摘要

统一潮流控制器（UPFC）的交叉解耦控制具有潮流调节迅速、稳定性好的优点，但是其功率环反馈系数按固定参数设定，因而鲁棒性较差。文中以阻抗跟踪法改善交叉解耦控制的鲁棒性。该方法将功率环的反馈系数由固定参数改变为线路阻抗的跟踪值，在保证交叉解耦控制原有良好潮流调节性能的同时能够对不同的线路阻抗实现潮流调节。同时，阻抗跟踪法没有引入新的采样信号，易于实现。仿真结果证明了这种控制方法具有良好的鲁棒性。

Abstract

The decoupling control scheme can modulate power flow rapidly and stably in UPFC

but the feedback value is set at a constant point in the power loop. This control scheme has unsatisfactory robustness performances. This paper improves the decoupling control scheme with the impedance tracking. In this method

the feedback value would change from constant value to the tracking value of impedance in the line. So the decoupling control scheme can modulate the power flow of different impedance parameter

and it can modulate the power flow rapidly and stably as usual. The impedance tracking does not increase any sampling signals

and it is easily achieved. Simulation results show that the decoupling control scheme has good robustness.
