages mentioned above are given. The optimum ratio is determined under various operation conditions. A proposal is made for application of adjustable reactors, therefore it is possible to regulate the reactance ratio in accordance with actual operation conditions.
