摘要(Abstract)：

在装设了统一潮流控制器(unified power flow controller,UPFC)的弱阻尼连接多机系统中,综合利用全系统的线性化状态方程和传递函数的信息,设计了线性化的UPFC稳定控制器。为使该稳定控制器能在系统大范围内的运行点提供有效阻尼,文中在UPFC稳定控制器中加入一可调的超前(滞后)环节,利用Prony分析在线辨析系统低频振荡特性。利用在线辨析的结果对稳定控制器的可调环节进行微调,使之针对系统具体运行工况进行自适应校正,从而持续工作在最佳状态。最后利用电磁暂态仿真程序对一个装设有UPFC的两区域弱阻尼连接系统进行了仿真计算。仿真结果表明,文中设计的自适应校正UPFC稳定控制器能够明显提高该系统的阻尼水平。
