摘要

针对某直流滤波器差动保护报警事件，通过分析滤波器保护的暂态故障和稳态运行波形，结合滤波器CT的结构和采样原理，逐一排除产生保护报警的原因。最后找到一次设备的分路，定位故障点，为直流滤波器开展维护工作提供依据。

Abnormal analysis of DC filter differential protection in converter station

Aiming at a DC filter differential protection alarm event, by analyzing the waveform of transient fault and steady-state operation of the filter protection, combining with the structure and sampling principle of the filter CT, the reasons causing the protection alarm are eliminated one by one. Finally, the shunt path of the primary equipment is found and the fault points are located, which provides the basis for the DC filter to carry out maintenance work.
