Abstract

Perusahaaan VICO Indonesia adalah suatu perusahaan asing yang bergerak dibidang pengolahan minyak dan gas bumi di Kalimantan Timur, Indonesia. VICO Indonesia memiliki 4 Lapangan pengolahan minyak dan gas yaitu Muara Badak, Nilam, Semberah, dan Mutiara, sehingga di VICO Indonesia pasti mempunyai 4 plan sistem kelistrikan disetiap area tersebut. Di VICO Indonesia sering terjadi Black Out (Sistem Kelistrikanya Mati) biasanya diakibatkan Karena gangguan interkoneksi disalah satu area di VICO itu sendiri, sehingga jika satu area terganggu maka area lain juga ikut terganggu. Namun dalam pelayanannya, peralatan pengaman yang dimiliki oleh VICO Indonesia masih belum terkoordinasi dengan baik. Dari hasil plot koordinasi kurva arus waktu kondisi existing dapat diketahui bahwa terdapat misscoordination dan overlaping. Melalui hasil analisis dan perhitungan manual direkomendasikan penyetelan pick up rele arus lebih dan penyetelan gradding time rele. Rele yang perlu disetel ulang adalah rele arus lebih gangguan fasa (Over Current Relay) dan rele arus lebih gangguan tanah (Ground Fault Relay). Pada Tugas Akhir ini akan dilakukan evaluasi koordinasi proteksi yang ada seperti pengaman arus lebih (Over Current Relay) dan rele pengaman gangguan tanah (Ground Fault Relay) serta menggambarkan kurva karakteristik arus waktu pada perusahaan VICO Indonesia. Analisis koordinasi kurva proteksi ini diharapkan dapat mencegah atau membatasi kerusakan jaringan beserta peralatannya. ============================================================================================================ VICO Indonesia factory is a foreign company engaged in the processing of oil and gas in East Kalimantan, Indonesia. VICO Indonesia has four oil refineries and gas field of Muara Badak, Patchouli, Semberah, and Pearl, so in VICO Indonesia has had 4 plan in every area of the electrical system. The VICO Indonesia often occurs Black Out (Elecrical Systems Dead) is usually caused Because interconnect disturbances in one area in VICO itself, so that if one area is disrupted other areas also disrupted. But in his ministry, safety equipment owned by VICO Indonesia is still not well coordinated. From the results of the coordination plot a current curve existing condition is known that there misscoordination and overlapping. Through the analysis and manual calculation of the adjustment recommended overcurrent relay pick up and adjustment gradding time relay. Rele that needs to be reset is the relay overcurrent phase disorder (Over Current Relay) and ground fault overcurrent relay (Ground Fault Relay). In this final project will be evaluated coordinating existing protection as a safety overcurrent (Over Current Relay) and safety rele soil disturbance (Ground Fault Relay) and describes the current characteristic curve at the time the company VICO Indonesia. Analysis of protection coordination curve is expected to prevent or limit damage to the network and its equipment.
