What ‘Control System’ mean for a Wind Turbine
• Yawing of nacelle• Blade pitch adjustment
![Page 3: CONTROL SYSTEM IMPLEMENTATION. What ‘Control System’ mean for a Wind Turbine Yawing of nacelle Blade pitch adjustment](https://reader036.vdocuments.us/reader036/viewer/2022062407/56649d2d5503460f94a03169/html5/thumbnails/3.jpg)
Yawing by a closed loop control system
• What was yawing?• Contents of the system– Direction sensor– Motor– Microcontroller & Circuitry

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

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