The purpose of
variable pitch control
The leaf
angle
in a certain range
(0
degrees ---90
)
,
in order to adjust the
output
Power
,
avoid
fixed pitch
units
in determining the
angle of attack
,
may have
low
power
in summer
, And winter super fat.
At low wind speed
,
power
optimization
,
better
The wind energy into electric energy.
Control strategy
for
variable pitch
unit
:
1-
below the rated wind speed
by controlling
the rotational speed of the generator
so that the
tracking
speed,
so you can Optimal tracking
Cp
;
2- above the
rated wind speed
by
the speed controller
and
variable interaction
paddle controller
,
making
power
The rate
is relatively stable
,
the torque
power
curve is better
.
The wind speed is below the rated
stage:
to achieve the
main goal
is to make
as much as possible
to absorb
more
wind
impeller
.
The bigger the Cp
,
the more
wind energy
absorption
.
Because
the wind speed is below the rated
wind speed
is small
,
therefore
,
there is no need to
pitch
at this time
,
this will
only need to
set the minimum
angle of the blade
pitch
angle
regulation
.
Above the rated wind speed
:
while playing the role of
speed
controller and
pitch controller
.
The
speed
controller of the generator
is
controlled by
the
constant
torque
and
constant power
.
Through the pitch
adjusting
the rotational speed of the generator
,
which
always
set point
tracking speed
.
