Increment of Fault Current due to integration of Distributed Generation and its impact on Distribution Network protection

One of the new technologies in generating power near distribution system is called distributed generation which has supportive and destructive characteristics to protection. increasing level fault current protective equipment that affects existing time intermission coordination overcurrent relay. In addition increment fault, it also alters radial nature cause bidirectional rather than unidirectional. Integration network causes effect, reliability drop, security protection system. The failure be contingent on type, size, location number generation. This can a great damage electrical with miss operations devices. main aim this paper analysis due integration concerns solar generation, wind combination generations at time. conducts by its impact modeling are conducted 15KV feeder Debre Markos town. covered ling ground, line three phase their for types. After increased 0.529KA phase, 0.74KA 0.467KA 0.523KA ground. confirms designing without forecasting future demand electric users give additional requirement. As result, after have value terms
