<br/><br/> Traditional  Provincial  Electricity  Authority  (PEA)  distribution  system  is  radial  in  nature  and  supplied  through  substations.  The  presence  of  distributed  generation  (DG)  provides  considerable  benefits  from  both  engineering  and  economic  viewpoints.  However,  the  existing network was not designed for its integration. Protection selectivity is altered in the magnitude,  duration  and  direction  of  fault  current  which  may  lead  to  problems  related  to  incorrect operation. This thesis presents the impacts of DG on the protection system in PEA distribution system using  DIgSILENT  PowerFactory  as  a  tool.  The  study  divided  into  five  case  studies,  considering sizes and connection position of a synchronous DG. The expected result can be a beneficial technical guideline to improve PEA protection system.
