Documentation of communication in power utility automation
This standard specifies a structure for documentation of exchanged information that is required for testing and maintaining of the devices in the utility. It is intended for equipment and Intelligent Electronic Devices (IEDS) that communicate generic object oriented events via Ethernet based communication. This standard will be complement to other documentation standards in power utility automation like, IEC 61082. The IEC 61850 based documentation has been described in Annex A.
It also intends to harmonize the documentations of the logical data flow structures based on IEC61850 communication, among different manufactures.
This international standard’s focus is mainly principle of visualization of the digital information exchanged between protection and control devices in automation system of power girds.
