发电机调速系统的模糊逻辑控制器

Fuzzy Logic Controller for Generator Governor

本文基于发电机速度／加速度相平面上的标准模糊隶属函数提出了电力系统发电机调速系统的模糊逻辑控制器．这种模糊逻辑控制器的输入信号可由模糊隶属函数和增益所确定，其中模糊控制器的增益可以表示为系统短路功率的函数，由此，整个控制器不需任何参数调整．通过对简单电力系统的仿真研究表明，调速系统的模糊逻辑控制器对于系统参数和运行方式的变化以及不同的故障程度等都具有很强的鲁棒性和很高的智能水平．

Fuzzy logic controller of generator governor is presented in this paper based on fuzzy membership function on the phase plane of speed and acceleration. Input signal of the controller is determinedby membership function and its gain which can be described as the function of generator electrical powerduring disturbance. Therefore all the parameters of the controller need not be modified on-line. Simulationon the simple power system show that the controller has strong robustness and high intelligence for thevariation of the parameters,the changes of operation conditions and all kinds of disturbances of power system.
