Feasibility Study on the Operation of Toboali Substation to Reduce the Use of Fossil Fuels as Power Plants and Energy Loss by Computer Simulation

Abstract

This study discussed the analysis of load flow before and after the Toboali Substation (GI Toboali) - that is still in development process stage when the paper is written-. This study was operated in a computer simulation using ETAP Software. The Toboali substation needs to be built because Toboali diesel power plant will be shut down because the Toboali diesel power plant is a diesel power plant leased from PT. Megapower. From the simulation results it was found that before the Toboali substation operated the energy loss was 3,895.7 MWh/year and after the Toboali Substation operated an energy loss was 3,377.5 MWh/year and will reduce 20 tons/day usage of biodiesel. It is expected that when the Toboali substation operates it will reduce the energy loss and electricity dependence of the region on fossil energi and also it will increase power system reliability.
