摘　　要：提出了由有源无功补偿结合固定并联滤波器应用于感性容性无功不对称的电气化铁道的方法,该方法既具有双向连续调节又具有节省投入无功发生器容量的优势。该补偿器结合PWM技术电流直接控制方法来控制逆变器的无功输入与输出,实时调节牵引变压器二次母线电压,克服了传统晶闸管控制电抗器的谐波问题,逆变器的工作容量仅为补偿容量的25%。最后通过仿真加以证明其可行性和有效性,并进行了经济比较分析。Proposed reactive power compensation by the active parallel combination of a fixed filter that applies to emotional - asymmetric capacitive reactive power electrified railway, both for Continuous two-way adjustment and Savings in the capacity of reactive power generator. The combination of PWM technology compensator current methods of direct control of the inverter to control reactive power input - output, real-time regulation of traction transformer secondary bus voltage. In addition, to overcome the traditional thyristor controlled reactor harmonic problems, the work of the capacity of the inverter capacity is only 25 percent of compensation. Finally, simulation to prove its feasibility and effectiveness, and comparative analysis of economic .
