A white paper by the NASPI Distribution Task Team (January 2018). The purpose of this white paper is to provide an introductory reference for industry and academic practitioners interested in exploring the use of synchrophasors and other time-synchronized measurements for supporting power...

Use Case The objective of Phase Identification is to recognize, track and report the connectivity and loading of Phases A,B,C through the distribution system so as to prevent excessive phase imbalance. Background Distribution system maps and models tend to lack reliable information about which...

Use Case Disaggregation of net metered distributed generation (DG) from customer load uses high-precision measurements on the utility side of the meter to estimate the actual generation and amount of load offset behind the meter. Background When the distribution utility lacks access to separate load...

Use Case Synchronized measurements at multiple locations throughout a distribution system during a fault can aid in the location of the fault and expedite service restoration. Background The vast majority of faults originate in distribution systems. The traditional means of locating a fault on a...

Use Case Conventional remote terminal unit (RTU) based automation approaches suffer from slow measurement update and lack of time-stamp values for precise comparison of state parameters at different locations . A time-synchronized control approach is more favorable for protection event analysis...

This report is a summary of work done principally in 2015 and 2016. The work began, at a low level of funding and activity, a year or so earlier, in an attempt to understand what exactly was being measured by a device known as a phasor measurement unit. This was important because I was a member of...

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 paper explores the value that can be added in the near future by using synchrophasor data and applications in the areas of system islanding detection and blackstart restoration. It includes descriptions of: Related functional entity roles and responsibilities Ways that synchrophasor technology...
