Abstract: A method of selectively controlling communication between a supervisory processor and a subscriber is provided. The method includes receiving a stream of data at the supervisory processor, controlling transmission of the stream of data from the supervisory processor to the subscriber based on an associated supervisory processor configuration, receiving an enabling configuration at the supervisory processor which alters the supervisory processor configuration, and transmitting at least a portion of the controlled stream of data from the supervisory processor to the subscriber based on the supervisory processor configuration.

Abstract: A method and system of testing an overspeed protection system of a turbomachine. The method and system may include providing an overspeed protection system on a turbomachine that may have a single or multiple shafts; determining whether the speed the shaft or shaft(s) exceeds a shutdown value; changing an overspeed trip value of the turbomachine; and determining whether the overspeed protection system would operate to trip the turbomachine.

Abstract: Methods and systems for communicating information between a narrowband circuit and a broadband circuit for conserving bandwidth while monitoring gas turbine combustion dynamics are provided. The method includes receiving a stream of data through the narrowband circuit, splitting the stream of data into a plurality of data packets, and transmitting each of the data packets to a predetermined list of sockets through the broadband circuit. The system includes a narrowband network segment communicatively coupled to a broadband network segment, and a data network split/relay device communicatively coupled to the broadband network segment programmed to receive a stream of data from a server communicatively coupled to the narrowband segment.

Abstract: A method and system of testing an overspeed protection system of a turbomachine may include providing an overspeed protection system on a turbomachine having at least one shaft. The method may: determine whether a permissive or permissive(s) is satisfied; initiate an overspeed test; automatically adjusting the speed of a shaft; determining if the speed exceeds an overspeed trip value; and automatically disabling the automatic adjustment of the speed after the test is complete.

Abstract: A method for determining a lean blow out condition for a combustor. In an exemplary embodiment, the method includes determining acoustical frequency data for the combustor, determining a combustor flame temperature based on the acoustical frequency data, determining an existing fuel/air ratio in the combustor based on the combustor flame temperature, and comparing the existing fuel/ratio to a lean blow out fuel/air ratio. A lean blow out condition for the combustor is indicated when the existing fuel/air ratio is about equal to the lean blow out fuel/air ratio.

Abstract: Methods and systems for modifying a turbine control system may be provided for. A method may include replacing at least one legacy main controller processor communicating in a first communication protocol with a current main control processor communicating in a second communication protocol, retaining at least one legacy IO processor in communication with at least one turbine monitoring device communicating in the first communication protocol, and providing at least one converter in communication with the current main controller processor or processors and in communication with the legacy IO processor or processors. The converter may translate communications between the current main controller processor or processors and the legacy IO processor or processors by translating between the second communication protocol and the first communication protocol.

Abstract: A method for determining when a combustor is experiencing hardware damage includes sensing acoustic vibrations of a plurality of combustor cans, determining a center frequency for each acoustic tone of the sensed acoustic vibrations within a predetermined frequency range, and indicating an alarm when a center frequency of one or more of the combustor cans changes in a different manner compared to a representative center frequency of the plurality of combustor cans.
