Course Overview

This course uses the engineering skills learned in prior courses as a springboard to deepen students’ practical knowledge of the interaction between aerodynamics, loads and controls during turbine design. During the semester, students work in groups to redesign the DTU 10 MW Reference Wind Turbine for a different wind class. The following topics are covered: methods for redesigning a wind turbine rotor, wind turbine control basics and controller tuning, wind turbine dynamics and aeroelastic mode shapes, lifetime load calculations (fatigue + extreme), wind turbine certification standards and more.

MAIN GOAL

To give the students advanced competencies in modelling and analysing the structural dynamics, aerodynamics, aeroelastic characteristics and control of wind turbines using analytical and computational methods, thereby creating a basis for evaluating the loads-performance trade-off during wind turbine design.

Learning Outcomes

After completion of this course, you will be able to:

• + In a team, aerodynamically redesign the rotor of a reference turbine for a different wind class and evaluate the quality of the resulting design.
• + Evaluate how the design’s aeroservoelastic response affects turbine production and lifetime loads and hypothesize how the design could be improved.
• + Explain the wind turbine control objectives and how a controller is designed to achieve these objectives.
• + Calculate the structural, aeroelastic and aeroservoelastic modes of an operating wind turbine and explain the differences between them.
• + Tune a wind turbine controller and evaluate its performance with an aeroelastic simulation code.
• + Explain how the different parameters such as tip-speed ratio, lift-drag values and the lift coefficient affect the aerodynamic design and performance of rotors.
• + Explain which external loads affect a specific load channel in the turbine and sketch the mean loads versus wind speed.
• + Simulate, plot and analyse a standard design load basis for a redesigned turbine and use it to calculate lifetime loads.
• + In a team, design and utilize a Python package hosted on GitHub to generate input files for aeroelastic software.
• + Present knowledge in writing related to aeroservoelastic wind turbine design.
