Title
(DE) WINDKRAFTANLAGENREGELUNG AUF BASIS VON SCHALLEMISSIONSMESSUNG DURCH DRUCKSENSOREN AN ROTORBLÄTTERN
(EN) WIND TURBINE CONTROL BASED ON NOISE EMISSION MEASUREMENT USING PRESSURE SENSORS ON ROTOR BLADES
(FR) RÉGULATION D'ÉOLIENNE SUR LA BASE DE LA MESURE D'ÉMISSIONS SONORES AU MOYEN DE CAPTEURS DE PRESSION AU NIVEAU DE PALES DE ROTOR
Abstract
(DE)
Es wird eine Messeinrichtung sowie ein Verfahren zur Bestimmung von Schallemissionen eines mehrerer Rotorblätter einer Windkraftanlage, mit mindestens einem Sensor, der dazu angepasst ist, Schwingungen an einem oder mehreren Rotorblättern zu detektieren und ein Ergebnis als Signal zur Verfügung zu stellen; wobei der mindestens eine Sensor flächenbündig zur Oberfläche der Rotorblätter angebracht ist.
(EN)
The invention relates to a measuring device and to a method for determining sound emissions of one of several rotor blades of a wind turbine, comprising at least one sensor which is designed to detect vibrations on one or more rotor blades and to provide a result as a signal; wherein the at least one sensor is mounted flush with the surface of the rotor blades.
(FR)
L'invention concerne un dispositif de mesure ainsi qu'un procédé de détermination d'émissions sonores d'une parmi plusieurs pales de rotor d'une éolienne, comprenant au moins un capteur qui est adapté à la détection de vibrations au niveau d'une ou de plusieurs pales de rotor et à la fourniture d'un résultat comme signal. L'au moins un capteur est installé à fleur de la surface des pales de rotor.
