Abstract
Perusahaan oil & gas seperti PT. Pertamina (Persero) RU VI
Balongan membutuhkan suplai daya listrik yang baik untuk menjamin
keandalan dan kontinuitas sistem kelistrikan. Sistem kelistrikan haruslah
memiliki koordinasi proteksi yang baik untuk menjaga sistem kelistrikan
dari gangguan yang mungkin terjadi. Gangguan pada sistem kelistrikan
sangat bervariasi dari besar hingga jenisnya. Koordinasi proteksi yang
baik dapat mengatasi daerah gangguan dan mencegah pemadaman (black
out) di daerah lain. Untuk menjaga dan meningkatkan performa sistem
proteksi perlu dilakukan suatu studi terhadap koordinasi rele pengaman
yang terpasang.
Maka dari itu, tugas akhir ini bertujuan untuk menganalisis terhadap
koordinasi rele pengaman pada pabrik PT. Pertamina (Persero) RU VI
Balongan. Dari hasil plot koordinasi kurva arus waktu kondisi existing
dapat diketahui bahwa terdapat miss-coordination pada tipikal koordinasi
yang dianalisis. Dari hasil analisis dan perhitungan manual dalam tugas
akhir ini, direkomendasikan penyetelan ulang rele arus lebih dan rele arus
lebih gangguan ke tanah. Diharapkan dengan resetting rele dapat
mengamankan sistem kelistrikan di PT.Pertamina (Persero) RU VI
Balongan.

Oil & gas companies such as PT. Pertamina (Persero) RU VI
Balongan need a good supply of electrical power to guarantee the
reliability and continuity of the electrical system. The electrical system
must have good coordination to maintain the protection of the electrical
system disturbances may occur. Disturbances in the electrical system
varies from large to its kind. Good protection coordination can overcome
interference area and prevent blackouts in other areas. To maintain and
improve the performance of the protection system needs to be carried out
a study on the safety relay coordination installed.
Therefore, this thesis aims to analyze the coordination of safety
relays on the PT. Pertamina (Persero) RU VI Balongan. From the results
of a flow curve plot coordination existing condition can be seen that there
is a miss-coordination in typical coordination analyzed. From the
analysis and manual calculations in this thesis, it is recommended
resetting overcurrent relay and relay overcurrent interruption to the
ground. It is expected to be able to secure the relay resetting the electrical
system in PT.Pertamina (Persero) RU VI Balongan.
