Abstract
Dalam dunia industri, kontinuitas proses produksi sangat
ditentukan oleh kontinuitas ketersediaan listrik, kontinuitas tersebut
dapat dijaga dengan menggunakan sistem proteksi tenaga listrik yang
efektif dan selektif. Pada pabrik kimia, selain menjaga kontinuitas
proses produksi, kontinuitas kelistrikan juga dibutuhkan untuk menjaga
keamanan akibat bahan-bahan berbahaya yang dijadikan bahan dasar
produksi. Seiring berjalannya waktu, PT. Pupuk Sriwijaya (Pusri)
Palembang melakukan ekspansi dengan membangun pabrik baru yakni
Pabrik P2B dengan generator 1x35 MW. Keadaan tersebut membuat
setting koordinasi proteksi pada PT. Pusri harus mengalami perubahan
dari keadaan sebelumnya untuk tetap menjaga faktor selektifitas dan
efektifitas. Oleh karena itu, harus dilakukan suatu studi koordinasi
proteksi untuk meningkatkan keandalan sistem proteksi pada PT. Pusri
Palembang. Sehubungan dengan hal tersebut, tugas akhir ini difokuskan
untuk membahas studi koordinasi proteksi untuk mengetahui setting rele
yang tepat setelah dilakukan penambahan beban Pabrik P2B dan
Generator 1x35 MW. Analisis aliran daya dan hubung singkat
diperlukan untuk mendapatkan koordinasi proteksi yang tepat.
Gradingtime antar rele diatur sesuai standar IEEE 242 yaitu 0,2 detik
hingga 0,3 detik dan time delay dikoordinasikan sehingga rele tersebut
dapat bekerja dengan tepat. Hasil koordinasi proteksi ini dapat
melindungi dari gangguan berupa arus beban lebih dan arus hubung
singkat.

In the industrial world, the continuity of the production is
determined by the availability of electrical continuity, it can be filled by
using the electric power system protection to fulfill the factor of
effectiveness and selective. In chemical factory, the reability and
continuity have a great effect of their safety to keep the hazardous
materials which used for the basics of production. Now a day, PT.
Pupuk Sriwijaya (Pusri) Palembang expanding their factory by build a
new plant with a generator 1x35 MW. These circumstances make PT.
Pusri have to change the setting of protection coordination from its
previous state to keep the selectivity and effectiveness factors. A study of
protection coordination is needed to improve the reliability of the
protection system in PT. Pusri Palembang. This thesis is focused on
discussing the protection coordination studies to determine the
appropriate relay setting after the addition of plant load P2B and 1x35
MW Generator. The analysis of power flow and short circuit protection
is required to obtain the proper coordination. Grading time between
relay set according to the IEEE 242 standard, namely 0.2 seconds to 0.3
seconds and a time delay relay is coordinated so that it can work like we
needed. The protection coordination have to protect from disruption of
current overload and short circuit current.
