  • Publication number: 20130309088
    Abstract: A method for protecting wind turbine equipment in a fire event is disclosed. The method may include providing a wind turbine and a fire detection and suppression system capable of detecting a fire within the wind turbine, the fire detection and suppression system further capable of generating and communicating a fire signal to the wind turbine, the fire signal including a location of the fire within the wind turbine and taking one or more actions by the wind turbine in response to the fire signal, the one or more actions dependent upon the location of the fire within the wind turbine.

  • Publication number: 20130307270
    Abstract: A fire detection and suppression system for a wind turbine is disclosed. The fire detection and suppression system may be capable of independent operation without input from the wind turbine. The fire detection and suppression system may further be capable of generating and communicating a fire signal to the wind turbine for conveying a fire within the wind turbine. The wind turbine may take actions to shut down and put itself in a protected condition depending upon the location of the detected fire.

  • Publication number: 20120242085
    Abstract: A yaw-drive system for a wind turbine housed in a movable-in-yaw nacelle affixed atop a tower on a roller bearing. A round-look high-flux core material forms the stator of a circular linear yaw motor. The stator is affixed to the tower and is stationary. A plurality of magnets is affixed to the nacelle in proximity with the core material, such that as the stator is excited in quadrature the nacelle rotates on the roller bearings about a yaw pivot.
