摘　　要：有效的发电机励磁控制是提高电力系统动态性能的主要手段之一。提出了一种基于电压和角速度信号联合反馈的模糊PID控制方案,利用模糊推理整定PID参数,以增强对动态环境的适应性。针对单机无穷大系统,设计模糊推理规则,获得自适应控制参数。仿真结果表明,本控制方法对动态扰动具有较好的鲁棒性。Effective excitation control of generator is one of the main techniques to improve the dynamic performance of power system.In this paper,a fuzzy PID control scheme is proposed based on the feedback signals of voltage and angel velocity.In order to increase the adaptability for the dynamic conditions,PID parameters are achieved by fuzzy inferring.The fuzzy inferring rules are designed,and the adaptive control parameters are gained for the single-machine infinite system.Simulation results show that the proposed control method in this paper has better robustness against the dynamic disturbances.
