Abstract
Kontinuitas pasokan daya listrik pada suatu industri sangat
diperlukan untuk menjamin terlaksananya proses produksi yang ada.
Kenyataannya, kadang kala proses tersebut terganggu akibat kurangnya
daya listrik yang disalurkan oleh pembangkit. Sehingga industri tersebut
harus menambah unit pembangkit. Namun untuk memperoleh proper
emas perusahaan, pembangkit yang dimiliki harus lebih ramah
lingkungan. Pemakaian Distributed Generation (DG) dengan bahan
bakar Reneweble Energy merupakan solusi yang dapat diambil.
Penambahan DG pada jaringan dapat mempengaruhi sistem
proteksi yang ada. Penentuan lokasi DG yang akan dipasang harus
benar-benar diperhatikan agar pengaruh tersebut dapat dikurangi. Dalam
tugas akhir ini, penentuan lokasi DG didasarkan pada nilai Protection
Coordination Index (PCI) pada kandidat bus. Terdapat dua langkah
untuk menentukan nilai PCI ini. Pertama yaitu memastikan seting
koordinasi proteksi sudah tepat. Langkah kedua adalah mencari nilai
Coordination Time Interval (CTI) dengan cara mengetahui nilai arus
hubung singkat pada setiap kandidat bus. Nilai PCI yang terbesar
mengindikasikan bahwa DG mempunyai pengaruh yang paling sedikit.
Evaluasi ini dilakukan di sistem distribusi PT. Pertamina RU V
Balikpapan dengan jumlah kandidat bus sebanyak lima buah yaitu Bus
1HT, Bus D, Bus C, Bus B dan Bus A. Dari hasil simulasi dan analisa
DG dengan kapasitas 5 MVA, nilai PCI terbesar berada di bus B yaitu
sebesar 185,15. Sedangkan nilai terkecil berada di bus 1HT sebesar
hanya 68,49. Dengan nilai ini, bus B dapat direkomendasikan apabila
PT. Pertamina RU V Balikpapn ingin memasang sebuah DG kapasitas 5
MVA.
===================================================================================================
Continuity of electrical power supply in an industry
indispensable to guarantee the implementation of production processes.
In fact, sometimes the process was interrupted due to the lack of
electrical power supplied so must be increase their generating units.
However, owned plant to be more environmentally friendly. Distributed
Generation (DG) with Renewable Energy is a solution to solved it.
Injecting DG can be affected the existing protection system.
Determination of DG location that will be installed must be properly
addressed so that the effect can be reduced. In this paper, the
determination DG location is based on the value of Coordination
Protection Index (PCI). There are two steps to determine the value of
PCI. The first is to make sure the settings are correct on protection
coordination. The second step is to look for the value of Coordination
Time Interval (CTI) by knowing the value of short circuit current. The
largest PCI value was indicates that the DG has the least influence.
The evaluation is tested on distribution system PT. Pertamina
RU V Balikpapan with five candidates buses are Bus 1HT, Bus D, Bus
C, Bus B, and Bus A. From the simulation results and analysis of the DG
with the capacity of 5 MVA, the biggest PCI value was in the bus B is
equal to 185,15. While, the smallest PCI value was in the bus 1HT for
only 68.49. With this value, the bus B can be recommended if PT.
Pertamina RU V Balikpapn want to install a 5 MVA DG.
