It is described a measurement arrangement for measuring a deflection of a blade (130) of a rotor (115) of a wind turbine (100). The measurement arrangement (150) comprises (a) a magnetostrictive sensor, which comprises a first sensor part (260) and a second sensor part (270), (b) a first support structure (265), which is adapted to be mounted to a first portion (220a) of the rotor (115), wherein the first sensor part (270) is mounted to the first support structure (265), and (c) a second support structure (275), which is adapted to be mounted to a second portion (232a) of the rotor (115), wherein the second sensor part (270) is mounted to the second support structure (275) and wherein at least one of the first portion (220a) and the second portion (232a) is a portion of the blade (130). The magnetostrictive sensor is capable of measuring the relative spatial position between the first sensor part (260) and the second sensor part (270). It is further described a corresponding method for measuring a blade deflection. Furthermore, it is described a wind turbine rotor (115) and a wind turbine (100) which comprise the described blade deflection measurement arrangement (150). |
