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
Users ISU Student & Faculty
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
Interface
The tower mounted can’t withstand the high wind speed
Battery bank suffers complete discharge
Battery bank suffers overchargeLabView interface gets outdated and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
Update the interface and excel file. Expand its functions
