Abstract: The utilisation of wind energy draws on the rediscovery of a long tradition of wind power technology to vertical-axis wind turbine generation system. A three-hastate wind wheel for vertical-axis wind turbine, which can be driven by the intra-cavity wind energy secondarily, is proposed according to the wind energy performance and the hydrodynamics theory in this research project. Structure and parameters of the wind wheel are designed. A simplified test model is made similar to the real dimension of the wind wheel to investigate its performance. A simple opening straight-flow wind tunnel is also used which is composed of wind tunnel, wind wheel test bed and testing instruments. Characteristics of the model are testified in wind tunnel tests while it is under or without loads, which include start-up wind speed, torque, correlations among wind speed, power, tip speed ratio and rotor power coefficient, etc. The experimental results show that this type of wind wheel has many advantages such as simple structure, high utilisation efficiency of wind energy, low start-up wind speed, high equipment reliability and good maintainability.

Keywords: three-hastate wind wheels; vertical-axis wind turbines; utilisation efficiency; wind energy; wind tunnel testing; wind power; hydrodynamics theory.
