dc.description.abstractConventional methods of distance protection relays measure an impedance. Based on voltages and currents, the relay determines the distance between relay and fault location and enables selective fault clearing. Closed-ring structures increase the grid capacity for connecting distributed energy resources as inter infeeds. However, closed-ring structures and inter infeeds can cause malfunctions of conventional distance protection and disturb the proper operation of non-directional short-circuit current indicators particularly. This paper proposes a voltage-less distance protection method which complies with closed loop structures and inter infeeds properly in case of unbalanced faults. The proposed approach is based on current comparison and negative-sequence system quantities. Thus, it remains unaffected from inter infeeds and fault resistances. The approach serves as a supplement to conventional distance protection methods which are applied for symmetrical faults and if the closed-ring structure is dissolved. Finally, the paper presents a protection grading strategy that significantly reduces the average fault clearing time.
