本文探讨了大系统分散输出反馈控制的设计方法,并将其应用于多机电力系统的稳定控制问题。文中提出了分散信息限制的等式表示形式,并给出了电力系统的分散输出反馈控制方案。最后针对某两机一负荷无穷大母线典型系统进行了设计和研究。研究结果表明:在非线性系统中,适当的分散输出反馈控制不仅比全局最优状态反馈控制简便,且可能取得更好的效果;文中提出的分散输出反馈控制方案具有效果好,易于实现,适应性较佳等优点,是一种很有应用前途的电力系统稳定控制方案。
This paper discusses the design method of decentralized output feedback control for large-scale systems and applies it to the stability control of multi-machine power systems. In this paper, we put forward the equation representation of distributed information restriction and give the decentralized output feedback control scheme of power system. Finally, the design and research of a typical system of a two-machine-one bus with infinite load is carried out. The results show that decentralized decentralized output feedback control is not only simpler than the global optimal state feedback control in nonlinear systems, but also may achieve better results. The decentralized output feedback control scheme proposed in this paper is effective, easy to implement and adaptive Better sex, etc., is a promising application of the power system stability control program.
