The wind turbine technology is now a developed technology. Modern wind technology incorporates each aspect of grid integration, stability and power quality issues in the arena of reliable power production to user end or utility. The paper provides cumulative modernization of wind turbine technology through literature survey of wind turbine configurations followed by discussion of different cont...

A permanent magnet synchronous generator (PMSG) variable speed wind turbine connected to an electrolyzer and a battery model system is presented in this paper. Hydrogen gas could be produced from the model system, when a variable wind speed is applied to the PMSG driven variable wind turbine. The simulation results presented shows the nature of some of the variables of the PMSG wind driven turb...

Turbulent wake of wind turbine will reduce the power output of wind farm. The access to real turbulent wake of wind turbine blades with different spatial and temporal scales is provided by the pulsed Coherent Doppler Lidar (CDL) which operates by transmitting a laser beam and detecting the radiation backscattered by atmospheric aerosol particles. In this paper, the authors discuss the possibili...

Vortex generators are devices that modify the wind behavior near surface of turbine blades. Their use allows boundary layer shedding transition zone to be varied. Bio-inspired design has been used improve efficiency aerodynamic and hydrodynamic systems by creating shapes present in animals plants. In this work, an experimental methodology is proposed study effect bio-inspired vortex their on st...

Noise generated by wind turbines has been reported to affect sleep and quality of life (QOL), but the relationship is unclear. Our objective was to explore the association between wind turbine noise, sleep disturbance and quality of life, using data from published observational studies. We searched Medline, Embase, Global Health and Google Scholar databases. No language restrictions were impose...

Some large wind turbines use a low speed synchronous generator, directly-coupled to the turbine, and a fully rated converter to transform power from the turbine to mains electricity. This paper considers the condition monitoring and diagnosis of mechanical and electrical faults in such a variable speed machine. The application of wavelet transforms is investigated because of the disadvantages o...

Wind farms are a new source of environmental noise. The impact of wind turbine noise on health and well-being has not yet been well-established and remains under debate. Long-term effects, especially, are not known, because of the short time wind turbines have been operating and the relatively few people who have so far been exposed to wind turbine noise. As the rate of new installations increa...

This experimental study was conducted in a wind tunnel using two turbines in tandem arrangement and downstream turbine is located at X/D=2. The purpose was to investigate how yawing the upstream turbine will affect the performance of the downstream turbine as well as the upstream turbine. Wind loading (thrust force), rotational frequency and power output are the parameters used to define the pe...
