摘　　要：构建了二端统一潮流控制器(T-UPFC)的动态模型,该模型充分考虑了T-UPFC内部的调节过程,计及了T-UPFC逆变器的调制过程以及直流电容的充放电过程。将模糊神经网络(FNN)应用于T-UPFC的控制设计。系统仿真表明了在频率波动较大情况下,所设计的T-UPFC性能优越,能有效、快速地抑制系统后续摆的振荡,从而提高了系统的动态稳定性。The dynamic model of the T-UPFC was constructed . This model considers the process of T-UPFC＇s internal modulation and converters and the process of charge and discharge for DC capacitance. Fuzzy neural network controller （FNNC） was applied to the T-UPFC based on the dynamic model. The simulation results verify the efficiency of the designed T-UPFC. It can damp the subsequent swing quickly under serious power oscillation circumstance to enhance the system dynamic stability apparently.
