Analysis and diagnostics of GTE 6/6,3 MC gas turbine units
Practical approaches to carrying out thermal gas-dynamic diagnostics of gas turbine units (GTU) are studied in the article. The author analyzed the main approaches to diagnosing of gas turbine units, modern theoretical-methodological and applied developments in this field conducted by Russian researchers. The integral methods for assessing the technical state of GTU, the differential and partially differential methods of aggregate-by-aggregate diagnostics, the use of special software for parametric diagnostics, the use of nondestructive testing methods to determine the hidden internal defects of assemblies and aggregates. The creation and implementation of GTU parametric passport is substantiated, which in future will help the operating enterprises to evaluate the quality of repairs and to provide an effective assessment of GTU current state. The working modes of GTE 6/6.3 MC were studied. A practical example is used to consider the application of thermal gas-dynamic diagnostics in operational conditions. It required the use of a limited list of nominal and operating parameters of the drive flow-through part. Diagnostic functions were performed by the automatic control system (ACS) being a part of GTE 6/6.3 MC unit.
