摘要(Abstract)：

2015年底在江苏南京正式投运的中国首台统一潮流控制器(unified power flow controller,UPFC)采用矢量控制策略的模块化多电平换流器。已发表文献中多为关于传统相角控制型UPFC装置交互影响的分析研究,而对矢量控制UPFC与HVDC间的交互影响研究还不够深入。为深入了解UPFC接入对特高压交直流混联电网的影响,文章新建了矢量控制UPFC的非线性数学模型,基于分块化思想构造了包含HVDC系统与矢量控制UPFC的多机全系统开环线性化模型,应用相对增益矩阵(relative gain array,RGA)方法定量分析UPFC控制器、UPFC与HVDC系统间的交互影响强弱,并通过阶跃仿真验证RGA结论的正确性。此外,还通过对发电机功角的非线性仿真以及曲线的Prony分析结果,验证UPFC接入对江苏电网系统低频振荡阻尼特性的影响。

关键词(KeyWords)： 统一潮流控制器;矢量控制策略;相对增益矩阵;交互影响;阻尼特性
