Abstract : The study of a distribution system is done on a radial system where the causes and effect of distributed generation (DG) are determined. The system is an industrial area or a weak power distribution system. DG presence in the system depends upon requirements by the load and as backup. A radial system for the study of voltage sag and overcurrent on different buses when connected to a distribution system with DG is analyzed and with respect to faults. However the impact of DG units on grid voltage is strongly dependent on voltage level, grid impedance and concerned grid. The protection coordination concept between protective devices located on different buses in the system is proposed. Index Terms —Distributed generation, Circuit- Breaker, power quality, protection coordination, voltage sag.
