| 中文摘要 | 广域阻尼控制是抑制电力系统区间低频振荡极具潜力的手段,降阶辨识方法可用于获取广域阻尼控制器设计所需要的模型。电力系统的维数成千上万,基于模式可控可观性分析提出了电力系统面向阻尼控制器设计的可降阶原理、降阶误差分析方法以及基于降阶原理估计和BIC准则的模型定阶方法,并研究了降阶辨识实验的激励信号和预滤波器设计。四机系统的仿真算例表明了所提出的面向广域阻尼控制的电力系统降阶辨识原理与方法的有效性。; Wide area damping control has a great potential on the damping of inter-area low frequency oscillations. Reduced order system identification provides a feasible solution to get the system model for damping controller design. In this paper,the principle of control oriented power system order reduction is studied based on mode controllability and observability analysis. Then model reduction error is analyzed and a model order selection method is proposed according to reduction error analysis and BIC criterion. Then an input and pre-filter design method is proposed for damping control oriented identification experiments. The principle and methods proposed in this paper are verified in a four machine two area system. |
