Components of a wind turbine

Finn Gunnar Nielsen explains the main components of offshore wind turbines and illustrate how wind energy is converted into electrical energy.

To have a precise communication about wind turbines and their main components, a common name convention is important. In this lecture, the commonly used names of offshore wind turbines are explained. Also, the two most common principles for the conversion of the wind turbine rotation into electrical power is introduced. These principles will be explained in more detail later in the course.

Learning outcome.

  • Knowledge of the names of the main components of an offshore wind turbine.
  • Knowledge about the main difference between a HAWT and a VAWT.
  • Knowledge about the difference between a geared generator and a direct drive generator.

After having watched this video, search the internet and

  • See if you can find other names on the main components.
  • List names of other components, in particular related to the “drivetrain”.
  • Reflect on the fact that the nacelle weight per MW tends to increase as the size of the turbine increases.
