【摘要】 针对电力系统非线性特性,采用反馈线性方法,以改善电力系统暂态稳定性为目标,应用线性二次型最优控制理论探讨了TCSC和发电机励磁系统的分散协调控制规律。最后应用Matlab软件对单机无穷大系统进行仿真试验,结果表明:所设计的控制规律能有效提高系统暂态稳定性。由于控制信号实现了本地化,本文所设计控制器具有一定工程实用性。更多还原

【Abstract】 Aimed at the nonlinear characteristic of power system, a decentralized linear optimal coordinated control law about TCSC and excitation system of Turbo-generator is finally founded based on the feedback linearization method and linear quadratic optimal control theory. The simulation shows that the transient stability of the power system is obviously improved which performed on a single-machine infinite-bus system. The control law has engineering practicality since the variables can be measured locally.更多还原
