PROCEDURE FOR CONTROL OVER TECHNICAL CONDITION OF GAS-TURBINE INSTALLATION Russian patent published in 2011 - IPC G01M15/14 

FIELD: machine building.

SUBSTANCE: during operation of gas-turbine installation (GTI) there is additionally measured temperature of oil at input to engine. Further, temperature of oil at input to engine is compared with four preliminary specified values determined with a calculation -experiment method and specified during the GTI operation. In case temperature of oil at input to the engine is lower, than the first preliminary specified value during preliminary specified period determined by the calculation-experiment method, there is formed a signal "minimal temperature of oil at input to the engine" and there are turned on heating elements (HE) in an oil tank of the GTI. If temperature of oil at input to the engine is higher, than the second preliminary specified value during preliminary specified period determined by the calculation-experiment method, there are turned on fans of an oil cooler unit (OCU). When temperature of oil at input to the engine is higher, than preliminary specified value during preliminary specified period determined by the calculation-experiment method, there is formed the signal "Maximal temperature of oil at input into the engine". There is measured temperature of Babbitt-metal of bearing inserts of the GTI turbine and it is compared to the fifth preliminary specified value determined by the calculation-experiment method and specified during operation of the GTI. If temperature of the Babbitt-metal of bearing inserts of the GTI turbine is lower or equal to the fifth preliminary specified value, then with decrease of fuel consumption in a combustion chamber (CC) of the GTI, mode of the GTI operation is gradually lowered till temperature of oil at input to the engine drops below the third preliminary specified value. If temperature of Babbitt of bearing inserts of the GTI turbine is higher, than the fifth preliminary specified value, then there is formed a signal.

EFFECT: improved procedure.
