摘要

本文提出了一种简单的变速和变负荷条件下异步发电机单机风能转换系统最大功率抽提控制策略。这是通过根据IG终端负载的变化改变逆变器频率和调制指数来实现的。所提出的方法消除了对速度编码器的需要,因此它是一种有吸引力的无传感器控制方法。在MATLAB/SIMULINK中对所开发的模型进行了仿真。仿真结果验证了所提出的控制策略。控制算法在TMS320F243 DSP上实现。实验结果与仿真结果接近。

Novel maximum power point tracker for stand-alone self-excited induction generator
In this paper, a simple control strategy for maximum power extraction from stand-alone wind energy conversion system using induction generator under variable speed and load conditions is proposed. This is achieved by varying the inverter frequency and modulation index depending upon the changes in load at the IG terminal. The proposed method eliminates the need of a speed encoder, and hence itpsilas an attractive sensor-less control method. The developed model is simulated in MATLAB/SIMULINK. The simulation results are presented to validate the developed control strategy. The control algorithm is implemented on TMS320F243 DSP. Experimental results closely resemble the simulated results.
