摘要
该文对加入了统一潮流控制器(UPFC)的单机无穷大系统进行理论分析,引入Lyapunov直接法阐明通过UPFC来抑制低频振荡的机理,采用基于修正因子的模糊控制策略,设计相应的控制器,最后对单机系统进行了仿真,结果表明UPFC能有效地抑制系统的低频振荡,提高系统的稳定性。
This paper theoretically analyzes the single-unit infinite system which includes unified power flow controller (UPFC) , expounds how to inhibit low frequency oscillations by introducing Lyapunov method. The fuzzy control strategy based on the revision factor is adopted. The corresponding controller is designed. The results of the simulation on the singleunit systems show that UPFC can inhibit low frequency oscillations and improve system stability.
