Abstract: A variety of work architectures offering different levels of performance. cost and redundancy are achievable using managed switches. With constructing of the Smart Substation, the using work quickly ing more and more important. This article looks at considerations when designing an work for substation automation applications which may include IEC61850 Station or Process bus or bination of both, with focus on redundancy. By analysis the two sides of defferent architectures, understanding the relationships between the physical strcuture of work and the protocols than run on work is key to creating s truly maintainable and work that deals with issues effectively.
