包含静止无功发生器的电力系统鲁棒H∞控制

摘要

A class of hybrid uncertain system is put forward in respect to nonlinearity and uncertainty of power systems with SVG ( static VAR generator). The design method of robust H∞ controller for the system is given and applied to multi-machine power system with SVG. The controller for SVG and excitation of generators is designed.The simulation results verify effectiveness of the controller.%针对包含静止无功发生器的电力系统存在的非线性和不确定性,提出了一类混合不确定系统的一般描述及其鲁棒H<,∞>控制器的设计方法.将这一方法应用于包含静止无功发生器的多机系统中,用以设计系统的静止无功发生器和发电机励磁控制器.对所给系统给出了仿真实验结果,论证了控制器的有效性.
