Abstract: A method for detecting actual slip in a coupling of a rotary shaft, for example, in a wind turbine power system, includes monitoring, via a controller, a plurality of sensor signals relating to the coupling for faults. In response to detecting a fault in the plurality of sensor signals relating to the coupling, the method includes determining, via the controller, whether the fault is indicative of an actual slip or a no-slip event of the coupling using one or more classification parameters. When the fault is indicative of the actual slip, the method includes estimating, via the controller, a magnitude of the actual slip using the plurality of sensor signals and a time duration of the actual slip. Further, the method includes implementing, via the controller, a control action based on the magnitude of the actual slip in the coupling.

Abstract: A control system for a wind turbine configured to generate an acoustic emission during operation includes a communication device. The communication device is configured to receive at least one penalty notification identifying a penalty to be assessed based on the acoustic emission generated. The control system also includes a processor coupled to the communication device. The processor is configured to calculate an acoustic emission level to be generated by the wind turbine based on the penalty and based on at least one of a power generated by the wind turbine and an economic value attributed to the wind turbine, and adjust at least one characteristic of the wind turbine to cause the wind turbine to operate at the calculated acoustic emission level.
