Centrali Eoliche
Much
time makes the wind was used in order to make to move the ships and to
make to turn the shovels of the flour mills to wind. Today the
energy of the wind is transformed in electricity thanks to the wind
turbine generators, modern flour mills to wind. The places where
they come arrange the wind turbine generators to you are call Aeolic
parks and come constructed to you on the crinali of hills (in kind
between the 600 and 1500 meters of altitude), in it goes them ventose,
and off-shore, that is in means to the sea, where the wind is stronger
and regular. A particular attention acclimatizes them must be
dedicated in the study of sistemazione of the wind turbine generators
on the second land criteria of insertion in the landscape. Here
some examples: respect of the practicability already traced on
the territory, respect of the existing activities on the situated one,
sistemazione of the wind turbine generators second a perspective effect
that values the scene. It centers them eoliche are centers them
that they take advantage of the speed of the wind for the electric
power production. The operation principle is enough simple, the
module base of one centers them eolica is the Aeolic generator.
This equipment is composed from a propeller connected to a tree to
which the current generator is fastened.
The propeller and the generator are
normally places to heights high so as to to be it crosses to you from
the twenty, twenty that putting in spin the propeller they make of fact
to ruotare the generator that produces therefore energy. The
Aeolic generators can be of several dimensions and being uses you is
for a rural domestic use or in it centers them normally composed of
numerous generators. The powers of such generators vary from the
hundreds of W to the hundreds of kW. * Advantages As for
them it centers them solar those eoliche do not have residual, slags or
other by-products. The wind is gratis, therefore the only expense
is the installation and the maintenance. Content, 500,000 euro
centers them eoliche has a cost enough for a wind turbine generator
from 1 MW. It is not a lot, enough to think that for an equal
power of fotovoltaici panels they only want 6,000,000 euro to us (of
panels, to add remain the carrying structures, the cavidotti, the
inverter from 1 MW). To earth it occupies less than 100
metriquadri, therefore it does not remove the possibility to continue
the previous activities on that land (es. pastorizia...) *
Disadvantages center them to Them eoliche in order to produce
appreciable amounts of energy must be constituted from various Aeolic
generators, such generators must be maintained to sure distances for
being able to take advantage of the wind, and in order to avoid a
crowding that would be unpleasant. They can be only installed
where there is enough wind and are of the moderately noisy systems.
