【摘要】 由于双馈式变速恒频风力发电系统其转子转速具有可调性,所以可通过调节发电机转子转速以获得最大风能。首先介绍风轮机的功率特性,列举两种现有的最大风能跟踪控制算法,其中着重分析常用的变步长爬山法,随后以双馈式发电机为例,提出把黄金分割法应用于最大风能追踪的设想,最后采用MATLAB软件对3种算法进行仿真对比。仿真结果表明,黄金分割法具有可行性,在风能追踪精度与速度上具有优越性。更多还原

【Abstract】 Because doubly-fed variable speed constant frequency wind power generating system is adjustable,the maximum wind power can be got by adjusting the rotor speed of the induction generator.The power characteristic of wind turbine was first introduced in this paper,and two types of existing maximum wind power track algorithms are advanced,focusing on analysis of the variable step mountain climb algorithm.Then taking a doubly-fed generator as example,the paper applied gold segmentation algorithm to tracking maximum wind energy.Finally,MATLAB software was used to simulate the three algorithm,and the results proved that the gold segmentation algorithm has feasibility,higher accuracy and less tracking time.更多还原
