Abstract

ABSTRACT Power flow analysis is important in planning in order to get a good electric power system. In planning the electrical system for the Tujuh Bukit Power System project with a 20kV system network located in Banyuwangi, East Java, a power flow simulation for a single line diagram will be carried out using the ETAP 12.6 software with the Newton Raphson method. The simulation results which consist of 22 buses show a voltage drop on the 0.4kV_ADR MCC Busbar2 bus and 0.4kV_50-MCC-01 Busbar2 bus. As a system improvement, the 0.4kV_ADR MCC Busbar2 bus will be installed with a 500 kVar capacitor bank to raise the voltage profile from 376.3 V to 385.56 V. While on the 0.4kV_50-MCC-01 Busbar2 bus, a 100 kVar capacitor bank is required to increase the voltage from 382.2 V to 384.16 V. After the repair, the power supplied to the system is 3589.6 kVA with a power factor of 90.5% lagging. As well as the reduction in the total value of system power losses from 58.1 kW + 242.2 kVar to 49.3 kW + 200.8 kVar. Keywords: Power flow, Netwon Rapshon, Simulation, Software ETAP 12.6

Abstract

ABSTRACT In general, the good or bad of the distribution and distribution system of electric power is mainly in terms of the quality of the voltage received by consumers. One way to increase efficiency is to reduce power loss and minimize voltage drop on the network. The results showed that the voltage drop that occurred at the PJXS substation PT. PLN ULP Bogor Timur is caused by two main problems, the first is that the location is far from the distribution substation and around the location has high loads. Prior to the implementation of the load rupture, the magnitude of the voltage drop that occurred at the PJXS substation PT. PLN ULP Bogor Timur has passed the ideal service limit set by PT PLN Persero, which is a minimum of 10% or 198 volts from the nominal voltage of the low-voltage network, which is 220 volts. The results of this new department have a good voltage value that is not below the standard voltage drop set by PLN, namely the service voltage value has a maximum value of 5% and a minimum of 10% of the nominal voltage of 220 Volts.
