In 2008 President Geoffrey introduced the
Live green program which called for
environmentally conscious living. In light of
this initiative, it was decided to actively
assemble a wind turbine that would supply
power to Coover hall and reduce our carbon
footprint

The goal of our project is to install and implement a
wind turbine system into the Coover Hall grid. The
system is designed to produce 1200 watts when all
phases are completed but during our phase the
output will be 400 watts. The turbine is an AIR X
permanent magnate generator. The inverter is an
OUTBACK grid tie inverter with a capacity of
2500VA. Our design focused on sensing and
outputting values from the circuit.

Produce 400 watts of electrical energy to the Coover
Grid at 120 volts with a 60 Hz frequency
Convert turbine DC voltage to useable AC voltage
Sensing circuits read DC and AC voltages and
currents
Sensing circuits send information to display on a
computer using LabView
Protect batteries from total discharge
Turbine is mounted high enough to receive non
turbulent wind
All wiring and electrical work complies with
university and state electrical codes and regulations
 Battery bank is in controlled temperature and stable
environment
 Tower mounting complies with building standards
 Turbine is mounted high enough to allow
maintenance to walk under turbine

AirX turbine capable of producing 400 Watts
Outback inverter capable of converting 2500VA of
DC to AC
 Sensing circuitry that can sense DC and AC voltage
and current
 LabView interface capable of output sensing
circuitry inputs

Uses
 Research
 Class Work
 Showing to prospective students
To ensure the sensing circuitry was working
correctly we simulated each circuit individually and
tested it with the LabView interface
 Testing the turbine we made sure the turbine
control would work as specified to prevent
overcharge on battery bank
 Wired up the inverter to check if the DC was getting
fully converted to AC

An NI 6008 DAQ is used to display the chosen
parameters
 The device takes its inputs from the sensors
 The DAQ connects to a computer which displays the
parameter values and their waveforms using
LabView
 These values are then stored in an Excel
spreadsheet for future reference

The tower mounted can’t withstand the high
wind speed
Battery bank suffers complete discharge
Battery bank suffers overcharge
LabView interface gets outdated and not
sufficient

Tower will be mounted by professional
Inverter has a charger to prevent total
discharge
Turbine has controller that will not allow
overcharging
