OPTIMASI PENGATURAN PEMBANGKITAN DAYA REAKTIF MENGGUNAKAN TAP CHANGER TRANSFORMER UNTUK MEMINIMALISASI RUGI-RUGI DAYA AKTIF SISTEM 150 kV SUMBAR-RIAU

Abstract

This paper out tell optimistic technique delivery of power to get minimum power loss by arranging Tap Changer Transformer at line.Optimistic Delivery of active and reactive power needed to minimize power loss is so that got by economic operating expenses from an power system. The reactive power optimistic more is difficult solved to be compared to active power which owning many complex link between variable.Correct power reactive allocation in system can yield optimum condition that is condition of where minimum transmission loss. To get optimum condition in this paper out is done by arrangement of reactive power by Tap Changer Transformer change positian, so that assess tension at busbar come near is samely. Arrangement of tap transformer  in principle is change line admitansi value, so that minimum line loss. Calculation of Power flows system used by Newton Raphson method with Sumbar-Riau power system application 15 bus 16 line.
