Rooftop Wind Turbine Wind Turbine Type and Shape Aerofoil Design Electrical System Roof Bracket Design Final Results
Wind Turbine Type Wind conditions: Low / Turbulent Darreius is efficient in turbulent winds Savonius is self starting Chose a combination Darreius/Savonius wind turbine
Electrical System Net Metering Indirect Grid Connection Grid Connection System Typical Appliance Power Usage
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.
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
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
