The BIG Picture - Open Source Software (OSS) for Disturbance Analytic Systems

1,043 views

Published on

A comprehensive look at building automated systems for electric power system disturbance analytics using open source software(OSS). This presentation covers the value of OSS for electric utility data systems, some existing OSS components, and gaps remaining for true end-to-end solutions. The existing OSS components and business processes discussed have been used to successfully deploy automated fault location systems at some of the largest utilities in the US. Additional opportunities exist for the creation of OSS solutions for intelligent electronic device (IED) data retrieval and remote device management. The transparency of OSS and the community that surrounds and supports it, facilitate the collaboration needed for rapidly evolving software solutions to enable a smarter grid, and facilitate continuous grid modernization.
