 The
Energetic Drives team has put together an energy generation turbine
system. The target market for our small turbines are schools,
small office buildings, farmers and large residences.
Our
turbines consist of 60 to 90 foot latticed towers upon which a nacelle
sits. In the nacelle we provide a direct drive water cooled permanent
magnet AC generator (see Fig. 1) coupled to a braking system.
There is no gearbox in this design providing a low maintenance, high
efficiency power generator.
 Each
system has its own grid tie inverter (see Fig. 2) that is
mounted in a weatherproof NEMA 4 enclosure or can be mounted on a skid
for placement in a water proof structure on site within 150 feet of the
generator.
The
turbine provides clean 480 volt 3 phase power for your own use (230
volt 3 phase is optional). If a
net metering policy is offered by your local utility company, all
energy not consumed may be sold back to your utility company or
credited to your bill when the turbine is not producing due to wind
conditions.
All
turbines are controlled by a small programmable logic controller and
have a touch screen panel for local monitoring and control.
Additional features include Ethernet access from the location of your
choice. All systems have multiple levels of password
protection
for your security.
There
are a number of design
options when considering the tower and blade structure. You will notice
in Fig. 3 a lattice tower with a blade/ rotor system
being guided by a fin to an optimum wind generating position.
When
the wind energy exceeds the system parameters, our control system will
automatically drop out of production until normal conditions are made
at which time the system awakes from the dormant / safe mode to active
production of energy in minutes. This closed loop control system is
provided through an on board anemometer feedback circuit that makes
decisions based on the wind.
Another design is an enclosed tower structure (see Fig. 4) with an
enclosed
nacelle that houses the permanent magnet generator and brake hardware.
The nacelle and rotor structure is directly coupled to a rotary axis
called the
yaw axis. This design provides more control of the turbines power
generation
range. At the low end of the wind energy
range, a signal can be sent from the anemometer to the controller to
start up
the yaw drive and position the rotor such as to optimize the efficiency
of the
blades. This allows the turbine to produce energy at lower wind speeds
than
discussed above.
