Abstract
Sistem kelistrikan PT. Pupuk Kalimantan Timur II ( PKT II) telah di
integrasikan sejak tahun 2009 untuk meningkatkan kontinuitas dan
keandalan sistem bagi seluruh plant. Sehingga terdapat penambahan
beban dan pembangkit baru. Penambahan beban dan pembangkit baru
akan memberikan arus hubung singkat yang besar pada kelistrikan PT.
Pupuk Kalimantan Timur II ( PKT II). Saat terjadi arus gannguan
hubung singkat ½ cycle pada switchgear PT. Pupuk Kalimantan Timur
II ( PKT II), arus gangguan tersebut melebihi rating kapasitasnya,
dimana kapasitas ratingnya sebesar 37.8 kA peak, sedangkan arus
hubung singkat ½ cycle pada switchgear sebesar 67.41 kA peak. Oleh
sebab itu digunakan pemasangan SISFCL untuk membatasi arus hubung
singkat tersebut. pemasangan SISFCL ini dipasang pada feeder
transformator TR-K2-02 dan feeder generator GTG-K2, dimana feederfeeder
ini yang menyumbangkan arus hubung singkat terbesar. Akibat
pemasangan SISFCL ini dapat mengurangi besarnya arus hubung
singkat dari 67.41 kA peak menjadi 35.751 kA peak.Pemasangan
SISFCL menunjukkann arus hubung singkat semakin berkurang
sehingga mengakibatkan perubahan koordinasi proteksi arus lebih. Studi
koordinasi ini digunakan untuk mengetahui sistem kelistikan ini apakah
sistem pengamannya bekerja dengan baik. Hasil analisa ini ditampilkan
dalam bentuk kurva time current characteristic (TCC)
====================================================================================
Electrical systems PT Pupuk Kalimantan Timur II (PKT II) has been
integrated since 2009 to improve the continuity and reliability of the
system for the entire plant. So that there is additional load and new
generation. The addition of the load and the new generation will provide
a large short circuit currents in the electrical PT. East Kalimantan
fertilizer II (PKT II). When there is a short circuit currents fault ½ cycle
in switchgear PT. East Kalimantan fertilizer II (PKT II), the fault current
exceeds the rating capacity, where the capacity of its rating of 37.8 kA
peak, while the short circuit current in the switchgear ½ cycle of 67.41
kA peak. Therefore, using mounting SISFCL for limitting the short
circuit current. SISFCL installation is mounted on the feeder transformer
TR-K2-02 and feeder generator GTG-K2, where feeder-feeder who
supply the largest short-circuit current. Due to the installation of this
SISFCL can reduce the amount of short circuit current of 67.41 kA peak
into 35 751 kA peak. Installation SISFCL cause short circuit current
decrease and make a different coordination overcurrent protection. This
coordination studies are used to determine whether the electrical system
works well. The analysis results are displayed in the form of currenttime
curve characteristic (TCC)
