Abstract :
Demand for electricity needs is increasing, making the plants must be reliable to serve electricity supply to the public. So that makes the engines vulnerable to maintenance. In the PLTG there are 3 types of maintenance levels based on operating hours namely CI, HGPI, MI. To determine the effect of HGPI on the efficiency of a gas turbine, then use the efficiency calculation method based on the data before and after the ideal brayton cycle with the method and actual brayton cycle. Influence before and after HGPI is seen from changes in thermal efficiency of gas turbines. After conducting HGPI, there was an increase in efficiency of Gas Turbine, namely in the Actual condition with a load of 100 MW from 29.19% to 31.90%, increasing by 2.71%.
