【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。更多还原

【Abstract】 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 Wu Caiwan 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 reactors 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.更多还原
