摘要
针对励磁涌流引起电网电压畸变并造成高压直流输电系统换相失败的问题,以交流电压总谐波畸变率作为指标评估换相失败风险,提出了具体的预测方法以及预防后续换相失败的控制策略,并通过仿真验证了该预测及控制方法的有效性。
In this paper,grid voltage distortion and commutation failure of HVDC transmission system caused by magnetizing inrush current are studied.Commutation failure is evaluated by using total harmonic distortion rate of AC voltage.Prediction method and control strategy for preventing subsequent commutation failure are proposed.Simulation is made to verify effect of the prediction and control method.
