Amtech's windpower matrix is an IGBT
converter, which converts and transfers power generated
by
the wind turbine to the electrical power grid.
|
The turbine is coupled to two
induction generators whose
power is applied to the Matrix. The matrix
converts the
ac power of the generator into intermediate dc,
and
reconverts it to ac power at the frequency of
the grid.
This is stepped up by a transformer and connects
to
the grid.

The advantages of using an
IGBT converter :
-
The generator can be run at variable speed.
-
During gusts of wind, the rotor
can be made to run faster, thus storing this
energy as
rotational energy until the gust is over. This
also reduces peak torque, reducing fatigue
on the gear box and the rotor. This is done more
precisely and faster than can be done
by pitch control.
-
Better power quality, more
specifically a better power factor. The power
factor provided
by the windmill to the grid can be set to optimum
value required, from leading to
lagging, through unity. This allows the entire
wind farm to pose a unity power factor to
the grid, since individual windmills compensate
each other's power factor.
-
A variable speed wind mill has greater production
than fixed speed or two speed types,
due to the above advantages.
