Abstract

This study discusses the topic of thermal efficiency analysis in gas turbines. This study aims to determine the effect of using LNG and HSD fuel on the value of thermal efficiency. Therefore, the actual brayton cycle calculation method is used. This research is doing data processing using software, namely Microsoft Excel, Engineering Equation Solver (EES) and Cycle Tempo. Based on the results of the calculations that have been carried out, the thermal efficiency at a load of 75 MW with LNG fuel is 37.96% to 44.62% at a load of 100 MW and with HSD fuel at a load of 75 MW it is 40.61% and 45.60% at a load of 100 MW. Then in the EES simulation results with LNG fuel at a load of 75 MW it is obtained 37.51%, and 41.96% at a load of 100 MW. whereas with HSD fuel at a load of 75 MW it was obtained 41.76% and 46.15% at a load of 100 MW, and also the results of the cycle tempo simulation with LNG fuel at a load of 75 MW were 32.56% to 37.43% at a load 100MW. Then with HSD fuel at a load of 75 MW it is 34.47% to 38.14% at a load of 100 MW

Abstract

Electricity is one of the most important needs in everyday life due to technological advances. So various efforts are needed to increase electricity production, one way is to build a power plant that can produce productive electricity so that this happens, one way to determine electricity productivity is the value of cycle efficiency. If the value of the cycle efficiency is higher in a generator, then the PLTG performance will be maximized. And if the cycle efficiency value gets smaller, it can be said that the PLTG's performance is not good. Therefore, to maintain PLTG performance, it is necessary to carry out an overhaul to maintain optimal PLTG performance. In this study using cycle efficiency to determine the increase in efficiency before and after overhaul at a load of 100 MW and the causes, after analyzing the efficiency of the brayton cycle increased from 41% to 42%, the cause was a decrease in turbine efficiency from 74 to 91% and compressor efficiency from 73 to 82% after overhaul the increase affected fuel consumption so that the requirement of kcal/kwh decreased to 3196.4 kcal/ Kwh
