直流输电整流器阀故障特征研究

摘要

在PSCAD/EMTDC环境下搭建仿真模型,研究了高压直流输电整流器的阀故障,仿真分析了整流站内部分别发生阀不开通和误开通故障的情况,并对故障引起的系统暂态过程和相应的控制策略进行了研究,得出有指导意义的结论。%This paper sets up simulation model under the PSCAD/EMTDC environment,studies the rectifier valve faults with HVDC transmission,simulates and analyzes error firing and non-firing condition at the rectifier station,and studies transient process owning to the faults and corresponding controlling strategies,and finally obtains some beneficial guiding conclusions.
