摘要
提出了一种基于分区变步长爬山法的双馈异步风机最大功率点跟踪控制策略,在吸取传统爬山法优点的基础上,给出了一种新的爬山法扰动步长分界方法和整定方案。该策略在风速稳定时能有效地抑制转速的波动,在风速发生变化时能较快地跟踪最大功率点,能有效改善双馈风力发电系统的稳态性能和动态性能。并通过仿真和实验验证了理论分析结果。
Presented a doubly-fed asynchronous wind turbine MPPT control strategy based on partition variablestep size hill-climbing method,this strategy had absorbed the advantages of the traditional climbing method,gave anew step dividing method and tuning scheme. The partition variable step size hill-climbing MPPT control strategycould effectively suppress the fluctuation of the rotation speed when the wind speed was stable,and could track themaximum power point quickly when the wind speed was changed,the steady performance and dynamic performanceof the doubly-fed wind power generation system could be effectively improved. The theoretical analysis results areverified by simulation and experiment.
