摘要
根据某背靠背换流站C型阻尼滤波器中电阻器故障而保护未动作的问题,分析了现有滤波器保护策略中存在的问题,根据电阻故障时的故障特征,提出了一种新的保护策略,并通过MATLAB仿真计算验证了该保护策略的正确性。
According to problem that relay protection does not function when there is a resistor failure in the Type-C damped filter in certain back-to-back converter station,the existing problems in the strategy of filter protection are analyzed.Based on the fault features of the resistance when there is a failure,a new protection strategy is proposed and the validity of the protection strategy is verified by the MATLAB simulation calculation.
