Across Dominion Energy's T&D footprint, the frequent addition of new equipment and retirement of old ones make it challenging to manually manage PI tags and AF models. We aim to automate the creation and updating of the AVEVA PI System, which contains over 5 million tags, by integrating data from both EMS and ADMS SCADA systems. The goal is to maintain AF models with a user-friendly structure that consolidates relevant information from various systems.
