This project is intended as a Master's project for students with a background in control, sensing or mathematical modelling.
As part of the project it is encouraged for the student to spend 1-2 weeks at Vestas R&D headquarters in Aarhus.
All commercially successful wind turbines
have been horizontal axis single rotor turbines (SRT) with one rotor and
nacelle placed on top of a tower. The future
challenges in extending the conventional
SRT concept to achieve higher ratings are considerable. The weight increases by
the cube of the rotor radius while the power increases with the square - this
means that material cost increases faster than power gained. An alternative to
SRT is a multi-rotor turbine (MRT) i.e. one with more rotors on the same
support structure (tower).
As a results quadrupling the power output
of a SRT can be achieved with an eightfold increase in cost whereas a 4 rotor
MRT only would quadruple the rotor cost yielding the same power increase.
However, for a MRT the support structure cost increases and the challenge is to
design load relieving control which can reduce the vibrations of the support
structure with little impact on produced power.
Based on the benchmark defined in
 create a control strategy and demonstrate that it can decrease support
structure loads (vibrations) of a multi-rotor turbine with little to no impact
on produced power. The solution should be based on standard available sensors
and coordination between the individual nacelles. It is encouraged to test out
state of the art control technologies
