To improve the accuracy and efficiency of diagnosis when a converter fails, an active current limiting method is applied to realize the converter fault diagnosis in a power system. Active current limiting control is used to limit the output DC current from the converter to 1.2 times of rated current and limit the fault current, thus improving the stability of fault diagnosis. Based on a prediction model, the fault current distribution characteristics of the converter in the power system are diagnosed, and the bridge arm current is taken as the diagnosis parameter. The difference between the measured bridge arm current and predicted value is compared. If the difference is greater than the threshold value, it is judged that the converter has a fault. Experimental results show that the proposed method had a high accuracy and a high diagnosis efficiency in diagnosing the converter faults in an experimental power system, and the rates of false diagnosis and missed diagnosis were low, indicating that the converter diagnosis effect was satisfying.

为提高电力系统换流器故障的诊断效率与准确性,应用主动限流方法实现换流器故障诊断。使用主动限流控制将换流器输出直流电流限制在1.2倍额定电流附近,限制故障电流,提高故障诊断的稳定性;基于预测模型诊断电力系统换流器故障电流分布特征,将桥臂电流作为诊断参数,对比桥臂电流测量值与预测值之间的差值,若差值大于阈值,则判定诊断出换流器存在故障;实验结果表明,使用该方法诊断电力系统换流器故障时,具有较高准确率与诊断效率,且误诊断与漏诊断率较低,具有良好的换流器诊断效果。
