Utilizing possibilities of IEC 61850 and goose

This document describes the utilization of some new features offered by IEC 61850, Communication Networks and Systems in Substations. In particular, the paper looks at how horizontal communication, commonly known as GOOSE communication, between protection and control devices can be used to improve the reliability and performance of the system. Besides describing generic improvements in capacity, performance and reliability, the paper presents a practical GOOSE application, i.e. blocking based busbar protection.
