摘要
介绍了变速恒频交流励磁双馈电机的风力发电系统。在检测不同风速下,给出最佳电机转速,再根据定子磁链定向方法对电机的有功功率和无功功率的解耦控制,实现最大风能捕获。给出了系统仿真模型和仿真结果,验证了系统控制策略的可行性和正确性。
The variable speed constant frequency AC-excited wind turbine system based on doubly-fed induction generator（DFIG） was discussed. By testing different wind speed, rotor speed reference of machine was given and the stator-flux oriented control strategy was used to control active and reactive power of machine independently and realize maximal wind energy capture. The test model and the resuh of the system and the validity and feasibility of the control strategy were given.
