Abstract

For the digital substation based on IEC61850 communication standards, this paper presents a novel scheme of distributed busbar protection. According to the technical characteristics of digital substation, the configuration of distributed busbar protection without central unit is constructed; the requirements of data communication between merging units (MU) and distributed busbar protection units are analyzed and the process bus based on Ethernet is designed; last, the percentage differential algorithm for distributed busbar protection is introduced. Analysis shows that the proposed scheme is a simple, high reliable and feasible distributed busbar protection for digital substation.
