Project ObjectivesTo 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

BackgroundPrevious design group placed

Whisper 200 on Babbio roofThey 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

BackgroundA 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.

Speed

BackgroundSample 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.

Background Whisper 200 moved to CPA location B

Power Transformation SystemCurrent systemWhisper 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

Windy Boy Grid Tie InverterPower Curve OperationTurbine 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.

Issue with InverterVoltage start point set by manufacturer =

190VdcCurrently the wind turbine needs an increase

in the amount of wind speed in order to reach this point.

Inverter SolutionInverter 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

Possible extensionsStorage Battery systemWhen 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

DownsidesLogisticsCostVoltage losses

Possible ExtensionsMinor battery systemInstall 2-3 batteriesStore energy when Vdc start point is not metUse stored power in batteries to boost the

input DC voltage past the start point when it is close
