Abstract:

The valve cooling system of convertor station is the important support for the safe and reliable operation of converter valve. The Suidong converter station alarming accident is caused by the high temperature of the water from the valve cooling system, which originates from the instantaneous voltage lostof the cooling system. In this paper, the accident is analyzed and the solution is also given. The operation results show that the solution is feasible and effective.
