双馈电机变速恒频发电原理
通过对风力机转速的控制，可以实现最大功率点跟踪，尽量多地吸收风能；而调节无功功率可以控制向电网输出的功率因数，也可提高风电机组及电网系统的动、静态运行稳定性-VSCF doubly-fed electrical power through the principle of wind turbine speed control, maximum power point tracking can be achieved as much as possible to absorb wind energy and regulation can control the reactive power output to the grid power factor, but also can improve the wind turbine and power system dynamic and static operation stability
