Research on Aerodynamic Torque Model Optimization of Horizontal Axis Wind Turbine
To obtain accurate control instructions for grid-connected power generation control of wind turbines,the output characteristics of wind turbines are explored based on control requirements,and their aerodynamic torque is accurately modeled.Combined with the measured data and ANSYS simulation,the blade deformation of AH-30 kW variable pitch wind turbine is studied under the influence of typical materials and the output characteristics.The results show that the elastic deformation of small and medium-sized wind turbines due to different blade materials is small deformation,and the influence on the torque model of wind turbines and unit control can be ignored.The output torque of wind turbine fluctuates and quivers greatly under the influence of wind.It is necessary to comprehensively consider the impact of multi-source disturbances on the control performance of the unit.By combining the measured data with Fluent simulation,the output error between the corrected mathematical model of wind turbine aerodynamic torque and the Fluent simulation is 5.6％.It can reflect the real output characteristics of wind turbines,and it lays a theoretical foundation for the grid-connected power generation control of wind turbines.
