中文摘要: 针对包含时滞不确定性和参数不确定及负荷扰动的单域电力系统,提出了滑模负荷频率控制策略.通过Matlab/Simulink平台,搭建仿真算例,检验所提出的控制器在时滞电力系统不同工作点运行且考虑发电机变化约束(GRC)的情况下的鲁棒性和控制性能.仿真结果显示,与不含滑模控制的时滞电力系统相比,采用滑模控制器使时滞系统的响应速度快,并且具有更好的鲁棒性.

中文关键词: 负荷频率控制时滞系统滑模控制电力系统

Abstract:The strategy of a single area power system load frequency sliding mode control is proposed for the single area power system with parameter uncertainties and load disturbance.Through the platform of Matlab/Simulink, its robustness and control performances of the proposed controller are examined when the power system is at different operating points and under GRC. The simulation results show that time delay system with sliding mode controller has a quicker response and better robustness than the one without sliding mode controller.
