ABSTRACT:
A system to acoustically monitor at least one wind power installation, wherein the wind power installation includes a plurality of components including at least rotor blades. The system may comprise a remote monitoring center and a first wind power installation. The first wind power installation includes a sound pick-up device to detect an operating acoustic spectrum generated by at least one of the components of the first wind power installation during operation thereof, and circuitry to detect when a deviation between the operating acoustic spectrum of the first wind power installation and a reference spectrum exceeds a threshold. The system, in one aspect, may further include communications circuitry to communicate a fault message to the remote monitoring center when the deviation exceeds a threshold. The system may also include a remote monitoring center to monitor the operation of the first wind power installation.
