摘要： A system and method control condensate formation within headers of a heat recovery steam generator (HRSG) in a power generation facility. The system includes measurement devices to measure first parameters including pressure at respective first locations within the power generation facility. A model estimates second parameters at second locations within the power generation facility. A prediction model outputs a prediction of time of condensate formation on each of the headers based on the first parameters and the second parameters, and a controller controls the condensate formation based on the prediction.

摘要： Systems and methods for analyzing power plant data include accessing data for one or more monitored parameters, generating a continuous time-series profile model (e.g., by generalized additive model and/or principal curves techniques) of selected parameters during instances of at least one given type of power plant operation, and conducting shape analysis by comparing the continuous time-series profile model of selected monitored parameters to an entitlement curve representing ideal performance for the at least one given type of power plant operation. Data associated with the profile modeling and shape analysis techniques may be provided as electronic output to a user. Additional steps or features may involve determining a capability index for selected monitored parameters, clustering together identified groups of profile models having similar profiles, monitoring and/or optimizing parameters to identify and improve power plant performance.

摘要： Embodiments of the invention include an inspection system to inspect internal components of a compressor of a gas turbine engine. The inspection system includes an image recording assembly having one or more image recording devices, light sources, storage devices, and power supplies. The image recording assembly may be inserted into a compressor without removal of the compressor housing or disassembly of the compressor. The image recording assembly may be removably coupled to a rotary component of the compressor, e.g., a rotor blade, and used to record images of stationary components, e.g., stator vanes, of the compressor. The images may be inspected to identify wear and/or defects in the stationary components, e.g., stator vanes
