基于 PSCAD 的 10 kV 母线电压异常故障分析

Analysis on Abnormal Voltage Fault of 10 kV Bus Based on PSCAD

摘要:

针对一起 110 kV 变电站 10 kV 母线电压异常故障的原因进行分析，通过模拟故障时的电网工况在 PSCAD 中 建立仿真模型进行分析，根据仿真结果可迅速找出故障原因，并针对 PASS 设备故障提出相应的解决方法，同时也为 今后查找解决其他类似的故障提供了经验。

Abstract:

The causes of an abnormal voltage fault on 10 kV bus in 110 kV substaion are analyzed，and the simulation model is established in PSCAD under fault condition of power grid． The causes of fault will be found out quickly based on the simulation results，and the corresponding solutions are proposed aiming at fault of PASS，which can provide experiences for solving other similar faults in the future．
