the DC filter isolation due to imbalance action of capacitor C1 occurred several times. In this paper
the imbalance protection action of DC filter capacitor C1 in recent three years are summarized
the typical event is analyzed
the corresponding correction measures and suggestions are proposed based on actual operation condition of the equipment so to improve the safe and stable operation level of DC filter capacitor for Xingan HVDC project and to provide reference for the HVDC transmission projects in the future.
