Accelerating the protection schemes through IEC 61850 protocols

Abstract

IEC61850 protocols aim to reduce the data management with a bandwidth that does not present any issues. Fast tripping protection schemes using IEC 61850 will lead to network flooding, high delay, and reduced network security. The study provides propagation characteristics of traveling wave with extra high-speed busbar protection in compliance with IEC 61850 technique. This paper analyzes the process bus and suggests two methods in order to achieve the intended fast protection with IEC 61850. The simulation of the suggested methods based on the OPNET Modeler has proven that these methods can solve the network flooding problem in Ethernet and band-limited channels such as WLAN. This study will pave the way for researchers to reuse the traveling waves for fast protection with IEC 61850. In this paper, the simulation results of the case study busbar protection using transient signal (traveling wave) based on IEC 61850 network system configurations using OPNET Modeler simulation software were presented and the influence of data rate, a number of MUs sharing process bus and delay characteristics of these system configurations were evaluated.
