To develop a model for the predictive analysis of structural members in a gas turbine unit and to demonstrate the possibilities for detecting defects and process failures during the GTU operation, prior to their occurrence.
Apply F5 PMM as a system for the diagnostics and forecast of the technical condition of equipment.
Input data: certificate characteristics, list of controlled parameters, description of the circuit diagram, piping and purging diagrams (with ICA specifications), telemetry data for 1 year of GTU operation.
Sequence of actions
- the historical data of the gas turbine operation has been analyzed
- the relevant parameters characterizing the GTU structural members are determined
- predictive models for the GTU structural members are developed using a set of mathematical algorithms
- time intervals with nominally normal GTU operation modes, which presumably had no defects, were determined to train models
