摘要(Abstract):

特高压换流站设备类型多,设备故障概率高,因此如何快速可靠地实现故障定位对于故障处置具有重大意义。基于保护动作的结果,提出了一种基于保护分区特性的故障诊断方法,结合保护动作情况和动作保护的分区特性实现故障诊断。以金华换流站某日发生的换流变阀侧套管故障为例,使用文中提出的分区方法,实际应用结果表明,该方法准确地实现了故障定位和诊断。
There are various types of equipment in Ultra-high voltage converter stations and frequent faults.Therefore, reliable and fast fault location is of significance to fault treatment. Based on the result of the protection action, a fault diagnosis method based on the protection partition feature was proposed. The fault diagnosis combines the protection action situation and the partition feature of the protection. The aforementioned method is applied in the fault of the converter valve sleeve in Jinhua Station as an example. The practical application results show that the method can accurately achieved fault location and diagnosis.
