1. A method for detecting a fault mode of a first sensor, the method comprising:
comparing, with sensor circuitry, data output by the first sensor with reference data indicating what is expected to be output by the first sensor to produce a first comparison result, wherein the reference data includes at least one of: pre-determined data output of the first sensor during a controlled environment, and model data output from a model, wherein the model includes at least one relationship determining the model data output as a function of observed operating conditions and knowledge of properties of the first sensor; comparing, with the sensor circuitry, the data output by the first sensor with a second data output by a second sensor to produce a second comparison result; determining, with the sensor circuitry, whether the first sensor has entered a fault mode based at least in part on the first and the second comparison results; and upon the sensor circuitry determining that the first sensor has entered the fault mode, the sensor circuitry issues an indication of the fault mode to a controller of a wind turbine generator that configures the controller to issue pitch commands to adjust a blade pitch of the wind turbine generator, wherein the pitch commands are based on the controller performing at least one of: ignoring an output of the first sensor and reducing a reliance on the first sensor. |
