Abstract: A wind energy power plant optical vibration sensor is described, using two light sources 15, 16 that emit light at different respective frequencies. The light from the first light source falls on a surface 44 of the wind energy power plant at a detection site. Movements in the surface result in changes to the phase of the light reflected back from the surface which can be detected by mixing the first light with the light emitted from the second light source. The difference in frequencies between the two light sources results in a beating of the resulting interference signal, whereas movements in the sensor surface result in changes in the phase timing and frequency of the beats.

Abstract: The present subject matter is directed to a method for estimating rotor blade loads, e.g. a blade root resultant moment, of a wind turbine. In one embodiment, the method includes measuring, via one or more sensors, a plurality of operating parameters of the wind turbine. Another step includes estimating out-of-plane and in-plane forces acting on the rotor blade based at least partially on the plurality of operating parameters. Further, the method includes determining an application point for the out-of-plane and in-plane forces along a span of the rotor blade. A further step includes estimating out-of-plane and in-plane moments of the rotor blade based at least partially on the out-of-plane and in-plane forces and the respective application points. Thus, the method includes calculating the load acting on the rotor blade based at least partially on the out-of-plane and in-plane moments.
