The North American SynchroPhasor Initiative's (NASPI's) mission is to improve power systems reliability and visibility through wide-area measurement and control by fostering the use and capabilities of synchrophasor technology. This report is prepared by the Data & Network Management Task Team...

This paper describes how synchrophasor technology can be used in the Real-time Operations Horizon to determine the origin, nature and severity of disturbances on the electric power system. Specifically, this paper considers how synchrophasor data and their application can be used by System...

Effort being led by Jeffrey Taft (PNNL).

Phasor measurement units (PMUs) are becoming prevalent on the power system, as is their integration into advanced power system applications. Performance characteristics for the PMU devices are formalized under IEEE Standard C37.118.1-2011 [1]. Formalizing the data requirements for PMU-based...

In 2007-09, DOE worked with NASPI to fund the development of an architecture framework for synchrophasor data networks. That “NASPInet” framework has been the prevailing guidance since that time, and various NASPInet elements were incorporated and tested in several of the SGIG synchrophasor projects...

This paper describes certain functional entity roles and responsibilities related to oscillation detection monitoring, considers how synchrophasor technology may be used to identify actual oscillation events or issues, and describes some of the related commercial applications that are currently...

Compliance with the NERC requirements for Critical Infrastructure Protection (CIP) for synchrophasor systems in the Version 5 paradigm seems to be a matter of some uncertainty for those in the synchrophasor user community. In the words of the Edison Electric Institute, an organization that...

This paper addresses how synchrophasor technology can be used for phase angle monitoring and describes the various synchrophasor-based applications being used by electric utilities and grid operators presently. Uses for phase angle monitoring include: • Wide-area situational awareness and...

This paper describes certain functional entity roles and responsibilities related to voltage stability monitoring, considers how synchrophasor technology may be used to identify actual or potential voltage stability issues, and describes some of the related commercial applications that are currently...

This report describes a fall 2014 survey of the design and deployment of the synchrophasor data networks used by some of the operational entities of the North American electric power industry. This survey was focused on wide-area networking for real-time streaming of measurement data collected by...
