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.

Method and apparatus for selective data control

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.

Method and apparatus for remotely monitoring gas turbine combustion dynamics

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.

Method and system for determining lean blow out condition for gas turbine combustion cans

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.

Method and apparatus to detect onset of combustor hardware damage

A system for compressing a set of data points is provided. The system includes a critical aperture compression module that is configured to discard one or more data points from the set of data points. The discarded one or more data points fall within a tolerance band surrounding a straight line that represents a trend of the discarded one or more data points. A remainder of the set of data points represents a compressed set of data points.

Critical aperture convergence filtering and systems and methods thereof

A system and method for tuning a turbine comprises a turbine controller coupled to the turbine, a first computer system coupled to the turbine controller and located locally to the turbine, and a second computer system for exchanging data with the first computer system. The second computer system is located remotely from the turbine and exchanges data with the first computer system via a network connection such as the internet, an intranet or a virtual private network (VPN). Data relating to a characteristic such as turbine combustion dynamics and/or emissions is transmitted by the first computer system to the second computer system. The second computer system transmits control data over the network connection to the first computer to tune the turbine.

Remote tuning for gas turbines

An X-ray inspection system for manually or automatically performing digital fluoroscopy inspections and/or computed tomography inspections by X-ray examination of manufactured parts incorporates a computer system which automatically analyzes the inspected parts for flaws. The system includes apparatus for automatically positioning the parts in an X-ray machine for obtaining fluoroscopy and tomography views of the part and for acquiring data from the inspections at production rates. The system automatically identifies the location of rejectable flaws in the parts during the fluoroscopy scanning and subsequently identifies those locations for obtaining tomography scans, if the identified flaw location is questionable. The system can automatically reject parts containing flaws identified during the fluoroscopy inspections. This system operates in a real-time environment by providing analysis of one part while a subsequent part is being subjected to X-ray examination. The data obtained during each examination is archived and stored for tracking the part in further manufacturing processes.
