Abstract

This paper reports existing studies on the influence of the number of blades on vertical axis wind turbine (VAWT) performance. Wind turbine blade is an important element in the conversion of wind energy to electrical energy, because of their ability to convert wind kinetic energy, even at low wind speeds. Therefore, the choice of airfoil-shaped wind turbine blades is very suitable for application in areas with low wind speeds. The VAWT blade installed resembles a pumpkin when it spins, so is called a pumpkin wind turbine. The blades were installed on VAWT with various 2, 3, 4, and 5 blades, while the performance of the wind turbine was determined with various wind speeds, respectively. The successful manufacture of blades can be an advantageous solution for vertical wind turbines. The turbine with three blades has the largest tip speed ratio (TSR) of 4.08. The test results of this pumpkin wind turbine show the maximum efficiency power expressed in Cp of 0.49 with the number of three blades. For application, a vertical pumpkin wind turbine with a stand- alone has been installed for lighting in Mount Ireng in Pengkok Village Patuk Gunung Kidul Special Region of Yogyakarta.
