电力系统新型非线性励磁控制器

A New Nonlinear Excitation controller for Power Systems

提出了一种非线性控制器的设计方法，所得到的新型励磁控制器是非线性的，由完全线性化（ＣＬ）补偿器和鲁棒最优输出反馈控制器组成，经过单机无穷大母线系统及多机等值模型的数字仿真和单机无穷大母线系统的动模实验，证实新型控制器在提高输电系统稳定性方面具有一系列突出的优越性。

A design method of nonlinear controller is proposed in this paper.The new excitation controller is nonlinear and is composed of the complete linearizing(CL)compensator and the robust optimal output feedback controller. Digital simulation of synchronous machine against an infinite bus system and an 8-generator equivalent system in a certain province in China, and physical experiment of a synchronous machine against an infinite bus system prove that this controller has a number of expellent performance properties in improving power system stability.
