摘要
研究比较了最大风能捕获的3种算法:直接转速控制法、最佳功率—转速曲线跟踪法、爬山搜索法,从稳定性、可控性方面进行研究比较分析,并用所搭建的系统模型进行详细的仿真研究,仿真结果验证了基于最佳功率—转速曲线跟踪法的变速恒频双馈风力发电系统能够快速地进行最大功率点跟踪(MPPT),从而最大效率地利用风能。
Three maximal wind energy capture methods for the variable speed constant frequency doubly-fed wind power generation system, i.e. the wind turbine speed control method, the optimal power-rotor speed curve tracking method, and the climbing mountain searching method, are studied and compared in the aspects of stability and controllability. Simulations on the constructed system model show that the variable speed constant frequency doubly-fed wind power generation system based on the optimal power-rotor speed curve method can track the maximal power point and use wind power effectively.
