Course information

In this section an example of a typical course is shown.

Course content

An introduction to frequency based stability analysis of a wind turbine using the aeroelastic stability tool HAWCStab2. Furthermore, new and future features are presented.

Learning objectives

The course should enable the participant to:

- Set up a HAWCStab2 model for computation of a wind turbine. This includes correct input of geometry, structural and aerodynamic data and control.

- Perform structural, aeroelastic and closed loop modal analysis of a wind turbine.

- Tune a pitch variable speed control algorithm to the turbine.


Day 1


Welcome and Introduction

Introduction to HAWCStab2 and underlying assumptions as well as introductory exercises

12.00-13.00 Lunch
13.00-17.00 Aeroelastic instability theory and exercises

Day 2

Structural and aerodynamic input files in HAWCStab2 and sensitivity analysis exercises
12.00-13.00 Lunch

Open- and closed-loop modal analysis and comparison with data from time series

Future work e.g. N-bladed turbines and various foundationse.g. floating and jacket

Practical information

Participants are expected to bring their own laptop computers for performing exercises. Matlab, Python, GnuPlot or/and Excel can be used to visualize computed data.
