Section through the Stall-controlled TW600 Wind Generator
(600 kW Change-pole Asynchronous Generator, 43 m Rotor Diameter,
50-70 m Hub Height)
current systems reach powers up to several megawatts, whereas the wind
generators of the 1980s were in the power range below 100 kW.
A horizontal axis wind turbine generally consists of the following
components (see Figure 5.12):
•
rotor blades, rotor hub, rotor brake and if need be, a pitch mechanism
•
electrical generator and if need be, a gearbox
•
wind measurement system and yaw drive (azimuth tracking)
•
nacelle, tower and foundation
•
control, substation and mains connection.
