Wind turbine maintenance is a critical part of keeping turbines running smoothly and preventing downtime. There are a number of different things that need to be done on a regular basis to keep turbines in top condition. This includes inspecting the blades for damage, checking the gearbox for wear and tear, and cleaning the nacelle.

By Windmills Tech Editor. The blades, the hub, and the main shaft of a wind turbine harness the kinetic energy of the wind and convert it into rotational mechanical energy. The speed of this rotation is too slow to drive the generator efficiently, so a gearbox converts the high-torque and low-speed mechanical energy of the main shaft into the ...

Introduction When the turbine extracts power from the wind, a wake evolves downstream of the turbine. If another nearby turbine is operating within this wake, the power output for this downstream turbine is reduced when comparing to the turbine operating in the free wind. This reduction of power output is – on an annual basis

The rotor blades capture the wind and transfer its power to the rotor hub. On a 600 kW wind turbine, each rotor blade measures about 20 meters in length and is designed much like the wing of an aeroplane. The movable blade tips on the outer 2–3 meters of the blades function as air brakes, usually called tip brakes.

In just a few tasks, electric motors pitch the blades on turbines to capture the most power from the available wind. Motors on yaw drives keep the nacelle pointed in a proper direction. Motor outputs on these units range from 2.2 to 22 kW. They attach to two or three planetary speed reducers to produce output torques from 2,000 to 50,000 nm.
