Abstract

La presente se refiere a un procedimiento para el reconocimiento de la presencia de hielo en una instalación de energía eólica, en especial sobre un rotor de la instalación de energía eólica, con por lo menos una pala de rotor, un medio de calentamiento para calentar la por lo menos una pala de rotor y un sensor de temperatura, caracterizado porque el sensor de temperatura para detectar una signatura de temperatura en forma de una variación de la temperatura esta configurado en por lo menos un punto de medición sobre una superficie de la pala de rotor, y porque el procedimiento abarca las siguientes etapas, a saber una prefijación de una signatura de temperatura de referencia de la pala de rotor, en donde la signatura de temperatura de referencia describe la variación de temperatura en el por lo menos un punto de medición sobre la superficie de la pala de rotor para un estado libre de hielo de la instalación de energía eólica; un calentamiento de la por lo menos una pala de rotor en el por lo menos un punto de medición sobre la superficie de la pala de rotor mediante el medio de calentamiento; una detección de la signatura de temperatura para el por lo menos un punto de medición sobre la superficie de la pala del rotor durante el calentamiento; una comparación de la signatura de temperatura detectada con la signatura de temperatura de referencia; una determinación de un resultado de evaluación en base a la comparación; y una asociación del resultado de la evaluación a un estado cubierto de hielo de la instalación de energía eólica, cuando se comprueba una desviación entre signatura de temperatura detectada y la signatura de temperatura de referencia o en caso contrario al estado libre de hielo de la instalación de energía eólica. Además, la presente se refiere a una disposición para reconocer la presencia de hielo en una instalación de energía eólica.This refers to a procedure for the recognition of the presence of ice in a wind power installation, especially on a rotor of the wind power installation, with at least one rotor blade, a heating means for heating the at least one rotor blade and a temperature sensor, characterized in that the temperature sensor for detecting a temperature signature in the form of a temperature variation is configured at least one measuring point on a surface of the blade of rotor, and because the procedure encompasses the following steps, namely a presetting of a reference temperature signature of the rotor blade, where the reference temperature signature describes the temperature variation in the at least one measuring point on the surface of the rotor blade for an ice-free state of the wind power installation; a heating of the at least one rotor blade at the at least one measuring point on the surface of the rotor blade by means of the heating means; a detection of the temperature signature for the at least one measuring point on the surface of the rotor blade during heating; a comparison of the temperature signature detected with the reference temperature signature; a determination of an evaluation result based on the comparison; and an association of the result of the evaluation to an ice-covered state of the wind power installation, when a deviation between the detected temperature signature and the reference temperature signature is checked or otherwise the ice-free state of the installation of wind power. In addition, this refers to an arrangement to recognize the presence of ice in a wind power installation.
