چکیده
During the last years utilities have been facing a strong trend towards new technologies and standards. The most significant task is to fundamentally transform the capabilities and bring new solutions that support better power quality supply. Standardization solution IEC 61850 in terms of protection, monitoring and control functions is a promising solution that provides a great impact on substation automation based on increasing the reliability and availability of the electric power grid. Communication in substation based on the IEC61850 standard that specifies Ethernet network for substation automation which provides an efficient performance. This efficiency has been introduced by means of high flexibility of configuring various architectures based on implementing Ethernet switches. This paper investigates the reliability and availability for substation protection function based on Reliability Block Diagram (RBD) approach for practical substation architecture (T1-1) in different configuration. Keywords-Relaibility, Availability, IEC61850, SAS, BFP, IEDs, Distributed functions. Protection and control functions.
