Abstract

A method (500) of detecting a fault mode of a sensor is provided. The sensor may be, for example, a bending moment sensor (142) and may sense a bending moment of a blade (140) on a wind turbine generator (WTG) (100). The method (500) includes comparing (520, 530) data output by a first sensor (142) with reference data indicating what is expected to be output by the first sensor (142) to produce a first comparison result and comparing (550) data output by the first sensor (142) with data output by a second sensor to produce a second comparison result. A determination of whether the first sensor (142) has entered a fault mode is made (560) based at least in part on the first and second comparison results.
