Parametric analysis of resistance type vertical axis wind turbines

The performance of wind turbines is usually evaluated by proprietary parameters, but these parameters are used to analyze the dynamic performances of the blades qualitatively. Thus,it cannot exactly express the actual working performances of wind turbines. In this paper, a comparative analysis on physical meanings is made between resistance type vertical axis wind turbines and horizontal axis wind turbines. And the actual meanings of the parameters to be expressed was also discussed. The result shows that analysis theory of blades in different type of wind turbines are different. And then a design method was put forward to calculate and analyze the resistance type vertical axis wind turbines. It is concluded that wind turbines with different structures and blades have its own analysis theory and method.
