摘要
以500kV变电站实际参数为基础,建立ATP/EMTP仿真模型,计算了变压器加装小电抗后中性点及中压侧的过电压水平,结合需要限制的短路电流,确定了小电抗的具体参数。
Based on the actual parameters of 500kV substation, the ATP/EMTP simulation model is established. The over-voltage level of the neutral point and medium voltage side is simulated and calculated after installation small reactors. The specific parameters of small reactors are determined combined with the limit size of short-circuit current.
