SYSTEM AND METHOD OF CONTROL FOR A GAS TURBINE ENGINE

摘要

A system includes plurality of combustors and a distributed flow measurement system coupled to the plurality of combustors. Each combustor of the plurality of combustors includes one or more oxidant passages and one or more fuel passages. The distributed flow measurement system is configured to measure an oxidant flow rate for a respective oxidant passage of the one or more oxidant passages of the respective combustor based at least in part on an oxidant pressure drop along the respective oxidant passage, and the distributed flow measurement system is configured to measure a fuel flow rate for a respective fuel passage of the one or more fuel passages of the respective combustor based at least in part on a fuel pressure drop along the respective fuel passage.

1. A system comprising:
a first combustor, comprising:
a plurality of first oxidant passages configured to supply a first oxidant flow to the first combustor;a plurality of first fuel passages configured to supply a first fuel flow to the first combustor;a plurality of first oxidant pressure sensors, wherein each first oxidant pressure sensor of the plurality of first oxidant pressure sensors is fluidly coupled to a respective first oxidant passage of the plurality of first oxidant passages and is configured to transmit a respective first oxidant pressure signal; anda plurality of first fuel pressure sensors, wherein each first fuel pressure sensor of the plurality of first fuel pressure sensors is fluidly coupled to a respective first fuel passage of the plurality of first fuel passages and is configured to transmit a respective first fuel pressure signal; and a controller coupled to the plurality of first oxidant pressure sensors and to the plurality of first fuel pressure sensors, wherein the controller is configured to determine a first oxidant flow rate through each first oxidant passage of the plurality of first oxidant passages based at least in part on the respective first oxidant pressure signal and a first reference oxidant pressure, and the controller is configured to determine a first fuel flow rate through each first fuel passage of the plurality of first fuel passages based at least in part on the respective first fuel pressure signal and a first reference fuel pressure.
