IEC 61850 communication protocol with the protection and control numerical relays for optimum substation automation system

The substation automation technologies are considered as the highlights points to innovation with the researchers and electric companies, which resulted in the development of numerous protocols and standards. The high voltage substation control system is considered as one of the main challenges to reach the optimum operating system. In the past, it's difficult to re-install the protection or control relay by a different manufacturer, to avoid the log-off the communication with the substation control system. The International Electro-Technical Commission (IEC) 61850 protocol is a new technique for the communication and remote control of the Substation Automation System (SAS). IEC 61850 protocol is a more flexible communication system for control, fast for operation, high accuracy measurements and interoperability between many different manufactures Intelligent Electronic Devices (IEDs). The Generic Object-Oriented Substation Event (GOOSE) is the light important function in IEC 61850 protocol to represent a status function from the remote IEDs to operates in the local IEDs. This paper discusses the substation automation system control depending on the IEC 61850 communication protocol for the optimum automation system. The simulation in this paper has been validated with 220.0 kV transmission line and 220.0/66.0 kV power transformer to discusses the actual operating system for control, alarms, status, and measurements. © 2020 School of Science, IHU.
