摘要(Abstract)：

对门级控制串联电容器(gate-controlled seriescapacitor,GCSC)在抑制电力系统次同步谐振方面的应用进行了研究。介绍了GCSC的结构及基本控制原理,分析了GCSC稳态运行特性。对基于GCSC的各种不对称串补结构抑制次同步谐振的能力做了分析,采用复转距系数法求取电气阻尼来表示不对称串补结构缓解次同步谐振的效果。针对单相GCSC设计了次同步谐振阻尼控制器,并通过基于改进的IEEE次同步谐振第1标准测试系统的仿真,验证了所设计的GCSC不对称串补结构控制器不仅能够有效地抑制次同步谐振,且减少了投入的GCSC容量和工程费用。

关键词(KeyWords)： 次同步谐振;门级控制串联电容器;不对称串补结构;电气阻尼;控制器设计
