Working principle of Jifengli wind power generation
Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn. The blades are connected to a drive shaft that turns an electric generator, which produces. . Wind Turbine Definition: A wind turbine is defined as a device that converts wind energy into electrical energy using large blades connected to a generator. Wind is a form of solar energy caused by a. .
