METHOD AND DEVICE TO GENERATE SIGNAL OF SETTING POINT Russian patent published in 2015 - IPC F02C9/26 

FIELD: power engineering.

SUBSTANCE: invention relates to power engineering. The method to generate a fuel supply setting point signal sent by a valve of slide type in a metering device into a fuel injection system for fuel injection into a turbine engine combustion chamber, besides, the position of the slide valve depends on the setting point signal. The method includes stages, where they receive the first signal, which represents the result of measurement of fuel flow rate by a flow meter as fuel is injected into the combustion chamber; the second signal is assessed on the basis of results of measurement of the slide valve position; the third signal is assessed by applying the digital model of the flow meter to the second signal, and the setting point signal is generated by summing the signal of compensation with the first signal, besides, the compensation signal is produced by subtraction of the third signal from the second signal. Also the method is provided for signal supply, a device of signal generation, a signal supply system and a gas turbine.

EFFECT: invention makes it possible to improve accuracy of fuel flow measurement.
