摘要(Abstract)：

基于交直流系统潮流方程雅可比矩阵的特征结构分析法,提出了一种利用可控串联补偿器(thyristor controlled series compensator,TCSC)提高交直流系统静态电压稳定性的方法。该方法研究了交直流系统潮流方程雅可比矩阵的最小模特征值,以节点电压对无功功率变化的灵敏度为指标,结合参与因子,判断全电网中最有可能发生电压不稳定的节点或者区域,从而为系统无功功率补偿装置的配置提供决策依据。对美国西部5机14节点系统进行了仿真计算,验证了TCSC在交直流系统中提高静态电压稳定性的可行性、有效性和正确性。

关键词(KeyWords)： 交直流系统;特征结构分析法;可控串联补偿器(TCSC);静态电压稳定性;最小模特征值
