Deployment of smart substation standard IEC 61850

To fully benefit from the value offered by IEC 61850 the standard has to be applied in a context where all aspects are considered. Vattenfall Distribution Nordic therefore initiated a project to define and prepare the implementation of internal processes for deploying IEC 61850 as the primary enabler for smart substations, and to compile a strategy for substation projects. The outcome includes several parts; a process description and implementation of deployment of IEC 61850, a review of tools and other work environment devices for the complete life-cycle, definition of standard functions that a smart substation shall include and definition of interfaces to Vattenfall system architecture. The results have been incorporated in an updated technical guideline and in a specification of a substation automation project. The next phase includes a test of the new strategy and processes using state-of-the-art IEC 61850 solutions in a pilot installation in Upplands Väsby 70/20 kV substation in Stockholm to verify the results in close corporation with the SAS supplier. As results from full deployment of IEC 61850 this paper gives an overview of how IEC 61850 affects different aspects of substation automation projects and how the evaluation of this pilot project including novel protection and control functionality is conducted.
