Analyzing Gas Turbine Performance Through Simulation and Performance Tests: Case Study of Gas Turbine Units in Jambi, Indonesia

Summary/Abstract: The purpose of this research is to analyse and compare the performance of units 1 and 2 of the gas turbine (GT) power plant based on simulation results and tests in terms of performance, to identify factors causing a decrease in gas turbine performance, and provide recommendations to improve gas turbine. The study was carried out in GT units in Jambi, Indonesia. In this location, there are two identical GT units with a capacity of 34.25 megawatts electric (MWe). The analysis was carried out using three methods, namely performance test, inspection of the measurement instruments, and simulation of the thermodynamic performance using GT-Pro software. To improve the performance of the gas turbine, it is necessary to clean the compressor blades, online compressor washing or manual deposit cleaning on the compressor blades during the overhaul, calibrate manometers, and inspect the piping line of the differential pressure of Air Inlet Filter, and also carry out inspection and calibration of the exhaust gas thermocouple on numbers 1, 2, 5, and 8 of GT Unit 2. This research not only presents practical recommendations for improving the performance of GT in Jambi, Indonesia, but also contributes to the broader field of gas turbine technology. The findings and recommendations can be applied in the power generation industry worldwide, helping to enhance the efficiency and reliability gas turbine power plants.
