Abstract

The operational reliability of power generation systems should be maintained by carrying out periodic overhaul.This paper aims to determine changes in the performance of gas turbine generator before and after overhaul using first law thermodynamic concept. Performance analysis were conducted using operating data collecte from the power plants at different load to determine the compressor efficiency, turbine efficiency, thermal effi- ciency, fuel consumption and heat rate. The highest increase after the overhaul in compressor efficiency was 1.36%, turbine efficiency 0.019% and thermal efficiency 0.805%. The largest fuel savings were 0.20 kg/s or equivalent to 17,280 kg/day natural gas. Keywords: Brayton, Cycle, Gas Turbine, Performance, Thermodynamic.
