Abstract: - In contrast to the conventional approach of design of a distance relay based on off-line worst-case studies, the adaptive approach adjusts the reach setting of the relay according to the on-line power system conditions and signal availability. The proposed adaptive relay, automatically adjusts its operation based on the acquisition of the data from distance relay of adjacent line and status of adjacent line from line circuit breaker IED (Intelligent Electronic Device). The results of a simulation study are presented to quantitatively compare the conventional and adaptive approaches, taking into account the effects of transmission line operating conditions, mutual coupling between parallel lines and variations in the system external to the protected line. The evaluation test results have proved the efficacy of adaptive relay over the conventional distance relay.
Keywords: Adaptive relaying, distance measurement, mutual coupling, quadrilateral trip characteristic, zones
