Abstract

Penetration of Distributed Generations (DGs) has made traditional distribution protection schemes mostly ineffective. Sophisticated protection schemes cannot be implemented using fuses, reclosers and Miniature Circuit Breakers (MCBs). Limited numbers of overcurrent relays are used in distribution systems. Voltage based protection is often not economical for distribution systems. Economics often limits the use of sophisticated relays in distribution systems. Smart Meters (SMs) are available at various load points in a distribution system. SMs are equipped with measuring, calculation and communication capabilities. This paper proposes the utilization of SMs in distribution system protection. The possible applications of SMs in high impedance faults (HIF), overcurrent, reverse power, series arcing and under-voltage protection of distribution systems are identified in this paper. One of the advantages of the proposed approach is that voltage-based protection can also be implemented using SMs. The effectiveness of the proposed SM-based protection has been demonstrated by simulating a European low voltage test feeder comprising of 906 buses in PSCAD. As a part of hardware validation, protection functionalities have been implemented in a commercial SM. The SM trips a Molded Case Circuit Breaker (MCCB) upon detecting a fault. Cost-Benefit analysis falls out of the scope of this paper.
