Title: Gantry Transposition to Reduce Unbalance Phenomena in Long Transmission and Small Loading Substations in Central Kalimantan
Abstract: According to the basic concept, the transposition of transmission line phases is intended to reduce the current and voltage unbalances in the normal operation of a power system. Transposition is generally implemented by dividing the transmission line into several sections to reverse the phase using a transposition tower. In this paper, transposition was implemented on the gantry at the substation. It makes the method simpler, faster, and more economical. There is no need for a transposition tower. Simulations were carried out at the end of radial lines in Central Kalimantan to compare the gantry transposition and the transposition using the transposition tower before and after reactor operation due to high voltage phenomena. The results show that gantry transposition can minimize losses, improve protection sensitivity, and improve electricity quality. Transposition in the substation gantry is recommended at lines Pangkalan Bun-Nanga Bulik (S-R-T), Nanga Bulik-Sukamara (S-T-R), Pangkalan Bun-Sukamara (S-T-R), and Bagendang-Kuala Pambuang (S-R-T). According to simulation results, the gantry transposition can reduce the unbalance at the end of radial lines of Sukamara substation from 4.83% to 0.75% and Kuala Pambuang substation from 3.57% to 0.61% (night peak load).
