Abstract

This research presented the impacts of distribution generation on protection coordination of Provincial Electricity Authority 22 kV distribution system. The DIgSILENT Powerfactory program was used to model and analyse protective device setting and coordination. The distribution generations size 4 MW and 8 MW were hooked at the beginning, middle and end of the distribution feeder. The three study cases were performed and considered. For observation of impact of fault current contribution to traditional of protective device and how to do these factors it affected the protection coordination. The obtained results were concluded for each case. Finally, this research gave the suggestion and some solutions for suitable type or characteristic of protection device
