Abstract

(Hauptanspruch) Radaranlage geringer Leistung im Bereich eines Windparks, dadurch gekennzeichnet, dass die Anlage Vögel im Erfassungsbereich erkennt und diese Information dem Betriebsführungssystem der Windenergieanlagen zur Verfügung stellt.(Main claim) radar low power in the field of a wind farm, characterized in that the system detects birds in the detection area and this information provides the operational management system of the wind turbines.

Description

Windparks im Bereich von Vogelzuglinien oder in der Nähe stark genutzer Vogelrast- oder Brutplätze stellen eine Gefahr für durchziehende Vögel dar. Insbesondere die drehenden Rotoren führen dazu, dass Tiere mit dem Rotor kollidieren und getötet werden. Dies ist insbesondere bei im Schwarm ziehenden Vögeln zu berücksichtigen, da Vögel in Formation in Ihrer Möglichkeit zum Ausweichen eingeschränkt sind.Wind farms in the area of bird migration lines or in the vicinity of heavily used bird rest or nesting sites pose a risk to migrating birds. In particular, the rotating rotors cause animals to collide with the rotor and be killed. This is particularly important for birds migrating in the flock, as birds in formation are limited in their ability to dodge.

Es besteht ein technisches Problem darin, Vögel im Bereich eines Windparks zu erkennen, um notwendige Maßnahmen im Bereich der Betriebsführung der Windenergieanlagen vorzunehmen.There is a technical problem in detecting birds in the area of a wind farm in order to take necessary measures in the field of operation of the wind turbines.

Dieses Problem wird gelöst, indem eine Radaranlage geringer Leistung den Luftraum des Windparks erfasst und durch entsprechende Signalverarbeitung der Radarmessung die Anzahl und Größe sowie mögliche Formationen von Vögeln im Erfassungsbereich bestimmt.This problem is solved by a low-power radar system detects the airspace of the wind farm and determines the number and size and possible formations of birds in the detection area by appropriate signal processing of the radar measurement.

Durch eine derartige Anlage wäre es zum Beispiel möglich, bei Erkennung eines tief fliegenden Vogelschwarmes die Rotoren im Windpark stoppen. Nach Passage der Vögel könnten die Rotoren wieder gestartet werden.By such a system, it would be possible, for example, to stop the rotors in the wind farm when detecting a low-flying flock of birds. After passage of the birds, the rotors could be restarted.

Der Vorteil einer derartigen Einrichtung liegt im Schutz der Vögel vor den Gefahren durch Windenergieanlagen, ohne dass durch andere geeignete Maßnahmen, wie z. B. Verscheuchungsanlagen, auf das natürliche Verhalten der Vögel eingewirkt wird.The advantage of such a device is the protection of birds from the dangers of wind turbines, without being affected by other appropriate measures such. As scavenging plants, the natural behavior of birds is acted upon.
