The design, construction and performance analysis of a portable vertical axis wind turbine (VAWT) generator
Main Article Content
Abstract
The increase demand for electric power, high consumption and little power station capacity has caused to reduce supplying hours of electricity in Iraq. Furthermore high bills prices especially in rural areas and cities faraway from electricity-generating power stations. In addition to the increase in pollution due to the use of fossil fuel sources. All those obstacles have led to the search for cheap, clean and renewable energy sources. In this research, wind turbine model operates at a low wind speed and high efficiency was achieved. The model was located and studied in Tikrit city where wind power need to be consumed. Here, the vertical turbine with an area of 0.49 m2 was designed and then it was placed at least 8 meters above the ground without any disturbances within 100 meters in any direction. The system was observed to start rotating with wind speed of 1.5 m/s. However, the best turbine cycles per minute were 68 was obtained at wind speed of 6.6 m/s and the system torque was 60 N.m. Finally, 75 watts of power was produced from a multipurpose generator that was designed to run a single battery. and was used (Neodymium magnet), and also operated at low speed.
