摘要:
在电抗器副边设置多个绕组,分别连接双向晶闸管与电压源型逆变器,通过对晶闸管分级投切与逆变器控制完成电抗的大范围连续调节。将该电抗器与固定电容器支路并联运行,可根据动态负荷自动调节牵引变电站的无功功率,提高功率因数。仿真与试验证明:该可控电抗器具有响应速度快、补偿精度高、谐波输出低等优异性能。
Abstract:
A multi-winding reactor, the secondary windings of which connecting anti-parallel thyristors and voltage- source inverter (VSI) respectively, can obtain reactance varying in a wide range continuously with the thyristors′ stepping switching and VSI controlling. With parallel operation of the controllable reactor and fixed capacitor branches, reactive power of traction substations can be regulated automatically according to dynamic loading for increasing power factor. Simulating and experimental results validate the advantages of the presented reactor such as fast response, high compensating precision and low harmonic output etc.
