Abstract :
The connection of distributed generators (DG) to distribution networks influences the performance of the networks. This paper focuses on the impact of DG on the feeder protection, specifically the impact on the overcurrent (OC) relay performance. The paper presents simulation results to show the extent of deterioration a DG can cause on the OC relay performance. The paper then presents an approach to solve this problem and restore the overcurrent relay performance.
