GOOSE Publishing and Receiving Operations of IEC 61850 Enabled IEDs

Substation automation protocols and architectures are used to overcome various limitations of power system automation while implementing various network topologies. Presently the network topologies that are being used are Ethernet, TCP/IP, wide area network (WAN) and computers. In substation automation sector a new protocol IEC 61850 has been released by International Electrotechnical Commission or IEC for global use. This paper is focusing on IEC 61850 standard GOOSE messaging operations of IEDs. Basic idea of IEC 61850 standard, SCL language and application protocol GOOSE has been discussed in this paper. Communicating devices IEDs enabled with IEC standards have been shown with operations in publisher and subscriber mode. Laboratory setup with two IEDs communicating in an Ethernet network has been implemented here. The test results of hardware setup are showing GOOSE sending and receiving operations of the two IEDs through the Ethernet switch they are connected with. This paper will help the readers to get a basic understanding about IEC 61850 standards, IED operations and GOOSE messaging operations in real time.
