★ ★ ★ ★ ☆

Wind turbine design is the process of defining the form and specifications of a wind turbine to extract energy from the wind. A wind turbine installation consists of the necessary systems needed to capture the wind's energy, point the turbine into the wind, convert mechanical rotation into electrical power, and other systems to start, stop, and control the turbine.

This paper presents a method to control the rotor speed of wind turbines in presence of gearbox efficiency fault. This kind of faults happens due to lack of lubrication. It affects the dynamic of the principal shaft and thus the rotor speed. The principle of the fault tolerant control is to find a bloc that equalizes the dynamics of the healthy and faulty situations.

Simply stated, wind turbines work the opposite of a fan. Instead of using electricity to make wind—like a fan—wind turbines use wind to make electricity. The wind turns the blades, which in turn spins a generator to create electricity. To see how a wind turbine works, click on the image for an animated demonstration. How Wind Creates Energy

When V < V cut–in, the wind is not strong enough to move the blades.In the partial load zone, range of speeds between the cut-in speed and the rated one, the control objective is maximising the energy conversion efficiency.In the full load zone the controller must limit the extracted power to its rated value. Finally, above ν cut–out speed the turbine should be turned out of the wind to ...

8/7/2011 · The efficiency of any turbine or engine can be defined as its ability to convert the input energy into useful output energy which is expressed in the form of the following equation.. Efficiency (ɳ) = Output / Input. An ideal turbine with 100% efficiency is the one which converts all its input energy into output work without dissipating energy in the form of heat or any other form.

When the wind blows, the turbines rotate, turning the wind into energy for communities to use. But in order for the wind turbine to produce the greatest amount of energy efficiently, a wind turbine service technician must inspect, troubleshoot, repair, and ensure that the wind turbine is in good working order.
