为了提高传统磁阀式可控电抗器在调节过程中的响应时间速度,研究能够实现提升传统磁阀式可控电抗器响应速度的拓扑结构,该拓扑结构通过先串后并的绕组接线方式,使磁阀式可控电抗器绕组回路不再存在削弱励磁电流的环流。仿真结果证明,新型磁阀式可控电抗器拓扑结构,能够承担电网电压快速无功输出的任务,缩短了响应时间,提高了电网的稳定性、安全性和运行效率,有利于维持电网系统不间断、稳定的运行。

In order to improve the response time speed of the traditional magnetic valve type controllable reactor in the regulation process, this paper presents a topology structure which can improve the response speed of the traditional magnetic valve type controllable reactor, the circuit of the magnetic valve type controllable reactor no longer has the circulating current which can weaken the excitation current through the winding connection mode of first series and then parallel, it can take on the task of fast reactive power output, shorten the response time, improve the stability, security and efficiency of the power grid, and help to maintain the uninterrupted and stable operation of the power grid system.
