Abstract: Abstract : -Most of wind turbines use induction generators that are very reliable with low costs [2], but when it is straightly connected to the grid, maximum power is not accessible [1] and only a few change of speed between maximum speed and synchronous speed is possible [1]. In this report, a doubly-fed induction generator with winding-rotor configuration, external rotor resistance and external rotor source that has a variable phase and amplitude is used. This doubly-fed induction generator has larger range of change of speed than induction generator and its application in wind systems is very common. Also in doubly-fed machine, both active and reactive power control is possible [3]. In this report, a doubly-fed induction machine with an improved wind turbine has been simulated, then with selecting suitable control parameters by open loop controlling, maximum turbine active power at an adapted speed is exerted to the grid and the results is presented.
Keywords: Key words: -Doubly-fed machine, Wind turbine, Gearbox ratio, Low speed shaft, High speed shaft.
