Abstract: Aiming at the defects of modeling and control methods in pitch loading system of wind turbine, the compensating torque of blade simulation system was analyzed, and the control of the loading system was improved. The combination of torque closeloop control and optimization of torque compensation was introduced. The operation of 2.5MW wind turbine was simulated based on Bladed, meanwhile, the model was used in simulating the working condition at site, helping to control the platform and having loading test.The experimental data of platform and the simulation results were compared. They were coincided well. The results indicate that the combination of torque closeloop control with torque compensation optimization can truly reflect the conditions of blade in the wind field. It makes the control of pitch loading system achieve the optimal.

Key words: pitch loading system; closeloop control; torque compensation; simulation
