  • Turbine bucket including an integral rotation controlling feature
    Patent number: 9057278
    Abstract: A turbine bucket including an integral rotation controlling feature is disclosed. In one embodiment, a turbine bucket includes: a blade section having an inner radial end and an outer radial end; an integral cover section connected to the outer radial end of the blade section; and a base section for engaging a rotor body, the base section connected to the inner radial end, wherein the base section includes: a central body; a set of tangs extending axially from the central body; a set of flanges radially inboard of the set of tangs and extending axially from the central body; and an integral rotation controlling feature extending from the central body, wherein the rotation controlling feature engages a radial opening in the rotor body. The integral rotation controlling feature is sized to limit rotation of the base section, when the turbine bucket is engaged with a rotor body.

  • Method for determining limit exceedance
    Patent number: 7470103
    Abstract: A method and system for determining a limit exceedance of an operating parameter in a steam turbine system. Measurement data associated with the operating parameter is received, and a limit exceedance is determined when the rate of change in the received data over a predefined period of time exceeds a predefined limit. A control action is taken when a limit exceedance has been determined.
