This study took a case study at PT. PLN (Persero) APJ Area Bandung with the subject raised is the installation of Distribution Generators on the distribution line of 20 kV. The purpose of this study was to determine the effect of generator installation Distribution of stability on a system of 20 kV distribution with load conditions is considered balanced. The reason for conducting this research is to find out how far DG can maintain stability on each bus. The method used in this study is to compare the results of the simulation of power flow and short circuit interference using ETAP Power System software. The results obtained from the power flow simulation before installation DG voltage drop at the end of the line. While the three phase short circuit fault current before the DG installation at the beginning of the line is x. After installation of DG with an injection of 50% power DG obtained a voltage drop at the end of the line of y and a fault current at the beginning of the line of z. While the injection of 90% of the power obtained by the voltage drop at the end of the line is v and the fault current at the beginning of the line is w. The results of the study show that with the injection of DG can increase the voltage profile on the line. Likewise, the interference current has increased, but it can be overcome by placing the location of the DG from the fault site. © Published under licence by IOP Publishing Ltd.
