电力系统的运行方式和结构的时变特性越来越突出，传统广域阻尼控制器(conventional wide-area power system stabilizer，CWAPSS)由于参数固定，无法保证系统在不同运行状态下的控制效果。为此，文章采用无模型自适应控制(model free adaptive control，MFAC)算法实现了具有自适应功能的广域阻尼控制器的设计。首先讨论了 MFAC 算法的基本原理；然后通过分析比较WAPSS和MFAC算法参数之间的关系，给出了 MFAC 算法的参数设置方法；最后，通过四机两区系统的仿真验证了 MFAC 算法的有效性。仿真结果表明在系统结构发生变化时，无模型自适应广域阻尼控制器能够在线调整控制器参数，控制效果优于CWAPSS。

The time-varying characteristics of power grid operating modes and structure become more and more conspicuous, and due to fixed parameters of traditional wide-area power system stabilizer (WAPSS) the control effect of power grid under various operating conditions could not be ensured. Utilizing model-free adaptive control (MFAC) algorithm the authors implement the design of adaptive wide-area damping controller. Firstly, basic principle of MFAC is discussed; then the relationship between parameters of WAPSS and those of MFAC are analyzed and compared and the method of parameter setting of MFAC algorithm is given; finally, through simulation of a 4-machine 2-area system the effectiveness of MFAC algorithm is validated. Simulation results show that during the change of power system structure the online adjustment of parameters of the model-free adaptive wide-area damping controller can be implemented, and its control effect is better than WAPSS.
