| Abstract: | This paper analyzes the operation principles of wind turbines and direct current(DC) motors,and develops a mathematic model for the wind turbine.A new method is proposed to control the wind turbine imitation system below rating wind speed,which adopts a double close-loops control method containing an outside power loop and an inside torque loop to control the DC motor.In order to achieve maximum power,in the wind generator system,the PMSG has to be worked in an optimal speed by changing the given value of s... |
