End-to-End Performance Evaluation of R-SV / R-GOOSE Messages for Wide Area Protection and Control Applications

Abstract

Synchrophasor measurements play an important role in smart grid wide area protection. Recently, IEC 61850-90-5 has defined transmission of IEEE C37.118.1 synchrophasors over IEC 61850 messages. Routable versions of SV / GOOSE messages mapped to network and transport layers called R-SV / R-GOOSE have been proposed. This paper presents the performance evaluation of End-to-End (ETE) delays in R-SV / R-GOOSE messages exchanged for different wide area protection and control applications. The computational delays at publisher and subscriber are calculated using the C-based open-source framework for generating R-SV and R-GOOSE. The communication network delays are calculated by performing extensive communication network simulations using network simulation tools. Finally, the End-to-End (ETE) delay performance considering both computational and communication delays of R-SV and R-GOOSE messages for realizing different wide area control and protection applications (WAPC) are presented.
