Abstract
A DC line fault in its bipolar ground mode leads to DC filter protection malfunction in Jin guan convert station.According to the fault waveform, the fault reason was pointed out.The unreasonable design of DC filter protection leads to ratio differential protection of DC filter in non-protection area.Finally, the optimization suggestions were given.关键词
