Fuzzy power factor controlling and simulation of brushless doubly-fed wind generator

以变速恒频风力发电为背景,根据无刷双馈电机原理和模糊控制理论设计了模糊控制器,应用此模糊控制器对无刷双馈电机发电运行状态的功率因数进行控制,并在Simulink环境下进行了仿真。仿真结果表明,模糊功率因数控制器很好地追踪了功率因数的变化,并且保证了功率绕组电流频率不变,实现了变速恒频发电。

In the background of VSCF wind power generation,according to BDFM＇s running principle and the theory fuzzy logic controller,the fuzzy logic controller for BDFM＇s power factor controlling is established.Under the the Simulink environment,power factor of BDFM＇s generation operation status applying the proposed fuzzy controller is controlled and the simulation is finished.The simulation results show that the fuzzy power factor controller has a good track of power factor changes,a nd ensure the frequency of power winding current unchanged to achieve a variable-speed constant frequency power generation.
