  • Patent number: 9577421
    Abstract: The present subject matter is directed to a system and method for operating a wind turbine connected to a power grid. The method includes receiving, via a controller, one or more current feedback signals from one or more electric current sensors of the wind turbine. Another step includes determining, via the controller, if a ground fault is occurring in the wind turbine based on the current feedback signals. In response to detecting a ground fault, the method includes tripping one or more electrical components of the wind turbine and electrically de-coupling the wind turbine from the power grid.

  • Patent number: 9574965
    Abstract: A monitoring system and method monitor changes in clearance distances between a sensor and a rotating component of a machine. Imbalance and/or wear in the machine is identified based on the changes in the clearance distances. The system and method optionally both measure the clearance distances and a rotating speed of the rotating component of the machine with the same sensor. In order to identify imbalance in the machine, a spectral energy of the machine can be calculated based on the changes in the clearance distances, and the imbalance in the machine can be identified based on the spectral energy. The system and method can determine a trigger speed of the machine that is associated with the wear in the machine based on the changes in the clearance distance. A remaining useful life of the machine can be estimated based on changes in the trigger speed.
