Abstract
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% and 90% power DG obtained a voltage drop at the end of the line of y and 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.
