    摘要： A method for detecting ice on a wind turbine having a rotor and one or more rotor blades each having blade roots includes monitoring meteorological conditions relating to icing conditions and monitoring one or more physical characteristics of the wind turbine in operation that vary in accordance with at least one of the mass of the one or more rotor blades or a mass imbalance between the rotor blades. The method also includes using the one or more monitored physical characteristics to determine whether a blade mass anomaly exists, determining whether the monitored meteorological conditions are consistent with blade icing; and signaling an icing-related blade mass anomaly when a blade mass anomaly is determined to exist and the monitored meteorological conditions are determined to be consistent with icing.

    摘要： A wind turbine condition monitoring system includes a light source configured to produce an emitted light beam and a plurality of optical sensors configured to be positioned on a wind turbine to receive the emitted light beam from the light source. The optical sensors are configured to generate one or more product light beams from the emitted light beam. A detector is positioned to receive the product light beams generated from the optical sensors and is configured to measure intensity values of the product light beams for the optical sensors. A computing device is coupled to the detector and includes a processor and a memory coupled to the processor. The processor executes programmed instructions stored in the memory to determine, based on the intensity values for the product light beams for the optical sensors, at least a displacement value, a current value, and a voltage value for the wind turbine.
