Experimental Study of Aerodynamic Characteristics for Horizontal Axis Wind Turbine and Performance Evaluation

This study using two different airfoil of horizontal axis wind turbine in order to evaluate the performance good or bad with unit area of power generation. First, under the low speed wind tunnel, two different airfoil of horizontal axis wind turbine on experimental study of the aerodynamic characteristics, got the power curve of wind turbine; Then, based on the wind resource date in 2008 from four areas in Inner Mongolia, which was provided by the China meteorological date sharing service system, the local wind resources were estimated by using Wasp software and the wind atlas could be obtained by analysis and calculation. On the digital map of a given area, the simulated wind turbine station was established. Finally, the annual energy production per unit area of two different airfoil of horizontal axis wind turbine in order to evaluate the performance. The results showed that: in the actual wind farm wind turbine of the new airfoil than wind turbine of the NACA4412 airfoil on wind turbine generating capacity per unit area evenly increased by 28.4%.
