Reconciliation Process

This study aims to determine the loss / power loss in the nijang feeder through the energy reconciliation process, simulation of the ETAP 12.6 program, and manual calculations. The benefits of this research can be used as a basis for consideration of the improvement efforts that should be carried out to minimize power losses in the medium voltage distribution network of Nijang feeders. The method used is quantitative research method because it takes data from the measurement of the transaction point which is then compared with the results in the simulation program ETAP 12.6 and manual calculations. The results showed that the power loss (kWh) resulted from 3 processes showed that the energy reconciliation process resulted in a greater power loss, namely 10,657 kWh, the ETAP 12.6 simulation resulted in a power loss of 3049 kWh and in manual calculations it resulted in losses. power of 4199 kWh, from the results of the research it can be seen that in the simulation process ETAP 12.6 and manual calculations only calculate power losses due to technical causes, while the energy reconciliation process includes technical and non-technical causes. It is hoped that this research can support efforts to improve power losses / losses in the PT PLN (Persero) UP3 Sumbawa environment.

Quantitative Research Method

This study looked at the condition of power loss and falling voltage after the evaluation of the medium voltage network 20 kV after the earthquake disaster in South Halmahera district, especially in labuha extension on Bacan island The method used in this study is a quantitative research method with data collection done which is then simulated using ETAP 12.6 software. The simulation result obtained total power loss at Labuha extension is 44.3 kW + 66.8 kVAR or 80,154 kVA of 2,445 MVA delivery power, while the presentation of power loss is 3.278%, this is still considered feasible because the power loss on the medium voltage network 20 kV is 10% while in Labuha turtles the power loss is less than 10%. While the large fall in voltage at the largest Labuha extension at the Belang-Belang distribution substation is 3.96% or 792 volts, this is due to the channel length and presentation of the load reaching 83% against the distribution tranformator and the fall in the average voltage of Labuha's purgator is 3.025% or 605 volts against the nominal voltage of 20 kV. It is still considered viable for operation due to the permitted voltage fall on the 20 kV medium voltage network which is 5%.

The Cost

Ground wire is one of the lighning protection instrument used in medium voltage distribution network with the intention to reduce interference due to lightning strikes. On the feeder Serangan the ground wire put 4 – 5 wicket. To know effective gap of ground wire is put on the feeder Serangan then used effectiveness ground wire parameters and total of disorder by lightning strikes directly or indirectly. From the analysis is obtained the effective gap on scenario 4 by 3 – 4 wicket. Choosing scenario 4 is as effective gap because seen by economic aspect, as longest gap point put of ground wire then the cost needed to use material and the installation of ground wire will be cheaper.  DOI: 10.24843/MITE.1501.05
