Development of TVA SuperPDC: Phasor applications, tools, and event replay

With information and measurement technology evolving rapidly within the electric power industry, wide-area measurement, monitoring and control (WAMC) is deemed to be the key technology to improve power system reliability. Guided by this vision, the North American SynchroPhasor Initiative (NASPI) is a nation-wide project that collaborate various resources to build the infrastructure of WAMC across North American. As part of NASPI, Tennessee Valley Authority (TVA) is developing Super Phasor Data Concentrator (SuperPDC) which is the infrastructure hosting different measurement resources and providing platform for numerous WAMC applications, both real-time and none real-time. This paper outlines the SuperPDC architecture and demonstrates some real-time and close to real-time applications, developed by TVA and Virginia Tech based on SupersPDC platform.
