| Abstract: | In order to research wind power generation in laboratory,a feasibility plan to imitate the performance characteristic of wind turbine by using DC motor is proposed,then the performance characteristic and the operation principle of optimum utilization of wind energy are analyzed.Based on this principle,the torque characteristics of wind turbine are imitated by controlling the torque of DC motor.The whole wind turbine imitation system includes hardware platform comprising industrial computer,signal acquisition board,power loading feedback controller and wind turbine imitation software.The imitation is done under two typical condition of variable machine velocity and natural wind,experimental results of control system show the correctness of this programme. |
