Abstract (en)

[origin: WO2019012083A1] The invention relates to an assembly for monitoring and/or controlling a wind turbine. The assembly for monitoring and/or controlling a wind turbine comprises: an arrangement of two strain sensors, in particular three strain sensors, which detects blade bending moments of a rotor blade of a wind turbine in at least two different spatial directions; a first fibre optic vibration sensor for detecting vibrations of the rotor blade in a first spatial direction; and at least one second fibre optic vibration sensor for detecting vibrations of the rotor in a second spatial direction, which differs from the first spatial direction.
