Abstract :
PLTDG Pesanggaran is one of the power plants owned by PT. Indonesia Power uses 2
fuels, namely gas and diesel. Power plants that operate continuously require good
performance to be reliable, safe, and have good economic value in absorbing fuel. One
of the indicators that are often a picture of engine performance is the use of specific fuels
(SFC and SGC) and heat rate. Monitoring of engine performance can be done periodically
by performing a performance test. This study analyzes the effect of load variations on
fuel consumption for units 3 and 7 of PLTDG at PT.Indonesia Power Pesanggaran. The
method of data analysis in this study used descriptive quantitative methods. The lowest
specific fuel consumption and specific gas consumption occurred at 100% load of 0.240
liter/kWh and 0.008 MMbtu/kWh unit 3 and unit 7 at 0.247 liter/kWh and 0.008
MMbtu/kWh after 36000 hours of an overhaul. The lowest heat rate when using gas fuel
(LNG) of 2028.427 kCal/liter in unit 7 occurred after 36000 hours of the overhaul. The
highest thermal efficiency when using diesel fuel is 39.81% after the overhaul of 36000
hours in unit 3 PLTDG, while the highest thermal efficiency when using gas fuel (LNG)
is 42.4% after the overhaul of 36000 hours in unit 7 PLTDG. The use of gas fuel (LNG)
is better than diesel fuel (HSD).
