Abstract
Power flow is one of parameters to get information and analysis of electric power system, concerns to operating problems and reliability. In this research, the electric power system of geothermal generation has three generating units. The electrical energy is generated to supply for the substation and self-consumption which consists of electric motors mostly. The study was to investigate the operation effect on the first unit to the power flow on the self-consumption loads with the condition of three different scenarios. By the computations of power flow, the bus bar voltages on the three scenarios were in the normal condition, as 98% of nominal voltage. The self-consumption powers of unit 2 and unit 3 were 2.56%, and that unit 1 was 3.4% of per unit generated power. The increases of total loss on the first, second and third scenarios 3 were 395 kW, 405 kW and 406.4 kW respectively.
