摘　　要：提出了用阻抗平衡法补偿电气化铁道负序电流和无功功率的原理,同时也提出了确定补偿器型式和容量的系统方法,用此方法计算出了用TCR并联电容法和变耦电抗法来实现了补偿时的电感和电容容量,从而可知TCR并联电容器法用于电气化铁道负序和无功补偿经济合理且易于实现。This paper introduces the theory of using the reactance equity to compensate negative order current and var of electrified railway,and at the same time presents the system method of confirming the type and capacity of compensating device. The capacity of inductance and the capacitance are worked out by TCR parallel connection of the capacitance with the adjusting coupling controlled reactance. It comes to the conclusion that TCR parallel connection is easy to realize and economically reasonable for negative order and var compensation of the electrified railway.
