摘　　要：随着电力系统网架不断增强,局部煤炭基地装机规模不断增加,系统短路电流也不断攀升,为解决短路电流超标问题,一般采用加装串联电抗器抑制短路电流。以新疆五彩湾地区短路电流问题为例,对系统加装串联电抗器前后的无功电压、短路电流情况进行了对比分析;仿真结果表明,加装串联电抗器对抑制短路电流效果明显,但对系统无功电压产生较大影响,为此提出了优化加装串联电抗器的措施意见,为后续串联电抗器的实施提供了参考依据。With the grid frame of power system is strengthening , the size of local coal base is increasing and the short -circuit current of system is also rising , adding series reactors is usually adopted to suppress short -circuit current in order to solve the problem.Taking the short-circuit current in Xinjiang WuCaiwan area for example , the reactive voltage and short -circuit current are compared and analyzed before and after adding series reactors .The simulation results show that adding series reac-tors has a definite improvement in suppressing the short -circuit current , but it also has a great influence on system reactive voltage .So the suggestions are proposed to optimize the measures by adding series reactors , which can provide a reference for the following implementation of adding series reactors .
