When pitches are controlled,the output power and blade aerodynamic loads of wind turbine will be all changed.The study considers the internal laws and linkages of power and the load with the change of the pitch angle.Firstly,the input and output peripheral interface circuits of wind turbine are designed and installed in the laboratory.Secondly,semi-physical simulation platform of wind turbine about pitch control is built.Finally two pitch control experiment projects are designed and developed to verify the correctness and effectiveness of the developed experimental platform.Through the simulation of wind speed and the semi physical simulation experiment,the following two experimental results are achieved：（1） the relationship between power and blade aerodynamic load varying with the pitch ang
