Advanced communication system in substation for integrated protection

Abstract

This paper proposes an advanced substation integrated protection communication system based on the latest development in power system. The integrated protection communication system within a substation comprises a number of major components such as the merging unit, communication network and integrated protection unit. The design and capability evaluation of the communication network based on IEC61850 are focused on. Results show that huge information from 4 merging units can be transmitted real-time via adopting 100 Mbit/s optical fiber in a substation, and the proposed communication network is able to achieve required performance.
