The course Wind Energy Technology II (WET II) is the second of two modules that introduce to the technology of wind turbines. It builds upon WET I and deepens the competences and the knowledge gained therein. The course is subdivided into lectures, tutorials, and an additional unmarked achievement.

Highlight: Loads Simulation

In the accompanying tutorials, loads simulations are carried out in WET II using coupled aero-servo-elastic simulation codes. The simulation results are afterwards analysed and interpreted. By doing so, students develop basic understanding of the very complex dynamics of a wind turbine system. Moreover, they train skills in simulation technology and data evaluation – both crucial topics in the context of digitalisation and industry 4.0. In the context of loads analysis, students take an additional unmarked achievement.

Learning Objectives

Students gain manifold insights and deepened competences in the area of wind energy technology. After successul completion students are able to

  • name and explain dynamic effects in wind turbines,
  • calculate (with limitations) the structural dynamics and natural frequencies of wind turbines,
  • explain the unsteady blade element momentum theory,
  • parameterise wind turbines and certification load cases with appropriate software,
  • calculate and interprete loads acting on wind turbine components in the context of full turbine simulations of selected load cases,
  • carry out a fatigue analysis for given boundary conditions,
  • explain the loads acting on offshore wind turbines,
  • explain the functionality of floating offshore wind turbines,
  • evaluate the processes of integrated turbine design,
  • explain the functionality of vertical axis wind turbines.


The lecture of WET II contains the following topics:

  • Structural dynamics of wind turbines
  • Unsteady aerodynamics of wind turbines
  • Loads simulation and certification
  • Concepts of fatigue design
  • Loads on offshore wind turbines
  • Floating turbine concepts
  • Vertical axis wind turbines
  • Integrated turbine design

Tutorial and Unmarked Achievement

In the tutorials of WET II, students immerse themselves in the lecture topics. The tutorials contain interactive units, in which students solve problems independently (with supervision), and units in the CIP pool. The highlight is the introduction to coupled aero-hydro-servo-elastic turbine simulations with OpenFAST. Specific software skills are not required.

In the additional unmarked achievement, students carry out turbine simulations of a given wind turbine model independently. On the basis of selected load cases, students learn to analyse and interpret wind turbine dynamics. Hence, the unmarked achievement also assists in the preparation of the exam.

Exam Modalities

To successfully complete the course, students have to pass an oral exam. The oral exam has a duration of approximately 20 minutes. In the oral exam, students need to explain the theoretical background of the different topics discussed in the lectures and the tutorials. Theoretical derivations are also part of the oral exam.

Students have to register to the exam in due time at Akademisches Prüfungsamt (APA). In addition to the oral exam, students need to complete the unmarked achievement, for which online registration is also required.

Changes in the Master's studies "Energy Technology": Students receive 5 CP. In order to reduce the work load respectively, the content of the unmarked achievement is reduced. Details are communicated during the lectures.
