Archiving Energy Utility Transmission Synchrophasor Data in the PI System with custom AF at PG&E
Power and Electric Utilities

PG&E has had a comprehensive Phasor Measurement Unit deployment since 2010. The Synchrophasor data being collected was only available on the operations network. This meant that only a few people were able to access the data and the tool set for data access was limited. PG&E recently completed a two-year project to publish the synchrophasor data from the operations network to the corporate network and archive the data in a PI Collective. The presentation will cover the architectural issues encountered with security concerns and data redundancy. The presentation will also cover naming conventions and how the relate to an automated AF builder utility developed for the project. The presentation will also discuss some data use cases and compression settings
