<p>A vertical axis wind turbine triple-stage savonius type has been created by using simple materials to generate electricity for the alternative wind power plant. The objective of this research is to design a simple wind turbine which can operate with low wind speed. The turbine was designed by making three savonius rotors and then varied the structure of angle on the three rotors, 0˚, 90˚ and 120˚. The dimension of the three rotors are created equal with each rotor diameter 35 cm and each rotor height 19 cm. The turbine was tested by using blower as the wind sources. Through the measurements obtained the comparisons of output power, rotation of turbine, and the level of efficiency generated by the three variations. The result showed that the turbine with angle of 120˚ operate most optimally because it is able to produce the highest output power and highest rotation of turbine which is 0.346 Watt and 222.7 RPM. </p><p><strong>Keywords</strong>: Output power; savonius turbine; triple-stage; the structure of angle</p>

ABSTRACTWind Power Plant is a power plant that uses wind as an energy resources to produce electrical energy. The Bengkulu region which is mostly a coastal area with conditions of strong wind speeds that can be utilized as a source of wind power generation. Wind energy can be utilized as an alternative and renewable energy source using wind turbine. Wind turbine performance depends on the shape, position and dimensions of the turbine, etc. In this study focus on the design of wind power plants with horizontal axis turbine position and vertical axis turbine position. Wind turbine was designed with 3 blades made of wood materials. The permanent magnet DC generator are used for generator in the horizontal axis and vertical axis wind turbine positions with maximum power that can be generated at 800 Watt. Testing of the two types of turbines was carried out on the coast of Bengkulu city. The results shows that the horizontal axis wind power plant design starts rotating at a wind speed of 3.5 m / s, while the vertical axis wind power plant design starts rotating at a wind speed of 6.5 m / s. The voltage generated by the horizontal axis wind power plant at a wind speed of 3.5 m / s is 12 Volts. The voltage generated by the vertical axis wind power plant at a wind speed of 6.5 m / s is 9 Volts.

The World

Amidst of high demand of energy, the world is seeking alternative energy sources. Wind alone can fulfill most of the energy requirement of the world by its efficient conversion into energy. On efficiency measurement, Horizontal Axis Wind Turbines (HAWT) is the popular to the researchers, but it works best in places where the wind is not disturbed and has high wind power. The inherent advantage of facing the wind direction, design simplicity, less expensive technology for construction, lower wind start-up speeds, easier maintenance, and relatively quietness are turning the focus to Vertical Axis Wind Turbine (VAWT). The low wind speed and non-smooth wind flow regions are attracted for these machines. Savonius turbine is the simplest form of VAWT and operation is based on the difference of the drag force on its blades. The main objective of this study is to analyze a perfect mixture of new and innovative designs of Savonius turbine blades, which can make VAWT more attractive, efficient, durable and sustainable. This is studied by using blade with different numbers in operating in different wind speed. A Computational Fluid Dynamics (CFD) analysis has been used. 2D CAD models of various VAWT geometries are created and tested with CFD software ANSYS/FLUENT with a similar flow-driven motion in a wind tunnel. These simulations provided the aero-dynamic characteristics like shear stress, velocity distribution and pressure distribution. Some physical models with desired properties needed to be fabricated and tested inside tunnel to find the effect of different shapes in real.

Vertical Axis Wind Turbine

The capacity of wind power generation has increased across India due to various activities encouraged by government. Moreover, onshore potential in India is in the order of 100GW. However, the plant load factor is often very low in wind power production. In most of the place, low-rated wind speed is available. Effective utilization of the wind to produce small power will reduces the grid load. There is in need to effectively utilize the available potential to meet the energy demand. The low cost vertical axis wind turbine designed for low rated wind regime has the hybrid of simple Savonius and helical Savonius. Various experimental parameters are measured to check the suitability of the vertical axis wind turbine in the low rated wind speed regions. Numerical simulation are carried out for three dimensional steady flow around the combined Savonius and helical Savonius vertical axis wind turbine blades using ANSYS Fluent(C). Numerical investigation are conducted to study the effect of hybrid combination on performance of the rotor in terms of coefficient of torque, coefficient of power, etc. Self-starting behaviour of the vertical axis wind turbine is improved by using this hybrid vertical axis wind turbine.
