摘　　要：针对双馈风力发电机有功和无功控制的自适应能力和控制精度的问题,本文设计了一套基于变论域模糊控制的高性能双馈风力发电机控制系统。由于风速的改变使得发电机转速及各参数都会改变,因此在Matlab环境下将电机参数在运行过程中随不同工况改变而改变这一因素考虑进去,进行了不同工况下的系统仿真试验,试验验证了基于变论域模糊控制策略是可行的,实现了有功功率和无功功率的解耦控制,并具有自适应能力强和控制精度高的良好动态特性。For the adaptive capacity and precision of a double-fed wind generator active and reactive power control,according to the stator field oriented vector control theory,through the coordinate transformation,decoupling control of the mathematical model of the active power and reactive power is established,a high-performance double-fed induction wind generator control system is designed based on variable universe fuzzy control.Experimental results in Matlab show that control strategy method based on variable universe fuzzy control is feasible to achieve the active and reactive power decoupling control,and it has some good dynamic characteristics:strong adaptability and high control accuracy.
