IEC61850 logical node lookup service using distributed hash tables

Development of Information and Communication Technology (ICT) increases the communication capability of equipment in power system and make large number of data sources available. Flexibly and adaptive sharing of share these data sources with applications is a new challenge for the power system. This paper presents an alternate data source lookup service using IEC61850 Manufactory Messaging Specification (MMS) to collect local substation data source information and utilizing Distributed Hash Table (DHT) to share Logical Nodes addresses across the overlay network. Result of the proposed scheme is a flexible, autonomous, scalable, and robust method to address Logical Nodes across a Wide Area Network. Comparing with existing data link configuration, this solution can reduce the manual data link configuration work and enabling greater flexibility to integrate new data points. The presented platform also opens door for adaptive data acquisition needs of power system applications.
