CONTROL METHOD OF GAS-TURBINE UNIT TECHNICAL CONDITION Russian patent published in 2011 - IPC G01M15/14 

FIELD: engines and pumps.

SUBSTANCE: invention can be used in electronic systems (ACS) of automatic control of gas-turbine units (GTU) of gas-compressor plant (GCP) and gas turbine electric power stations (GTEPS). Additionally in the process of GTU operation there recorded is a quantity of GTU start-ups and emergency starts. Also the temperature of gases after GTU turbine is measured and the number of its sudden changes is recorded, mark and quality of fuel supplied into GTU combustion chamber (CC) is recorded, the quantity of water injections to GTU input is recorded, GTU operating time in the mode of basic load and peak load is fixed. The following parameters are defined by calculation-experiment approach: influence coefficient of start-ups and emergency starts, sudden changes of gas temperature after GTU turbine, water injections to GTU input, quality of fuel supplied into GTU combustion chamber, GTU load mode during its operation on GTU working life speed. The equivalent operating time of GTU is calculated, then, it is compared with total operating time. If equivalent operating time exceeds total operating time, it is used for defining the terms of GTU scheduled works and overhaul.

EFFECT: increase of GTU technical condition evaluation quality and improvement of GTU, GCP and GTEPS operating reliability.
