Anemoscope system, how does it work?
Wind
speed is monitored by an anemometer & dogvane similar to weather
monitoring stations. The controller uses this
information to manage the turbine furling in all wind conditions. The turbine head is motorised and can rotate through 360 degrees.
As wind speeds increase the rotation speed is
controlled by rotating the head to 30 degrees, 60 degrees and finally if
wind speeds increase further the head turns to 90 deg off the wind to
slow blade speed.
The
turbines are designed to withstand up to 100 mph winds. The
system can also be controlled manually if required.
The
advantages over conventional furling systems using electro-mechanical
braking, jointed sprung blades or tails is there
is simply less to go wrong.
The rotating head
uses a concealed motor with a worm drive. No need for gearboxes or
electro mechanical braking systems.
Fixed fibre
glass blades are stronger and lighter than steel and have better
durability, requiring less maintenance and resulting in higher efficiency and quieter
running.
Battery systems use maintenance free modern long life battery banks
which means that energy can be stored for use at peak times
making them ideal for UPS and 24/7 power backups for stand alone
generator systems cutting payback times significantly.
On Grid installations do not require batteries.
