Abstract

Savonius wind turbine design use type two blades with a diameter of 15.5 cm, a height of 10.9 cm and turbine weight of 51.3 g. The Darrieus wind turbine design uses type three blades with dimensions 21.8 cm x 8.7 cm x 2.3 cm. The weight of each blade is 51.3 g with the angle between the blades being 120⁰. The voltage of 2.5 V produced a minimum turbine rotation speed of 284.2 rpm and a maximum of 296.0 rpm. When the voltage was increased to 5.0 V, the minimum speed is 342.8 rpm and a maximum speed of 366.4 rpm. When given a voltage of 7.5 V, a minimum speed of 461.7 rpm and a maximum of 481.3 rpm were produced.

Highlights

  • The most commonly used wind turbine is the Horizontal Axis Wind Turbine (HAWT) in which the axis of rotation is parallel to the ground

  • There is another type of wind turbine, the Vertical Axis Wind Turbine (VAWT) which is the focus of this study [1, 2]

  • VAWT has two types of turbine configurations, i.e. the drag type where the wind turbine moves due to drag force against the wind captured by the blade and the type of lift where the wind turbine moves due to lift force to the wind [5]

Summary

Introduction

The most commonly used wind turbine is the Horizontal Axis Wind Turbine (HAWT) in which the axis of rotation is parallel to the ground. There is another type of wind turbine, the Vertical Axis Wind Turbine (VAWT) which is the focus of this study [1, 2]. Wind energy is an energy that can be used to drive turbines. A wind turbine is a system that functions to convert wind kinetic energy into mechanical energy on the turbine shaft. There are two types of wind turbines, namely Horizontal Axis Wind Turbine (HAWT) and Vertical Axis Wind Turbine (VAWT)
