4 FAQs about What are the wind shafts in the generator room

How do wind generators work?

Wind generators operate on the principle of converting kinetic energy from the wind into mechanical energy, which is then transformed into electrical energy. Wind moving over the earth's surface possesses kinetic energy due to its mass and velocity. When wind passes through the blades of a wind turbine, it exerts force, making the blades spin.

How does a wind turbine gearbox work?

Basically, the gearbox accelerates the speed of rotation of the high-speed shaft to the levels necessary to generate high-voltage electricity with the generator. The gearbox is a costly (and heavy) part of the wind turbine and engineers are exploring “direct-drive” generators that operate at lower rotational speeds and don't need gearboxes.

Should a generator air inlet be facing the wind?

When ever possible, face the generator air inlet openings away from the wind. The wind can prevent the air intake louver from opening on start up. The air inlet must be capable of moving enough air through the room to provide the correct minimum CFM (cubic feet per minute) cooling for generator as specified by the generator's manufacturer.

How does a wind power plant work?

In a utility-scale wind plant, each turbine generates electricity which runs to a substation where it then transfers to the grid where it powers our communities. Figure 1. Wind Power Plant Transmission lines carry electricity at high voltages over long distances from wind turbines and other energy generators to areas where that energy is needed.
