本文根据有控制结构约束的分散控制理论研究了电力系统分散最优励磁控制,并采用系统的性能指标确定反馈信号以及控制器安装顺序。为了验证所提控制方案对于抑制系统振荡及提高系统稳定性的效益,对一个三机系统做了动态物理模型实验及数字仿真。
In this paper, decentralized optimal excitation control of power system is studied based on the decentralized control theory with control structure constraints. The feedback signal and the sequence of controller installation are determined by the system performance index. In order to verify the effectiveness of the proposed control scheme for suppressing system oscillations and improving system stability, a dynamic physical model experiment and numerical simulation of a three-machine system are carried out.
