摘要
Abstract
A kind of improved control strategy based on power characteristic of wind turbine in different operating regions is presented. On the basis of comprehensively considering rotate speed control and power control,this method introduces pow-er feed forward controller in the variable pitch controller thus make output power respond to change of wind speed in ad-vance. In the torque controller,it adds torque compensation control which can make torque response more rapid when ro-tate speed is faster than rated rotate speed. In addition,a weighted average algorithm is introduced before determining set value of the torque so as to reduce mutation of the given torque with change of wind speed. MATLAB software is used to verify basic control strategy and improved control strategy respectively. Results indicate when the wind generating set is in transition zone,there is large disturbance in output value of power under traditional control strategy which means unsatisfac-tory control effect,while the improved control strategy would effectively restrain disturbance of gust to the torque which can make output power more smooth and reduce impact on the power grid.关键词
