“…The fiber cable is considered as a very high data transmission rate. The acceleration facility is contributing to isolate the line instantaneously at the fault happen in the transmission line [52][53]. This facility important at the line fault near one side which the remote IED protection relay calculate the fault impedance in the zone two boundaries, which will send the trip order after 200 ms to 500 ms delay time.…”

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.
“…During the inverse time delay, higher currents lead to shorter trip times, while lower currents lead to longer trip times. These relays receive input from the CT that is able to sample the current from the main line as well as transmitting it to the relay for analysis and operation [ 16 ]. Fig.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
