Directive GL2010 presents a challenge, particularly for state-of-the-art
electromechanical AC pitch systems. Unlike DC pitch systems, they do
not have a redundant activation channel for emergency movement into
the feather position. The directive only provides indications, leaving
engineers to interpret what safety functions will be needed and how to
ensure their performance level complies with EN ISO 13849.
During our workshop, we will discuss the safety requirements of
GL2010, including their implications for pitch systems.

The drivetrain of many wind turbines installed has been based on the
concept of collecting standard components such as a gearbox
and a double fed induction generator (DFIG) connected directly to the
grid and with a power converter controlling the rotor.
This concept is however being challenged by the need for higher reliability, strict grid requirements and increasing power ranges especially for the future offshore turbines. Thus there is a trend towards introducing direct drive generators with a full power converter both tailored to a specific turbine. This workshop will discuss the choice of active materials for the present and future direct drive generators, the implications on performance and possible supply chain issues.

The reliability of electronic control systems are of high importance as failures may cause significant economic loss and unplanned maintenance of the systems is necessary. In respect to the long expected lifecycle of wind turbines, a high availability control system architecture helps to avoid unplanned repairs. It can help to optimize the cost of operation and is in fact one important aspect when it comes to competitive advantages in energy production.
Electronic platforms which offer scalable fault tolerance, safety and
high availability can assure that control systems are reliable and designed
for more efficient operation.
