GAS TURBINE OPERATION ANALYSIS METHOD Russian patent published in 2013 - IPC G05B13/02 

FIELD: machine building.

SUBSTANCE: at least one dynamic pressure signal is measured by means of at least one pressure sensor in or on the turbine compressor, as well as one or more operating parameters of the turbine are measured by means of one or more other sensors under normal operating conditions of the turbine, and/or dynamic pressure signal, as well as one or more other operating parameters, which have been measured under normal operating conditions of the turbine, are read out; at that, dynamic pressure signal is subject to frequency analysis, by means of which one or more parameters of frequency spectrum of pressure signal are determined. Based on one or more measured operating parameters and one or more parameters of frequency spectrum of pressure signal, one or more neutron networks are trained, which have one or more measured operating parameters and one or more parameters of frequency spectrum of pressure signal as input values, and have at least one diagnostics parameter as the output value, which represents the measure of probability for availability of normal operating conditions of the turbine depending on input values.

EFFECT: improving diagnostics accuracy of wear and damages to the turbine.
