摘    要:为改善模糊电力系统稳定器(FPSS)的动态性能,提出了基于滑模控制的FPSS的控制策略.在该控制策略中,电力系统稳定器(PSS)由主控制器、自组织控制器和滑模控制器三部分构成,其中,主控制器用于产生PSS的基本输出信号;自组织控制器可根据滑模控制器输出的优化条件对主控制器进行优化设计.还提出了采用滑模控制器代替传统的线性控制器来输出优化条件.理论分析和仿真结果表明,文中FPSS的动态性能优于常规的模糊稳定器.

关 键 词:滑模控制  电力系统稳定器  自组织控制器  电力系统

Abstract:To improve the dynamic performance of fuzzy power system stabilizer (FPSS), a control strategy for FPSS based on slide mode control is put forward. In this scheme, the proposed PSS consists of main controller, self-organizing controller and slide mode controller. The basic output signal of PSS is produced by main controller and the self-organizing controller is used to optimize main controller according to the updating conditions output by slide mode controller. It is suggested that the traditional linear controller can be replaced by slide mode controller to output the optimizing condition which can enhance the robust of PSS to restrain change of parameters, non-linearity and noise. The results of theoretical analysis and simulation show that the dynamic performance of the proposed FPSS is better than traditional fuzzy stabilizer.
Keywords:Slide mode control  Power system stabilizer  Self-organizing controller  Power system
