Inter and Intra Substation Communications: Requriements and Solutions

摘要

As the substation communication world searches for the "Promised LAN", it would be helpful to have a roadmap to give direction to the search. Many are the expectations of a LAN flowing with data and able to connect with any Intelligent Electronic Device (IEF) that was ever made. Such expectations must be tempered with the cost and complexity of achieving them. This paper presents an outline of the communicatio requirements of the myriad of IED's in existence in the substation today as well as the expectations of what second generation microprocessor based devices might be able to do. Requirements will focus on language issues, system capabilities, performance requirement,s external interfaces, environmental, and quality issues. Some attention will also be given to the architecture of a solution and some guidelines as to how this structure might be built.
