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.
Claims13
A wind turbine comprising:
- a generator, which is driven by a rotor, for producing electrical power,
- a controller which has a pitch module for adjusting a pitch angle of blades of the rotor, the controller determining a nominal pitch angle as a function of an operating point of the wind turbine, the controller further having an input for a required power reserve,
- a secondary pitch regulator comprising:
- a detector configured to determine an available power, the available power being an electrical power that is theoretically obtainable in prevailing wind conditions via the rotor and the generator,
- a dynamic offset module, with input signals for the available power, the required power reserve, and the electrical power produced, wherein the dynamic offset module is configured to determine a value for a pitch angle offset, and
- an activation element configured to vary the nominal pitch angle by the pitch angle offset.
