PERENCANAAN GARDU DISTRIBUSI TEGANGAN MENENGAH 20 kV DI INDONESIA PORT CORPORATION (IPC) TELUK BAYUR

Abstract

Teluk Bayur is also one of the projected port  be a sea port that supports toll in accordance with the government program. At this time the distribution of power systems in the  supply of Substation (GH) PLN with a capacity of 30 MVA. Of GH are 6 kWh PT. Pelindo II that each - each subscribing low voltage (TR) with a total of 1458.10 kVA power radially, besides that there are cranes, each using their own generator (genset). With the radial system resulting voltage drop on the lighting at night, and the distribution network is also irregular. With the ring open system that would unite the entire load to the distribution system, in addition to improving the electrical system is reliable and power on the crane ration of electricity, distribution substation planning needs to be done with one medium voltage customers. The load capacity for the distribution of 12 425 kVA substations, distribution substations will be planned level two, level one there is a backup generator (genset) 1500 kVA transformer step-up 0.4 / 20 kV berkapasita 4000 kVA and on two levels there LVMDP cubicle panels and MVMDP. By using a single power supply of medium voltage distribution substations region Teluk Bayur port can save on the electricity bill payment, due to the large power class B3 rate less than the rate class B2 little helpless.
