wind energy plants are based on a horizontal axle, similar to a
propeller. They consist of rotor/generator, frame/azimuth bearing
and a wind vane. The rotor blades are made of fibreglass strengthened
raisin (GFK) because this material provides the necessary stability,
as well as flexibility and low weight and it does not interfere
with HF signals (radio, TV). Permanent magnet generators are high-performance,
even though they are small and light as they work with stator windings
only. Directly powered generators are robust and safe as there is
no need for a gear and shaft assembly or belt drive. The wind vane
keeps the rotor in the wind and is conceived as part of the storm
safeguard elements.
The
mast is an indispensable part of a complete wind energy plant. Turbulences
decrease with increasing height, while wind force increases with
height.
