从应用角度,尝试将模糊控制与常规PI控制结合来控制STATCOM向电网注入或吸收无功功率,从而稳定接点电压,这种方法既充分利用PI控制精度高,又兼有模糊控制的灵活,适应性强,尤其在电网参数变化的动态过程中,可明显提高STATCOM的动、稳特性。
From the application point of view, try to control the STATCOM injection or absorption of reactive power STATCOM combined with conventional PI control to stabilize the contact voltage, this method not only make full use of PI control with high precision, but also have the flexibility of fuzzy control, Especially in the dynamic process of grid parameter changes, the dynamic and steady characteristics of STATCOM can be obviously improved.
