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...

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 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...
