  2. Wind Turbine - MAY1329 Problem Statement • Develop a laboratory module for a small wind turbine electrical system • Serve as an educational tool for students • Intake wind speed measurements and simulate the power output to the system • Continue and build upon Phase IV’s system according to the required specifications denoted by client Figure 1: System Setup Slide 2 of 20

  3. Wind Turbine - MAY1329 Market Survey • Iowa – second largest producer of wind energy in the nation • Iowa State taking steps to be environmentally friendly and self-sustainable • Electrical needs steadily increasing due to population growth in the US • Growing environmental concerns and depletion of fossil fuels • Increased production of renewable resources Figure 2 : Survey on Renewable Energy Slide 3 of 20

  4. Wind Turbine - MAY1329 Functional Requirements • Motor 1.5 Horsepower (1.1kW) • Motor has fmax of 60 Hz & Vmax of 230V • Full load of the motor is 4.08 A & 3570 rpm • Inverter input DC voltage is between 21 and 34 volts • Turbine circuitry will supply load variation up to 400 W Figure 3 : Induction Motor Slide 4 of 20

  5. Wind Turbine - MAY1329 Non-Functional Requirements • Project technical manuals and schematics documents • Motor will be remounted onto a stable operation platform • Wiring and connections done in an understandable and professional manner Figure 4 : Circuit Setup Slide 5 of 20
