Abstract

A wind turbine power plant comprises a plurality of wind turbines each having a rated output and under the control of a power plant controller. The power plant also has a rated output which may be over rated in response to one or more of electricity pricing data power plant age and operator demand. The power plant controller can send over rating demand signals to individual turbines. The controllers at the turbines include a fatigue life usage estimator which estimates a measure of the fatigue life consumed by key components of the turbine. If this measure exceeds a target value for any component over rating is prevented at that turbine.
