Method for controlling the revolutions of a wind energy installation comprises calculating the relative number of revolutions using a transmitting arrangement having a transmitting section and a sensor arrangement with sensors which respond on the transmitting section between the transmitting arrangement and the sensor arrangement, measuring the time for the transmitting section between the two sensors, and calculating the number of revolutions. An independent claim is also included for an arrangement for controlling the revolutions of a wind energy installation. Preferred Features: The transmitting section is fixed to a rotating shaft (20) of the wind energy installation and the sensor arrangement is arranged in a stationary manner. |
