| Abstract: | In order to achieve efficient transmission of 2 MW wind turbines,the output characteristic curve of the adjustable vane torque converter is measured by the experimental method. The relationship between the three coefficients of turbine torque and turbine speed under different opening degrees is calculated. The mathematical model of planetary gear train for wind power generation hydraulic speed governing system is deduced. The control system of fuzzy self-tuning PID controller is designed. Dynamic simulation and experimental comparison of wind turbines are carried out. The results show that: the power values of numerical calculation are all larger than the experimental results. When the wind speed is less than 5 m/s,the output power is smaller and the absolute error is smaller. When the wind speed is greater than 5 m/s,the maximum error is 7%. |
