Effect of ambient temperature on performance of gas turbine engine

Abstract

Health monitoring data, namely power output and exhaust gastemperature are used for performance analysis of an industrialgas turbine engine. Apart from ambient temperature,influences of fuel consumptions and compressor fouling onthe engine performance are also considered in the work. Amodel-free data analytics approach is used to study the effectsof individual governing factors. A performance index (ratioof power generation to fuel consumption) is proposed as themetrics for monitoring the engine performance. The step-bystepanalysis suggests that the engine performance shows twoopposing trends with the ambient temperature. Fouling is alsoclearly shown to reduce the engine performance using theproposed indices.
