【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、过电流间的关系曲线和不同运行条件下电抗器的最佳取值并提出了采用了可调电抗器和根据系统具体运行条件调节电抗率的建议
【Abstract】 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.
【Key words】 reactive compensation capacitors; series reactors; harmonics amplification; inrush current;
