摘要
串补装置一般安装于超高压输电线路中间,其运行状况将影响到整条线路的工作状态,因而在串补上加装一些保护设备。使用EMTP软件建立串补装置接输电线路模型,模拟线路两端开关动作时,串补保护装置的动作情况,根据仿真输出波形,分析线路开关动作时,串补保护装置误动作的原因,并提出改进措施。
Compensation series is installed in the middle of EHV transmission line and its operation condition will ＇affects the condition of the line. Protection equipment is installed on the compensation series. EMTP program is used to make models of compensation series and transmission lines, simulating the action of compensation series protection when line switches act. The paper analyzes the reason to the wrong action of protections according to waveforms and improvement measures are proposed.
