IEC 61850 GOOSE MESSAGING APPLICATIONS IN DISTRIBUTION NETWORK PROTECTION AND AUTOMATION

Abstract

Introducing distributed generators into distribution networks creates problems for protection systems like electric island formations or protection blinding. Possible solutions utilizing communication aided automation in IEC 61850 standard are presented in following paper. A hybrid adaptive islanding detection method and advanced network automation features in form of adaptive protection and distribution management system (DMS) are demonstrated. The results obtained through hardware-in-the-loop simulations using OPAL-RT simulator and SEL 421 relays show that presented functionalities can augment overall microgrid reliability.
