  4. Project Objectives • To design a monitoring system to record data from the wind turbine and use this data to improve on the power generation . • Design and build a foundation to raise the height of the turbine over any further obstacles and bring it closer to the recommended height. • Use the monitoring system to observe vibrations transmitted by the turbine into the roof slab. • Design the foundation in response to vibrations analysis • Analyze the data to study trends of a wind turbine in an urban environment

  5. Background • Previous design group placed Whisper 200 on Babbio roof • They incorrectly assumed wind readings from buoy on Hudson river and other local weather stations were similar to Babbio roof conditions • Local wind measurements were needed of potential locations on campus for the Whisper 200

  6. Background • A repeatable experiment was executed at 8 locations on Stevens Campus • Measured wind speeds and direction. • Repeated on three different days • Sample was taken at Babbio Location A (original location) on Day 1 between 1:35pm and 1:45pm.

  7. Background • Sample was taken at CPA Location B (optimal location) on Day 1 between 3:00pm and 3:10pm. • Average Wind Velocity was measured to be 4.0408m/s. • Wind Direction was conclusively consistent. • After analysis, this location was chosen as the most optimal for the Whisper 200, due to its constant wind direction and reliable wind velocity.

  8. Background • Whisper 200 moved to CPA location B

  9. Monitoring System • Live remote monitoring • Vibration • Power production • Wind behavior • Video feed • Store data to create archive of Whisper 200 performance characteristics • Post results on website

  10. Monitoring System • Parts Ordered • 2 Accelerometers • USB data logger • USB to Ethernet Microserver • Programming Needed • Labview • Sensors signal processing • Website • Easy display of data • Live video feed

  11. Power Transformation System • Current system • Whisper Link – Rectifies the 3 phase AC out of the turbine and supplies the inverter with a DC output voltage. • Windy Boy Inverter convertsDC input into single phase 120V/60Hz AC into the electrical grid

  12. Windy Boy Grid Tie Inverter • Power Curve Operation • Turbine mode of operation draws power based upon the DC voltage seen at the input terminal. • Maximum power output 1800W • When start voltage is reached, the inverter waits 10 seconds • If voltage remains above start point , inverter will synchronize the power and export it. • If voltage drops below set point ,inverter will have a zero power output for 120 seconds before shutting down.

  13. Issue with Inverter • Voltage start point set by manufacturer = 190Vdc • Currently the wind turbine needs an increase in the amount of wind speed in order to reach this point.

  14. Inverter Solution • Inverter can be adjusted with software provided by manufacturer and purchased connecter cable. • Software allows for adjustments to the slope of the power curve • Able to reprogram voltage start and max point in range of 155 – 375 Vdc • By reducing start and max point, you reduce the maximum power output

  15. Possible extensions • Storage Battery system • When output DC voltage does not reach inverterstart point and during periods of low wind, discharge minorgenerated voltage into batteries • Batteries charge to capacity then discharge into the inverter • Downsides • Logistics • Cost • Voltage losses

  16. Possible Extensions • Minor battery system • Install 2-3 batteries • Store energy when Vdc start point is not met • Use stored power in batteries to boost the input DC voltage past the start point when it is close • Downsides • Cost • Logistics • Feasibility
