摘　　要：采用一种新的带自调整因子的模糊变结构汽门控制规律，对电力系统的暂态过程进行控制。这种控制方式既保留了传统的滑动模态控制的优点，又解决了高频抖动的问题，同时也提高了控制的鲁棒性。经过对单机无穷大系统及多机系统的计算机仿真计算表明，采用这种方法，能更好地改善电力系统的暂态稳定性。A new fuzzy varlable structure control method for turbine valve with self-adjusting factor is applied to the controlfor transient process of power system. This control method retains the positive properties of conventional sliding modecontrol. and solves the problem of high frequency shiver. as well as increases the robustness of the controller. The computersimulation results of a slngle-machine infinite-bus system and a multi-machine system show that this method can improve thetransient stability of power system.
