Wind power generation is power generation that converts wind energy into electric energy. The wind generating set absorbs wind energy with a specially designed blade and converts wind energy to mechanical energy, which further drives the generator rotating and realizes conversion of wind energy to electric energy.
Rain and lightning strikes can damage turbines, too. When a typhoon approaches, a wind farm often shuts down its turbines through a remote-control system once the wind speed reaches their operational limits, according to Han Yujia, a renewable energy researcher at Global Energy Monitor (GEM), a California-based non-profit.
The installation produces electricity by collecting and transforming wind power into rotational mechanical energy to drive a generating unit. Wind power generation technology is now relatively mature, with annual generation amounting to 640 TWh, accounting for less than 3% of the world's total energy consumption.
Introduction of wind power generation has been increasing in the world, which has the following characteristics: In the world today, progress of technologies to develop larger WTGs are remarkable, and it makes electric output per one WTG unit increased and large field of WTGs called "wind farm" has developed.
