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.
