  1. Rooftop Wind Turbine Greg Pawlus Biem Andrew Thon Matthew MacCormack Bryan MacDonald

  2. Rooftop Wind Turbine Wind Turbine Type and Shape Aerofoil Design Electrical System Roof Bracket Design Final Results

  3. Wind Turbine Type Wind conditions: Low / Turbulent Darreius is efficient in turbulent winds Savonius is self starting Chose a combination Darreius/Savonius wind turbine

  4. Aerofoil Design

  5. Electrical System Net Metering Indirect Grid Connection Grid Connection System Typical Appliance Power Usage

  6. Net Metering Program in place to allow residents to produce and sell power to the grid. Allows residents to meet partial energy needs from renewable sources while still being able to draw from power grid.

  7. Net Metering Requirements: Bidirectional Meter Normal Voltage Condition: 110/220 – 125/250 Extreme Voltage Condition: 106/212 – 127/254 Total Harmonic Distortion: 5% Frequency: 59.7 Hz – 60.2Hz Grid disconnect during power outage

  8. Indirect Grid Connection Generator cannot be connected to the power grid directly Three-phase rectifier produces a DC voltage Voltage regulator outputs constant voltage Inverter produces single phase AC signal with constant frequency

  9. Grid Connection System Generator Rectifier / Brake Switch Inverter / Controller

  10. Generator Choose a PMG rated at 1000 watts at 350 RPM

  11. Rectifier/Brake Switch WindyGirl Voltage Limiting Rectifier: Shorts the generator above 400 volts to electrically brake the turbine. Provides a manual brake switch

  12. Controller/Inverter Monitors the generators output to ensure the required standards are met. Monitors grid for power outages. SMA WindyBoy 1700
