Abstract

A management system for a wind energy plant including at least one control unit, and a method using the management system are disclosed. The management system is used to coordinate component modules of the wind energy plant with vibration damping modules and/or load reduction modules, wherein a sensor system supplies data of the operating states of the component modules for a system analysis. For this purpose, reactive vibrations and/or predictive forecasts of vibrations of the wind energy plant, and predictive disturbance variables are registered, and the vibration damping modules and/or load reduction modules in the control unit are activated, wherein an actuator carries out damping measures and/or load reduction measures on the component modules in accordance with the vibration damping modules and/or load reduction modules of the control unit.

First claim

The invention claimed is:

1. A method using a management system for a wind energy installation comprising:
detecting data relating to at least one of operating states of components of the wind energy installation with respect to reactive oscillations and/or loads and/or predictive prognosis of oscillations and/or loads of and/or on the wind energy installation, and with respect to predictive disturbance variables;
activating actuators of a plurality of oscillation damping modules for damping and/or load reduction of acute or predicted oscillation states of a plurality of component modules and/or of subsystems of the wind energy installation, the plurality of component modules and/or of subsystems of the wind energy installation including at least a rotor, a drive train, and a generator, each of the component modules having at least one oscillation damper module associated therewith;
generating electrical energy with matching to the frequency, current and voltage demand of the downstream grid;
actuating the oscillation damping modules such that the damping measures performed by one of the subsystems are distributed to another of the subsystems when the one of the subsystems fails; and
diagnosing damage to a subsystem by changes in the oscillation behavior of the subsystem, and deducing a remaining life of the wind energy installation with the aid of statistical methods based on the measurement results from the sensor system.
