Abstract

Sistem proteksi tenaga listrik memiliki peran yang sangat penting dalam menjamin kontinuitas proses produksi pada suatu industri. Namun, seiring berjalannya waktu maka tingkat keandalan dari peralatan sistem proteksi akan semakin menurun dan perlu diperbarui. PT. Pertamina RU III Plaju memiliki sistem proteksi eksisting yang sudah tua sehingga sering terjadi malfunction. Oleh karena itu, direncanakan melakukan penggantian peralatan proteksi untuk meningkatkan keandalan sistem proteksi sehingga kontinuitas proses produksi tetap optimal. Pada setting rele eksisting hanya ada setting invers saja, sehingga saat melakukan penggantian rele diperlukan studi koordinasi proteksi untuk mendapatkan setting yang sesuai. Sehubungan dengan hal tersebut, maka tugas akhir ini difokuskan pada studi koordinasi proteksi untuk mengetahui setting rele yang tepat setelah penggantian peralatan sistem proteksi di PT. Pertamina RU III Plaju. Dalam melakukan koordinasi proteksi diperlukan analisis aliran daya dan hubung singkat. Grading time antar rele diatur sesuai standar IEEE 242 yaitu 0,2 s/d 0,3 s dan time delay dikoordinasikan sehingga rele tersebut dapat bekerja dengan benar. Hasil koordinasi proteksi ini dapat melindungi dari gangguan berupa beban lebih dan hubung singkat. ========================================================================================================= Electric power protection system has a very important role in ensuring continuity in an industrial production process. However, over time the level of reliability of the equipment protection system will decrease and need to be updated. PT. Pertamina RU III Plaju have existing protection systems which are old so often malfunction occurs. Therefore, the planned replacement of protective equipment to improve the reliability of the protection system so that the continuity of the production process remains optimal. In the existing relay settings only inverse setting only, so while doing the replacement of relay, protection coordination studies is needed to get the appropriate settings. In connection with this, the final project is focused on protection coordination studies to determine the proper relay settings after replacement protection system equipment in PT. Pertamina RU III Plaju. The coordination of protection required power flow and short circuit analysis. Grading time between relay set according to the IEEE 242 standard is 0.2 to 0.3 s and the time delay can be coordinated so that the relay is working correctly. The coordination of this protection can protect from fault in the form of overload and short circuit.
