简述变速恒频双馈风电机组并网原理

Description of VSCF Doubly Fed Wind Turbines and Net Principle

变速恒频双馈风电机组是目前国内外风电机组的主流机型，其发电设备为双馈感应发电机，由变频器给转子提供励磁，使发电机定子上感应出与电网电压频率、幅值、相位一致的电能，本文对变速恒频双馈风电机组的并网原理进行了简述。

VSCF doubly fed wind turbine is the mainstream model of wind turbine at home and abroad. Its power generation equipment is the doubly-fed induction generator which the excitation driven from the rotor could make the stator of generator induce an equal electrical energy from the voltage, frequency, amplitude and phase of the grid. This paper will provide you a briefly outline of principle and mechanism on how the VSCF doubly fed wind turbines are paralleled in the grid.
