US standards body sets sights on phasor data concentrators


US-based Institute of Electrical and Electronics Engineers (IEEE) sets up two new working groups to improve fault management and other smart grid functionality.

The two projects approved by the Standards Association of the IEEE will focus on future standardisation of phasor data concentrators (PDCs).

Bill Ash, strategic technology program director at IEEE-SA, said: “Because PDCs are becoming more common, their functionality requires standardisation.

“This project provides the requirements for what functions PDCs must perform and how it should perform them.”

The creation of the working groups come as the introduction of smart grid functionality drives a need for data aggregation and automated reporting.

As a phasor measurement unit measures electrical waves on a grid, the synchrophasor data is collected using PDC technologies and feed it back to the utility, either on-site or at a centralised location.

Mr Ash said: “An electric utility is measuring the various currents and voltages that are collected by PDCs.

“The future standards from these two projects are intended to help electric utilities with commonality among naming structures, formats and conventions.

“The standards that apply to the smart grid with intelligent electronic devices and many others all require the same naming convention to accurately identify and comprehend the data collected from PDCs.”

Working group IEEE PC37.247 is intended to improve interoperability of devices, systems and applications that use synchrophasors and other synchronized data by standardizing requirements for PDCs.

And the other project IEEE PC37.248 is a guide that provides convention for naming physical and virtual intelligent electronic devices.
