摘要
提出了一种新型的双转子永磁同步风力发电机,有两个螺旋桨,一前一后,设计集风套桶,可以二次利用风能,降低建压风速,提高风能利用率。在分析了双转子永磁同步风力发电机的工作原理、数学模型和特性的基础上,提出了一种适合管道式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,提高了系统风能利用率,具有一定的理论意义。
To build voltage under low wind speed,improve energy utilization and reduce cost,a novel dual-rotor permanent magnet synchronous wind power generator has been proposed which can utilize wind energy twice because it has two propellers one after the other and a wind sleeve.Based on the analysis of principle,mathematical model and characteristic of dual-rotor permanent magnet synchronous wind power generator,a maximum power tracking control strategy has proposed.Simulation results showed the correctness of control strategy,which has improved energy utilization and has certain theoretical significance.
