The Grid Protection Alliance (GPA) is a not-for-profit corporation formed to facilitate and support the development and deployment of comprehensive electric energy system-wide solutions and enhancements to electric sector security through integrated, adaptable, collaborative and rapidly-evolving programs of threat identification and analysis and infrastructure research, development, demonstration and technology transfer. GPA focuses on improvements to electric energy resiliency and maintenance of reliability and availability. The efforts will accommodate the evolving technology of electric energy systems including Smart Grid development and deployment, advanced generations sources and enhanced systems integration.
Grid Solutions
|
The Grid Solutions Division of GPA develops open source software applications to meet the specific demands of real-time data collection and storage to support electric grid operations and planning. GPA products are hosted in the CodePlex open source project community provided by Microsoft. GPA maintains product documentation and code at the code plex project locations shown to the right of each GPA product title below. GPA's current product focus is on synchrophasor applications. Synchrophasors are GPS time-stamped measurements taken rapidly (at least 30 times per second) from different points on the power grid. These measurements are transmitted in real-time to operations centers where they provide information on the state and health of the power system. Synchrophasor information can be used to monitor power flows on the electric grid and to identify areas or conditions where problems exist. Learn more about synchrophasors from a recent NERC report, “Real-Time Application of Synchrophasors for Improving Reliability.” PMU Connection Tester – http://pmuconnectiontester.codeplex.com/ to download executables and source code. GPA's PMU Connection Tester can be used to verify data streaming from devices that transmit synchrophasor data in the following phasor data procols: IEEE C37.118 R1, IEEE 1344, BPA PDCstream, SEL Fast Message, FNET streaming data protocol and Macrodyne (Type M) openPDC – Phasor Data Concentrator - http://openpdc.codeplex.com/ to download executables and source code. A phasor data concentrator collects phasor data from hundreds of measurement units installed on power transmission lines, aligns the data by GPS time-tag, and creates a single time-synchronized dataset that is forwarded on to other software applications. See: openPDC Overview. openHistorian 2.0
– Time-Series Data Archive -
http://openhistorian.codeplex.com/ A historian, like the openHistorian, is a software application that is optimized to store large volumes of time-stamped operational data quickly and efficiently. The openHistorian 1.0 is included with the openPDC and openPG and can be used to store measurement data. The openHistorian 2.0 is being redesigned from the ground up to support the full range of data types with larger and more precise timestamps. The openHistorian 2.0 will also include lossless compression that can significantly reduce physical storage requirements. The openHistorian will be improved and expanded through an APRA-E grant, Robust Adaptive Topology Control. Texas A&M is the prime receipient for this award. openPG – Phasor Data Gateway - http://openpg.codeplex.com/ to download documentation, executables and source code. For an overview of the approach for openPG configuration, see the presentation on openPG Manager Screens. Phasor Gateways are needed to securely and efficiently exchange phasor data among utility grid operating entities. The production version of the openPG (Version 1.0) was released in March 2012 and is currently undergoing demonstration and rigerous testing. See: The business case for using phasor gateways. SIEGate – Secure Information
Exchange Gateway for Electric Grid Operations GPA is the prime contractor on a U.S. Department of Energy (DOE) project to develop a secure exchange information gateway (SIEGate) for the bulk electric system. Partners in this effort include the University of Illinois at Urbana-Champaign, Pacific Northwest National Labs, Alstom-Grid and the PJM Interconnection. The SIEGate project is part of DOE’s Cybersecurity for Energy Delivery Systems (CEDS) Program that is under DOE’s Office of Electricity Delivery & Energy Reliability. See: SIEGate Overview. GPA products are built on two foundational C# libraries hosted as CodePlex projects -- (1) GPA's Time Series Framework (http://timeseriesframework.codeplex.com/), and (2) the TVA (Tennessee Valley Authority) Code library (http://tvacodelibrary.codeplex.com/). Both projects consist of hundreds of class libraries that extend and expand the functionality included in the .NET Framework. GPA is a major contributor to the TVA Code Library and is among its project coordinators.

GPA User's Forum - August 21-22, 2012
|
The Inaugural GPA User's Forum was held in Altanta on September 6-7, 2011. The Second Annual GPA User's Forum is scheduled for August 21 and 22, 2012 and will be hosted at NERC's Atlanta Office in Buckhead. The first day of the GPA User's Forum will be a deep dive into GPA open source libraries and products and is intended for C# developers looking to deploy and/or enhance them. Day 2 will be a series of presentations from GPA product users and developers. The 2012 User's Forum will focus on phasor gateways and the "Gateway Exchange (publish/subscribe) Protocol" (GEP) and the openPDC Version 1.5 which is targeted for release in the Summer of 2012. Please contact us if you would like more informaiton on registration for this event.
