摘　　要：基于ADPSS,对500kV输电线路并联高抗的两个问题进行了仿真研究。即在进行线路投切以及线路上发生短路故障时,线路两端并接高抗对线路电流的影响。试验结果表明,500kV线路两段并接高抗后,当线路运行工况发生变化时,由于高抗与线路分布电容之间的能量交换,会在线路电流中产生高频谐波分量。In the paper,the two problems concerning 500kV transmission line with HV reactor are simulated based on ADPSS.When HV reactances connect parallelly on the two ends of transmission line,after transmission line is cut off or short circuit occurs,the influence of HV reactance on the current flowing transmission line is analyzed.From simulating results,when HV reactances connect parallelly on the two ends of transmission line,energy exchange will occur between HV reactance and transmission line distributed capacitance after the operating condition of transmission line changing,and high frequency harmonic component will occur in transmission line current.
