Laboratory testing of the communication based protection relays

Abstract

The proper operation of control and protection applications in Substation Automation System (SAS) demands very high-speed and reliable communications that has being achieved by using IEC 61850. Moreover, the practical implementation and testing of protection scheme requires a communication system that can be conventional or high-speed peer-to-peer communication. This paper presents the evaluation of the performance advantage of GOOSE (Generic Object Oriented Substation Event) message over its conventional hard-wired counterpart for the same relays protection
