Abstract :
In distributing electric power, PLN must be able to distribute energy with good
quality, the parameters of end voltage level and Power losses are two of the factors that
need attention. At PLN ULP Nabire Masohi and Akasia Feeder Systems after carrying
out a load flow simulation on Digsilent Powerfactory 15.1, there is a voltage at the end
of Masohi Feeder 19,840 Volts and Akasia 19,698 volts. For Masohi Power Losses 0.09
MW, and Akasia 0.01 MW. The author intends to conduct research to improve the
voltage value and power loss at the Masohi and Akasia feeders by using the maneuver
method where the Masohi and Akasia feeders meet with the Akasia Ujung load to be
moved to Masohi feeders by means of Close LBS SMK2 and Open Recloser BMW.
The simulation results after maneuvering the tip voltage of the Masohi Feeder is 19,825
Volts and the Acacia Feeder is 19,809 Volt. The value of Power Losses has improved,
namely the Masohi Feeder to 0.01 MW and the Akasia Feeder to 0.00 MW. The
percentage of voltage drop on the Masohi feeder was relatively the same in good
condition, namely before and after the range of 0.5-0.6%, while for the Akasia feeder
the percentage of voltage drop had improved from before being maneuvered to 1.27%
and after being maneuvered to 0.72%. The voltage percentage standard is according to
SPLN 72 TH 1987, the limit is 5%, while the value after the maneuver is still according
to the standard.
