수직축 풍력터빈의 기동특성에 관한 연구

The wind power generation system is divided by two types, horizontal axis wind turbine(HAWT) and vertical axis wind turbine(VAWT). The VAWT can be used at low wind speed, and it does not influenced by the direction of the wind. But the efficiency of the VAWT is lower than the HAWT. So, it is necessary to solve this problem. And many researchers make an effort to solve the problem. The objective of this study is to investigate the aerodynamic characteristics of the vertical axis wind turbine blade, and we also compared the torque values of various type of the VAWT blades. In conclusion, the efficiency of the blade type 2 is higher than the blade type 1.
