Abstract
The importance of continuing production in high winds to
production is increasing from the grid companies perspective.
pitch regulated variable speed 2MW turbine to produce power
cut-out wind speed of 25m/s without substantially increasing
load cases for wind speeds from 4m/s to 50m/s for a IEC61400-
performed. Statistics in terms of mean value and standard
calculations are performed to estimate the impact over the
alternative power-speed control to the traditional approach is
and power set-points are gradually reduced, for increasing
speed of 25m/s. With the above suggested control strategy, it
the tower vibration loads, both fore-aft and side-to-side, are still
load reduction controllers are investigated. First, a fore-aft tower
pitch based on measurements of the fore-aft tower top acceleration
side tower damper algorithm using an additional torque demand,
side-to-side tower top acceleration, makes significant load reductions
tower loading possible. The load reduction controllers manage
loading, if not to the original loads with shutdown at 25m/s.
