IEC 61850 Source Code Implementation for Accessing IED Data

Mini S. Thomas, Senior Member, Ikbal Ali and Nitin Gupta

Substations are opting IEC 61850 (International Electrotechnical Commission) interoperable protocol as the protocol helps in resolving most of the challenges related to IED (Intelligent Electronic Device) integration for providing an interoperable communication at bay level. However, it is still challenging for client applications to acquire data from IEC 61850 compliant IEDs and do further processing. The aim of this paper is to demonstrate how an IEC 61850 source code application running at station level can be configured to acquire data from the IEDs installed at bay level. The paper also describes the role of Manufacturing Message Specification (MMS) in establishing a communication between the client and the server (IED).
