摘　　要：本文介绍了一种不同于传统抗器的新型的电抗器——变耦式可控电抗器,此电抗器是通过改变互感器的耦合系数来独立调节线路电抗。文章分析了可控电抗器的电抗特性,并从绕组电势构成的观点详尽讨论了可控电抗的控制原理。用PSCAD/EMTDC仿真软件搭建模型进行模拟实验,通过对理论研究与仿真结果的比较以及谐波的分析,验证了其电抗的可控性以及该仿真模型的正确性、有效性。This paper introduces a novel reactance which is different from tradional reactance-Thyristor controlled reactance series compensation by adjustable coupling, Which can regulate the line reactance independently fast by change the coupling of inductance. The characteristic of controlled reactor is analyzed, through the analysis on e.m.f of the winding, the control mechanism of controlled reactance is researched in detail. The PSCAD/EMTDC emulator is utilized to build the model,through the comparison between ...
