Review of Modern Methods for Busbar Protection Implementation

Abstract

At present time, the introduction of digital technologies has a significant impact on the building principles of modern electrical substations. Thereby it is provided an increasing interest to the standards of the IEC 61850 series. The paper provides a comparative analysis of traditional busbar protections and options for their modern implementation carried out with the application of IEC 61850 standard. The digital model of DPBP capable of working with modern digital CTs according to the protocols of the standard family IEC 61850 has been developed.
