摘要
对开关磁阻风力发电机的运行原理和风轮机的功率输出特性进行了介绍,提出了一种不依赖风轮机运行参数即可实现最大风能自动跟踪的变步长控制方法。使用Matlab/Simulink构建了整个系统的模型,进行了仿真,使用直流电动机模拟风力机对提出的最大风能跟踪控制方法进行了测试,系统仿真和试验结果证明该方法是可行的。
This paper presents a variable step maximum power point tracking （MPPT） algorithm for switched reluctance generator （SRG） based on wind generation system （WGS）. The fundamental principle of the MPPT algorithm is based on monitoring the SRG＇s output power and speed to adjust the excitation phase current of SRG. The advantages of the proposed algorithm are that no knowledge of the wind turbine characteristics or measurement of the wind speed is required. The MPPT algorithm is simulated using Matlab/Simulink software, an experimental test system is developed in lab; the results of simulation and experimental test are used to prove its feasibility.
