Measuring device for detecting load of rotor blade of rotor of wind turbine, has sensor obtaining rotational speed about longitudinal axis of rotor blade and transmitting unit transmitting measurement signal to control unit

摘要

The device has a sensor (114) and a transmitting unit i.e. wireless optical carrier, where the sensor is arranged in a rotor blade (108). The sensor obtains rotational speed about a longitudinal axis (112) of the rotor blade to obtain a measurement signal. The transmitting unit transmits the measurement signal to a control unit (116). A recognizing device recognizes transit of the rotor blade before a tower (102) of a wind-power plant (100). The sensor is designed to obtain rotational speed and/or bending in an impact direction. Independent claims are also included for the following: (1) a control system (2) a method for detecting a load of a rotor blade of a rotor of a wind turbine.
