Measurement and analysis of aerodynamic characteristics of new off-grid wind turbine

Under the low speed wind tunnel,experiments were carried out to study the aerodynamic characteristics for two horizontal axis wind turbine of different airfoil,as the result,the authors got the power curve of wind turbine.Then,WAsP software was used to evaluate local wind energy resources,orderly to obtain the wind atlas through analysis and calculation.Finally,the annual energy production per unit area was calculated for two different airfoil wind turbine in different area.The results showed that in the actual wind farm the generating capacity per unit area of the new airfoil wind turbine increased 28.4% compared with the conventional wind turbine.
