  1. CONTROL SYSTEM IMPLEMENTATION

  2. What ‘Control System’ mean for a Wind Turbine • Yawing of nacelle • Blade pitch adjustment

  3. Yawing by a closed loop control system • What was yawing? • Contents of the system • Direction sensor • Motor • Microcontroller & Circuitry

  4. Yawing by a closed loop control system • Direction sensor

  5. Yawing by a closed loop control system • Motor

  6. Yawing by a closed loop control system • Microcontroller & Circuitry • PIC 16F877

  7. Blade pitch adjusment by a closed loop control system • What was pitch adjustment? • Contents of the system • Linear position sensor • Motor • Microcontroller

  8. Blade pitch adjusment by a closed loop control system • Motor

  9. Blade pitch adjusment by a closed loop control system • Linear position sensor

  10. Sensors used in control system Three types of sensors: Angular direction sensor for yawing Linear position sensor for pitch adjustment Angular resolver for speed measuring

  11. Sensors used in control system Angular direction sensor for yawing

  12. Sensors used in control system Linear position sensor for pitch adjustment

  13. Sensors used in control system Angular resolver for speed measuring

  14. Motors to be used • Step motor with high torque • High torque  High Current • DC motor with a gear box • Needs additional device for feedback

  15. Putting all together
