Question

Discuss the working of windmill to produce electricity?

Answer 1

Dear Student, Winds are produced due to uneven heating of the atmosphere by the sun, the rotation of the earth and the irregularities of the earth’s surface. Wind flow patterns differs from place to place and are modified by bodies of water, vegetation, and differences in terrain. As its name states, the windmill’s only source of energy is derived from the wind. The wind turns the blades which spins a shaft, in turn, prompt a generator to produce electricity. These blades are connected to a generator, sometimes through a gearbox and sometimes directly. In both the cases, the generator converts the mechanical energy into electrical energy. Interestingly, most modern turbines turn in a clockwise direction. Depending on wind speed, most modern turbines can operate at speeds from as little as four meters per second to as much as 15 mps. Once the turbine’s blades turns a shaft located inside of a box placed on top of the turbine, gearbox mode is propelled and more speed rotation is given off. A transformer within the turbine then converts electricity into a voltage suitable for distribution to a national grid. ...Regards.
