摘    要:采用EMTDC软件建立了详细UHVDC模型,研究了交直流系统并列运行的相互影响,并对交流系统故障进行了仿真。仿真结果表明:逆变侧交流系统故障比整流侧交流系统故障更容易引起换相失败,三相系统故障造成严重的功率损失直至极退出停运,故障期间极控系统的策略有利于交流系统故障后,直流系统迅速恢复,合理的控制模式组合有助于故障后的恢复特性。

关 键 词:特高压直流输电    极控系统策略    双十二脉动换流器    交流故障

Abstract:This paper sets up a particular UHVDC model by using EMTDC software and researches the influence of AC/DC operating together,especially the simulation of AC fault.The results show that the AC fault at inverter is easier leading to communication fault than at rectifier.Three-phase fault will cause serious power losing even to blocking polar.The strategy of polar control is to help DC system recovery rapidly after AC fault.The proper control mode combination is useful to the recovery characteristic after AC f...
Keywords:ultra high voltage direct current  strategy of polar control  bipolar 12-pluse converter valves  AC fault
