Реферат: The invention describes a wind turbine rotor blade monitoring arrangement (1) comprising an electrodynamic exciter (10) mounted on the rotor blade (20); an excitation unit (11) configured to generate an excitation signal (110) for the electrodynamic exciter (10); a force sensor (10F) configured to measure force (100) imparted to the rotor blade (20) during operation of the electrodynamic exciter (10), which force sensor (10F) is collocated with the electrodynamic exciter (10); a vibration sensor (12) arranged on the rotor blade (20) at a distance from the electrodynamic exciter (10); and an evaluation unit (13) configured to infer a health status of the rotor blade (20) on the basis of a vibration sensor output (120) and the measured force (100). The invention further describes a method of monitoring the health status of a wind turbine rotor blade (20).
