| Abstrak/Abstract |
Increasing of electrical demand causes the need of
more effective generation system in the distribution of power.
Distributed Generation (DG) is a generation system that can
resolve the problem. Installation of DG has complex impacts on
the distribution network such as change of the voltage profile,
short circuit current, power loss network, harmonics and
reliability of the system. Therefore, the installation of DG involves
the evaluation of protection coordination in accordance with the
size, type and placement of DG installation. In this study, the
impact of the installation of DG on the coordination of protection
on radial distribution network was studied. The distribution
system that was used in this study is data from the distribution
system of PT. PLN (Persero) Central Java Region. In general, the
installation of DG in Central Java has two configurations. First,
the installation of DG is done by connecting directly to the 20 kV
busbar substation using the express line. Second, the installation
is done by connecting DG in the feeder line. The results show that
the existing protection coordination settings still work properly
for protection coordination settings after the installation of DG. |
