Modern wind farms comprised of horizontal-axis wind turbines (HAWTs) require significant land resources to separate each wind turbine from the adjacent turbine wakes. This aerodynamic constraint limits the amount of power that can be extracted from a given wind farm footprint. The resulting inefficiency of HAWT farms is currently compensated by using taller wind turbines to access greater wind ...

Wind turbine is a technology which converting wind energy to electric power. Wind energy is easily accessible anywhere in the world and is one of renewable energy. However, in Kuala Terengganu, the lower average wind speed become one of the factors wind turbine has not been used widely as alternative method for generating the electric power. Thereby, small scale wind turbine which can generate ...

Due to the diminishing reserves of fossil fuels and increased pollution from exploitation of these fuels, the world is focusing on the renewable energy sources. Wind is being considered as one of the prime next generation energy sources. Considerable amount of research is being carried out on the innovative designs for maximizing the performance of wind turbines. Furthermore, a lot of research ...

This case study investigates the generator of a large offshore Vertical Axis Wind Turbine (VAWT). In particular this case study focuses on the effect of the inherent cyclic torque loading of the VAWT on the generator in terms of the costs and losses experienced. A spectrum of torque control strategies were created based on the ratio q of the allowed electrical torque variation to the mechanical...

Rapid decrease in the fossil fuels in the last couple of decades has stirred the researchers to find alternative sources for the production of power. Wind and tidal energies are the two most promising alternatives to the fossil fuels. While most of the recent research has been conducted on developing electro-mechanical systems for power production from wind energy, the research regarding the us...

An experimental campaign of measurements for a Darrieus vertical-axis wind turbine (VAWT) is presented for open field conditions. The turbine is characterized by a twisted bladed design, each blade being placed at a fixed distance from the rotational shaft. The experimental setup to perform the acquisitions is described. The results are lower than expected, due to the high influence of the wind...

A new computational model for the analysis of the suspension system of an innovative concept in vertical-axis wind turbines is introduced. We used this model to study a new concept in extra-large wind-power plants: the VGOT (variable-geometry oval-trajectory) Darrieus wind turbine. In a traditional Darrieus turbine, the blades rotate around a central vertical axis. In the VGOT concept each blad...

Vertical Axis Wind Turbines (VAWTs) are not mature enough yet for offshore wind farms, but they offer benefits compared to conventional Horizontal (HAWTs). Higher power densities, reduced wakes, lower center of mass, and different thrust curves make VAWTs an interesting option complement existing farms. The optimization farm layouts—finding the optimal positions turbines in a park—has proven cr...

Energy is an important aspect of our everyday life. The resources we use are limited whereas the population consuming same increasing day by day. Nowadays requirement for electricity much higher than its generation; hence main objective work to produce at low cost with no effect on environment. design a wind turbine recapture energy from vehicles highway. A considerable amount produced due pres...
