直流输电系统紧急停运方式对系统过电压的影响（Influence of the ESOF Strategy on HVDC System Overvoltage）
紧急停机 移相 旁通对 直流输电系统 过电压
2010/8/17
基于云广±800 kV特高压直流输电工程的参数，研究了直流输电系统在最高电位换流变阀侧对地故障、逆变站闭锁而旁通对未解锁、逆变站交流电源丢失等三种故障工况下紧急停运方式对系统暂态过电压的影响，紧急停运方式包括移相、投旁通对闭锁和直接闭锁。分析结果表明，对于整流站换流变阀侧以及直流线路故障而言，采取故障后移相方式与直接闭锁相比可以更好地降低阀上的过电压；对于逆变站意外闭锁类型的故障，整流站5 ms内...
