Abstract

A wind power plant, including a generator driven by a rotor in order to generate electrical power and a controller that includes a pitch module for adjusting a pitch angle of blades of the rotor. The controller has an input for a required power reserve and determines a target pitch angle depending on an operating point of the wind power plant. A secondary pitch controller is also provided, which includes a detector for available power and a dynamic offset module. Input signals for the available reserve power determined by the detector, the required reserve power and the generated electrical power are applied to the dynamic offset module, which is designed to determine a value for a pitch angle offset. An activation element varies the target pitch angle by the pitch angle offset.
