Air Resistance Test of 1.5kW H-type Vertical Axis Wind Turbine

Wind power gradually becomes new important energy source.With the development of the wind power,it is well known that the vertical axis wind turbine has many advantages:for examples,it does not need to adjust the turbine with the direction of wind changing;so there need no the yaw device and pitch controlled device.As compared with the wind turbine,H-type vertical axis wind turbine has the advantages of more wind swept area,light weight,small inertia and simple structure.We test the torque of 1.5kW H-type vertical axis wind turbines with different solidity and different structure under the condition of no wind by motor drive.We understand the effect of the different structure on vertical axis wind turbine by comparison with the test data.This paper gives a reference to the optimum design of the MW vertical axis wind turbine.
