摘要
为了加宽工作风速范围,在低风速时也能建压,提高风能利用率,介绍了一种新型的双转子永磁同步风力发电机,在分析了双转子永磁同步风力发电机的工作原理、数学模型的基础上,提出了一种适合低风速的双转子永磁同步风力发电系统的最大风能跟踪控制策略。仿真结果证明了控制策略的正确性,并且控制简单,运行可靠,具有一定的理论意义。
In order to widen the range of workable velocity, to make the generator able to establish usable voltage at low wind velocity and to improve the energy utilization, a novel dual-rotor permanent magnet synchronous wind-driven generator was proposed. Based on the analysis of operating principle and mathematical model of the generator, a maximum power tracking control strategy applicable for low wind velocity situation was discussed. Simulation results show the correctness of the control strategy. Moreover, this control method is simple, reliable and has certain theoretical significance.
