The ANTARIS 9.5 kW is a small-wind turbine with
horizontal rotor axis for generation of electric energy (see picture
1). The rotor, from wind direction, here is located before the mast
(upwind arrangement). Three glass-fibre/carbon-fibre rotor blades
directly drive a permanent magnet activated three-phase alternator.
The generated electricity is directed to the tower base via vertically
arranged ring wheels and a flexible cable. A wind vane orients the
turbine according to the wind conditions. The ANTARIS features a
flange at the swivel due to which it is possible to set up the turbine
on various mast systems. At a certain wind velocity the rotor tilts
upwards into the helicopter position and with this limits the power
by decreasing the circular area.
Safety Shutdown Mechanisms
During a storm the turbine independently tilts upwards into the helicopter position and with this decreases the target for the wind and limits the energy intake through the wind.
This braking system is also effective when no load is connected to the alternator.
On reaching the warning speed the turbine speed is reduced through additional usage of braking resistance via the controller.
On reaching the error speed the turbine speed is reduced until the turbine stops. The turbine resets automatically after 2 hours.
Using the manual switch on the controller, the turbine speed can also be reduced through braking resistances. After speed reduction the alternator can be short-circuited via the main brake switch.
