Abstract：In order to study the maximum wind power capture of wind turbine and the aerodynamic load of blades below the rated power and make the wind turbine run efficiently and stably in whole life cycle,a cooperative control method for both power and load was proposed.Through adopting the pre-pitch strategy in the transition zone,the aerodynamic load of blades and the power of wind turbine were controlled. Through adopting the proposed power and load cooperative strategy,a simulation model for the wind turbine was established with Matlab software,and the data for the power of wind turbine and the aerodynamic load of blades were calculated.The results show that the cooperative control strategy can effectively reduce the aerodynamic load of blades under the condition of keeping the power basically unchanged in the districts below the rated power.Therefore,the feasibility of the proposed cooperative control strategy is proved.
