METHOD FOR OPERATION OF A GAS TURBINE INSTALLATION Russian patent published in 2022 - IPC G01M15/14 

FIELD: power industry.

SUBSTANCE: invention relates to the field of operation of gas turbine installations, namely, to the diagnosis of the temperature condition of parts for making decisions on their maintenance and further operation. The method for operation of the gas turbine installation includes diagnostics of the temperature condition of the parts. The oil temperature at the drain is measured from each support of the rotors of a gas turbine installation in a constant mode according to the rotation frequencies of the rotors based on a time of at least 2 minutes preceding the current measurement, the average value of the oil temperature at the drain is calculated and compared with the current value at the same rotation frequencies. If the current oil temperature at the drain deviates by more than 2°C, a signal is generated about a change in the technical condition of the parts in a particular rotor support. When the current oil temperature decreases, a signal is generated at the drain about the destruction of the oil supply collector to the bearing in the support. When the oil temperature rises on the drain, a signal is generated about the destruction of the bearing in the support.

EFFECT: method makes it possible to determine the parts in a specific engine support in which there is a change in the technical condition at the stage of the permissible operating time without destroying the engine parts, which increases the operational efficiency of the gas turbine engine.
