The installation consists of wind turbines, or wind generators, similar to those found on land. The difference is that these turbines are located on platforms or floating structures anchored in deep water. The turbines in offshore wind farms draw their energy from the sea ...
It is suitable for wind power generation in open plains, islands, coastal areas, etc. The power generated by small-scale wind turbines for household use is about AC 13V~25V. ...
Some details on how this can be approached is outlined in the scientific paper here (free preprint available here) which also details why high-lift airfoils are optimal for flying wind turbines/power generating kites. From 2D to 3D, and What About the Rotors? ...
Renewable Energy Search for renewable energy which would address the needs of the future has been an important issue world over. Zen Engineering has recently collaborated with various important companies locally and abroad, to supply an integrated package for generating renewable energy, based on the clients ...
The first wind turbine as we know it was created in 1888. Named the Brush turbine, an automatic wind turbine, it measured 17 m in diameter and had 144 wooden blades that moved slowly. ...
Tcharge regulation can be relatively simple: When the I-'1/batteries are full, the controller disconnects the PV r array. Adding wind or microhydro to the system makes charge regulation more complicated, since turbines may overspecd if unloaded. ...
How procurement strategies, manufacturing costs and new technology stack up against development risk in Offshore Wind Projects. Offshore wind is changing, and it is changing for the better. ...
A new bladeless wind turbine that promises to be more efficient, less visually intrusive, and safer for birdlife than conventional turbines has been welcomed by two of the UK wind energy industry’s most vocal critics. ...
Monopiles will be Europe’s dominant offshore wind foundation for the next five years despite increasing turbine capacity, Tim Fischer, Head of Wind at German consultancy Ramboll, said. ...
The technology takes advantage of vorticity to generate electricity Vorticity is a wind effect that creates a pattern of spinning vortices Bladeless design could reduce manufacturing costs by 53 per cent Prototype ‘Vortex Mini’ can capture nearly half of the wind’s power Today’s wind ...
As with solar, the credit goes to technological advances and volume increases. For wind, however, innovation has mainly been a matter of size. From 1981 to 2015 the average length of a wind turbine rotor blade has increased more than sixfold, from 9 meters to 60 meters, as the cost of wind energy has dropped by a factor of 10. ...

2015’s official Wind Energy Forecast for the South African market was released today detailing the key market trends in 2015 for wind energy in in the country. ...
Using the Lagrange principle, the nonlinear dynamical equation of wind turbine generator drive system is presented, which considers nonlinear stiffness of the drive system. The stability of autonomous system is analysed by the Jacobian matrix. The stability of wind turbine generator drive system ...
In five U.S. states, however, 10 percent or more of electricity generation came from wind. South Dakota leads the states, with wind power making up 22 percent of its electricity generation in 2011, up from 14 percent in 2010. In 2011, Iowa generated 19 percent of its electricity with wind energy. ...
A huge number of wind generators are going to be connected with the existing network in the near future. ...
This paper investigates the operation and control of multiple Distributed Generation (DG) systems interconnected to the utility in the form of microgrid. The developed model of the microgrid consists of microturbine generation system, converter-based DG system with stiff DC source, synchronous-generator-based DG system and wind ...
This paper deals with a wind energy conversion system (WECS), based on a doubly fed induction generator (DFIG) and an electromechanical active power filter (APF). ...
The main objective of the study is to estimate wind power potential of Turkey and provide suitable data for evaluating potential wind power by using the wind data collected at 23 different wind-monitoring stations. In this study, energy and exergy analyses of wind power are used to estimate wind ...
Suzlon Energy (Pune, India) and Vestas Wind Systems A/S (Randers, Denmark) have announced new orders for wind turbines and associated equipment, in Vestas’ case the first European orders for its new V112 3-MW model. ...
