Abstract

Short circuit merupakan salah satu penyebab utama gangguan pada sistem kelistrikan. Berdasarkan standar IEEE 242 diperlukan suatu sistem proteksi untuk menanggulanginya. Tambang emas di Banyuwangi merupakan pabrik baru yang menggunakan sumber listrik berupa multi generator terdiri dari 15 pembangkit mikrohidro dengan kapasitas 10MW. Oleh karena itu, diperlukan suatu perancangan sistem proteksi yang handal dan aman pada tambang emas di Banyuwangi. Menurut standar IEEE 242-2001 koordinasi proteksi dilakukan dengan cara analisis short circut, setting rele arus, dan setting LVCB. Perancangan ini menggunakan pemodelan single line diagram sistem kelistrikan pada software. Variable yang dihitung yaitu arus pick up dan waktu penyalaan. Penelitian ini hanya memperhitungkan pengaman fasa. Dari hasil analisis diperoleh bahwa ada arus kontribusi yang tetap pada sistem sehingga dibutuhkan penambahan rele. Penambahan rele ini juga berguna untuk meningkatkan keakuratan lokalisasi gangguan. ======================================================================== Short circuit is one of the main causes of disturbances in the electrical system. Based on the IEEE 242 standards, required a protection system to mitigate them. Gold mine in Banyuwangi is a new plant that uses a power source in the form of multi generator consists of 15 micro hydro power plants with 10MW capacity. Therefore, we need a reliable and safety protection system design for the gold mines in Banyuwangi. According to the IEEE 242-2001 standard, protection coordination is done by short circuit analysis, current relay setting, and LVCB setting. This design uses a single line diagram modeling of the electrical system on the software. Variable that calculated are the pick-ups current and ignition timing. This study only takes into account the phase protection. The results of analysis show there is a permanent contribution current in the system so that it need additional relay. This relay is also useful to improve the accuracy of interference localization.
