摘要
为了提高双馈型机组低风速段的风资源利用率,本文提出了一种最优的双馈风电变流器系统及控制方法。该系统根据风速大小对发电机定子电路连接进行Y/△切换提高低风速段发电量。通过仿真、试验以及风场验证了该变流器系统及控制的可行性、稳定性。
In order to improve the wind resources utilization rate of doubly fed induction generator(DFIG)under low wind speed conditions,an optimal doubly fed wind power converter system and its control method are proposed in this paper.According to the two wind speeds of high/low,Y/△switching for the generator stator circuit connection is carried out correspondingly to improve the power generation at low wind speed.The simulation,experiment bed and wind field tests of the system were completed.It is concluded that the converter system are of the feasibility and stability of its control.
