NASPI Tracking Number: NASPI-2024-TR-001

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...

TRS and PNNL collaborated to develop a Use of Time-Synchronized Measurements in the Real-time Ops Horizon training course (8 CEH). Course Summary: Provide an introduction to synchrophasor technology, describe the value it can provide in the Real-time Ops Horizon, and demonstrate how synchrophasor...

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).

Data mining is the process of turning raw data into useful information. Data mining has been employed in many different data-rich industries, including banking, healthcare, manufacturing, and telecommunications. With the additions of thousands of PMUs to the nation’s power grid, the power systems...

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...

An ATC Operations Engineer was using synchrophasor data to review fault operations and stumbled across the odd voltage signature shown below from a PMU monitoring one of our 69 Kv substations. One of the three voltage phases would “drift” away from the other two phase voltages and then eventually...
