Abstract
Transformasi energi menyebabkan meningkatnya kebutuhan energi listrik di sektor industri. Hal ini menjadikan sistem tenaga listrik sebagai bagian yang sangat penting untuk menopang berbagai proses yang terjadi di industri. Dalam sistem tenaga listrik, arus lebih menjadi salah satu gangguan yang paling umum terjadi. Gangguan ini bisa disebabkan karena adanya overload maupun hubung singkat pada sistem. PT. Pertamina RU V Balikpapan sebagai salah satu perusahaan milik negara yang bergerak di bidang pengolahan minyak dan gas bumi memiliki peran yang sangat penting dalam menjaga pasokan bahan bakar nasional. Kondisi seperti ini tentu memerlukan sistem pengaman tenaga listrik yang baik agar ketersediaan suplai energi listrik tetap terjaga. Dalam upaya meningkatkan keandalan suplai daya listrik, perusahaan mengembangkan sistem kelistrikan yang terintegrasi dengan jaringan PLN 150 kV. Dengan adanya integrasi baru ini memerlukan pengaturan koordinasi rele proteksi terhadap arus lebih agar dapat bekerja secara optimal. Pada tugas akhir ini metode numerical computation akan digunakan sebagai metode otomatisasi dalam pengaturan rele proteksi. Metode ini bertujuan untuk mempermudah dan mempersingkat waktu proses pengaturan rele arus lebih inverse pada sistem kelistrikan radial. Hasil yang diperoleh adalah Time Dial Setting (TDS) dan Time-Current Characteristic Curve (TCC). Sebelumnya, koordinasi proteksi pada system kelistrikan PT. Pertamina RU V Balikpapan telah dievaluasi dengan mempertimbangkan integrasi PLN 150 kV. Selain itu, penelitian menggunakan metode adaptive modified firefly algorithm juga telah dilakukan pada sistem yang baru terintegrasi ini.

Energy transformation causes an increase in the need for electrical energy in the industrial sector. This makes the electric power system a very important part to support various processes that occur in industry. In electric power systems, overcurrent is one of the most common disturbances. This disturbance can be caused by an overload or short circuit in the system. PT. Pertamina RU V Balikpapan as one of the state-owned companies engaged in oil and gas processing has a very important role in maintaining the national fuel supply. Conditions like this certainly require a good electrical power safety system so that the availability of electrical energy supply is maintained. In an effort to improve the reliability of electric power supply, the company developed an integrated electrical system with the 150 kV PLN network. With this new integration, it is necessary to regulate the coordination of the overcurrent protection relays in order to work optimally. In this final project, the numerical computation method will be used as an automation method in the protection relay settings. This method aims to simplify and shorten the processing time of the inverse overcurrent relay setting in the radial electrical system. The results are Time Dial Setting (TDS) and Time-Current Characteristic Curve (TCC). Previously, the protection coordination in the electrical system of PT. Pertamina RU V Balikpapan has been evaluated by considering the integration of the 150 kV PLN. In addition, research using the adaptive modified firefly algorithm method has also been carried out on this newly integrated system
