  1. 1. Wind Turbine Operation and Basic Troubleshooting<br />by Tony Green <br />http://www.tonygreen.name © Tony Green 2011<br />
  2. 2. Agenda<br /> Part I - Overview of Wind Turbines<br /> Part II - Turbines<br /> What are the types of turbines? <br /> What composes a turbine? How are they related?<br />Part III – Basic Troubleshooting<br />Summary/Questions<br />http://www.tonygreen.name © Tony Green 2011<br />
  3. 3. Housekeeping matters:<br /> Cell phone in Vibrate Mode/Off<br /> Location of the heads (Bathrooms, water)<br />Questions before we begin?<br />http://www.tonygreen.name © Tony Green 2011<br />
  4. 4. Objectives of today’s presentation: <br />Understanding of what a wind turbine is and how it operates (parts, block diagram)<br />To provide a guide to basic troubleshooting<br />http://www.tonygreen.name © Tony Green 2011<br />
  5. 5. Part I -Overview<br />Why is understanding the operation of a wind turbine important?<br /> Price of oil escalating with Middle East sources/global warming CO2 emission <br />Clean/Renewable energy sources needed, wind power and solar in the mix <br />Must be reliable to keep pricing in line with conventional sources (and the lights on!), critical to keep running and if there is fault to fix it promptly <br />http://www.tonygreen.name © Tony Green 2011<br />
  6. 6. Part I – Overview<br />A Wind Turbine is machine that produces electrical power from wind<br />Source: Fundamentals of Wind Energy Alaska Wind Energy Applications <br />Training SymposiumBethel, Alaska E.

  8. 8. Part I – Overview How is energy generated?<br />Source: Creado and Sanyal Wind Energy Overview <br />Presentation via slideshare.net. <br />http://www.tonygreen.name © Tony Green 2011<br />
  9. 9. Part I – Overview<br />Whatsteps are needed to produce energy? <br /><ul><li>Blades captures wind
  10. 10. Gears adjust turning ratios
  11. 11. Generator converts rotation to Direct Current(DC)
  12. 12. Inverter converts DC to AlternatingCurrent (AC)
  13. 13. after which power can be applied to grid </li></ul>http://www.tonygreen.name © Tony Green 2011<br />

  15. 15. Wind Turbine block diagram<br />http://www.tonygreen.name © Tony Green 2011<br />
  16. 16. Part I – Overview -Energy Conversion<br />Input > Wind Kinetic Energy<br />Pressure Differential - blades are an airfoil DP provides lift/rotational motion<br />Mechanical Energy(Rotary motion) gear box as speed is increaser<br />Generator Output – mechanical to electrical<br />Output > electricity fed to grid<br />http://www.tonygreen.name © Tony Green 2011<br />
  17. 17. Question for thought…..<br />How do we track an increase in wind speed to increase power output?<br /> Answer<br />Wind speed up - blades turn faster – shaft spins faster – gears rotate faster – generator to produce higher output voltage – increase power <br />http://www.tonygreen.name © Tony Green 2011<br />
  18. 18. Part II – Turbines<br /><ul><li>Types or turbines
  19. 19. Composition of parts that make up a turbine
  20. 20. Relation of parts to each other</li></ul>http://www.tonygreen.name © Tony Green 2011<br />
  21. 21. Part II – Turbines<br />There are two types: Horizontal (HAWT) and Vertical (VAHT) <br />Source : FUNDAMENTALS, INTRODUCTION TOWIND ENERGY by<br />Ken StarcherAlternative Energy Institute West Texas A&M University March 2007<br />http://www.tonygreen.name © Tony Green 2011<br />

  25. 25. Question for thought<br />Could someone describe the operation of a simple turbine?<br />Answer<br />Wind – blades - shaft – gears – generator – inverter – transformer - consumption<br />http://www.tonygreen.name © Tony Green 2011<br />
  26. 26. Part III – Troubleshooting<br />What could possibly go wrong?<br />http://www.tonygreen.name © Tony Green 20111<br />
  27. 27. Troubleshooting - Fault I<br />http://www.tonygreen.name © Tony Green 2011<br /> Turbine slowing down with load, hard for generator to turn, more torque must be generated.<br />
  28. 28. Troubleshooting – Fault II<br /> Output Voltage Unstable/Fluctuating.<br />http://www.tonygreen.name © Tony Green 2011<br />
  29. 29. Troubleshooting – Fault III<br />http://www.tonygreen.name © Tony Green 2011<br /> Loss of output, blade not turning, no AC Power out.<br />
  30. 30. Troubleshooting – questions for thought<br /><ul><li>If you were a turbine operator who noticed that the visibly rotating by no power output what could you check first?
  31. 31. To check what is in path? Shaft, gears, generator, load. Check shaft spinning, if spin being input to generator then check output o.k., check if load connected to power </li></ul>http://www.tonygreen.name © Tony Green 2011<br />
  32. 32. In Summary:<br /><ul><li>Wind Turbine converts Wind Energy to power
  33. 33. Major components are tower, blades, gears, and generator
  34. 34. To troubleshoot it is key to under parts, their operation and relation to each other</li></ul>http://www.tonygreen.name © Tony Green 2011<br />
