摘要
将多变量的逆系统方法用于大型汽轮发电机组的综合控制 ,综合考虑了励磁控制和汽门开度控制。基于逆系统思想选取功角δ和发电机输出电压νt 作为电力系统的输出 ,获得了电力系统的α阶积分逆系统 ,由此设计了非线性解耦最优控制律 ,以同时提高系统的综合性能。计算机仿真结果表明 ,所设计的控制律可有效地提高发电机的稳定性和电压精度。
Integrated control of power system may improve the integrated performance of the system. Multi-variable inverse system method is applied to large turbo-generator set integrated control of excitation and steam gate opening in this paper. Based on the system inverse idea power angle δ and terminal voltage ν t are chosen to be outputs, then α -order integral inverse system and nonlinear decoupling optimal control law is designed. The computer simulation shows that the proposed control law may improve power system stability and voltage regulation accuracy.
