  1. Wave Power Generation Team 7

  2. Team 7 • Stephanie Beaton • Keith Gillis • Mark Larade • Eric Sharp • Yves Sharp • Supervisor: • Dr. Marek Kujath

  3. Project • Demonstrate the ability to generate electrical power from ocean waves • Design and test a device in real world conditions • Evaluate the success of the device

  4. Agenda • Final Design • Simulation • Testing • Results • Analysis • Scalability • Efficiency • Budget • Conclusions • Questions

  5. Design • Buoy Action • Power Generating Buoy & Foam Base • Return Buoy • Moorings

  6. Design • Power Generating Buoy (Inside) • Main Pulley • Generator

  7. Design • Power Generating Buoy (Inside) • Generator • Pulley

  8. Design • Drive Train • Main Pulley • Shaft • Rope

  9. Design • Drive Train • Pulley • Rope

  10. Design • Electrical Generation and Transmission • Multi-meters • Light Bulbs

  11. Simulation • Working Model Overview • 2D Dynamic Model • Inputs: Wave Frequency, Wave Height, Wave Drag Wind Force, Return Force, Return Drag • Wave Motion Modeled Using an Actuator: - wave height and sin(2*wave frequency*π*time) • Illustrated the motion of device and influence of wind on the operation

  12. Simulation • Working Model Results • Limitations - Main buoy constrained - Unable to specify rope diameter - Graphical display • Ideal placement of two buoys when testing on open water

  13. Testing • Blind Bay, NS • 15m from shore • 15m water depth • Below average wave height

  14. Testing • Initial Leak Testing

  15. Testing • Buoy set-up • Test 1

  16. Testing • Electrical Measurements • Marine cable run from boat to buoy • Measured amperage, voltage • Lit light bulb

  17. Testing Summary • Motion in Ocean Waves • Return Buoy • Functioned as expected • Cable Tangling • Not observed • Power Generating Buoy • Needed added buoyancy to follow low amplitude waves • PowerProduced

  18. Testing • Demonstration – On Shore Pull Test

  19. Generator Testing

  20. Analysis

  21. Analysis • Efficiency • From wave to buoy

  22. Analysis • Scalability • Froude Number Ref: Wave Energy: a design challenge (Ronald Shaw)

  23. Analysis • How big a buoy to get a kW • 5.5m ∅ • How many buoys to power a house? • 40

  24. Analysis • Budget • Under budget • Some components were free • Locally sourced components

  25. Conclusions • Comparison to Requirements

  26. Conclusions • Strengths • Adaptable to different wave heights and tides • Design uses off the shelf components • Simple construction • Works well mechanically

  27. Conclusions • Weaknesses • Difficult testing • Marine growth will require periodic cleaning • Larger waves needed • Intermittent power production • Low efficiency

  28. Conclusions • Possible Design Changes • Use non-stretching rope for better response • Placing handles on the buoy • Test in tropical location • Place generator on ocean floor • Consider more closely the effects of friction
