How to design the wind shaft of the generator room

Why do wind turbines need a shaft?

The needed shaft relates to the additional torque and bending moment fluctuations that affect coupling and bearing support design. Such a generator placement increases the overall rotating mass, serviceability, accessibility and allows replacement without wind turbine rotor removal.

How do you use a wind turbine rotor?

Yaw the turbine into the wind and pitch the blades to zero degrees. As the rotor accelerates, adjust the generator field and electrical load to make the machine operate at a steady-state condition. Pitch the blades to 10 ° and see how your control action changes. Try to keep the speed between 200 and 400 rpm.

What is a wind turbine installation?

An installation consists of the 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.

Does a downwind turbine need a yaw mechanism?

can follow the wind automatically. Thus, the downwind turbine does not require a yaw mechanism to place the turbine in line with the wind direction and could weigh less

Can a permanent magnet generator run a wind turbine?

Alternatively, a wind turbine with permanent magnet generator can be operated as a direct-drive unit, in which the gearbox is omitted and the generator shaft is directly coupled to the main rotor shaft; this can reduce the size and weight of the nacelle, increase overall efficiency, and reduce the number of moving parts and potential for failure.

How big is a wind turbine rotor?

As of 2015 the rotor diameters of onshore wind turbine blades reached 130 meters, [ 39 ] while the diameter of offshore turbines reached 170 meters. [ 40 ] In 2001, an estimated 50 million kilograms of fiberglass laminate were used in wind turbine blades.
