Title: Small Scale Wind Turbines Optimized for Low Wind Speeds
Creators: Letcher, Todd
Advisor: Shen, Herman
Issue Date: 2010-05
Abstract: A combination of common vertical axis wind turbines (VAWT) rotors was designed and tested for optimal performance in low wind speeds. The Savonius rotor creates high torque and is self-starting even at low wind speeds, but is relatively low in efficiency rating. The Savonius rotor is used to start the straight bladed Darrieus rotor. The Darrieus rotor is not a self starting rotor, but has much higher efficiency than the Savonius rotor. The combination of rotors increases the total power of the turbine in lower wind speeds.
