The activities have been broadly divided into two
different approaches: modelling of the wind turbine's
aerodynamical, mechanical and electrical behaviour and,
on the other hand, development, laboratory testing and
modelling of technologies of active structural parts to
be used in the turbines.
An adaptive wing profile was designed, manufactured and
tested. Novel tools for designing, modelling, and
manufacturing of composites with embedded SMA actuators
were developed and demonstrated. Patentability evaluation
of the developed composite technology is ongoing.
Several stiffness control concepts utilizing actuator
property of Shape Memory Alloys (SMA) have been
developed. A 3-5 fold on/off type stiffness increase has
been demonstrated with these devices. One patent
application on studied concepts has been deposited.
Several numerical studies on an offshore wind turbine
structure are made in order to study application
potentiality of adaptive components.
A multidisciplinary-modelling environment has been
developed and is used in power system dynamic studies of
wind farms. Active duration and load control algorithms
have been included and demonstrated in the developed
The research activities of five research groups in three
institutes have been combined. The groups have
established networks with several researchers with
different expertise in Europe and USA. Some results have
been taken into use in other projects with industrial
involvement. Many results have much wider applicability
than just wind energy.
