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
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
 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.

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.
Background
 Whisper 200 moved to CPA location B

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 converts
DC input into single phase
120V/60Hz AC into the
electrical grid
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.
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.
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
Possible extensions
 Storage Battery system
 When output DC voltage
does not reach inverter
start point and during periods
of low wind, discharge minor
generated voltage into
batteries
 Batteries charge to capacity
then discharge into the inverter
 Downsides
 Logistics
 Cost
 Voltage losses
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
