基于预测函数控制的电力系统励磁控制

The Excitation Control of Power System Based on Predict Function of Control

励磁控制系统是同步发电机中重要的组成部分,其性能好坏直接影响电力系统运行的可靠性和稳定性。预测函数控制(PFC)是在预测控制原理的基础上发展起来的一种控制方法,相对而言,PFC拥有算法简便、在线计算量小等特点,且跟踪速度快。将预测函数控制算法用于同步发电机励磁系统中,通过MATLAB仿真,并与PID控制器的仿真进行比较,可以看出预测函数控制有更好的控制效果。,

The excitation control system plays an important role in power system.It can be used to maintain generator terminal voltage and improve power system stability.The predictive functional control(PFC) is developed on the basis of the predictive control,the PFC has simple algorithm,less calculation online,and track a target fast.This PFC control algorithm was applied to synchronous generator excitation system.Results through MATLAB simulation confirm that,compared with PID control,the PFC control algorithm shows better controlling ability.
