Abstract :
To solve the connection to the grid and power control problems of doubly-fed variable speed constant frequency (VSCF) wind turbine control system , the method of rotor magnetic flux direct torque control (DTC) was used to regulate rotor side AC exciting ,and get the aim of controlling stator side output. The control principle was described, the trial control scheme was established, and the performance was verified by a 30 KW wind turbine trial platform .The trial results of control strategy were obtained on the process of synchronization and fore-and-aft getting connected to the grid. By testing and analyzing, the validity of the control method is confirmed ,which can be popularized to other similar generator system.
