摘要
通过短路电流计算,分析了主变中性点加装不同参数小电抗对短路电流的影响,并考虑了区域特性以及电网发展,提出了华东电网500 kV主变中性点小电抗的合适参数。
By calculating the short-circuit current under different value of small reactance,the influence of neutral point grounding with small reactance to short circuit current is discussed.Considering the different character and development of the power grid,the most suitable impedance value of small reactor in East China Power Grid is proposed.
