The IEEE Standards Association (IEEE-SA) has approved two new projects to develop future standardization of phasor data concentrators (PDCs): IEEE PC37.247 "Standard for Phasor Data Concentrators for Power Systems" and IEEE PC37.248 "Guide for Common Format for Naming Intelligent Electronic Devices." Both development projects, IEEE notes, are designed to produce standards that help improve fault management and other smart grid functionality.

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, IEEE says. Because this standard specifies the requirements of PDCs for power systems, it handles data aggregation, processing of synchrophasors and other synchronized data, commands, performance, and testing.

According to the organization, IEEE PC37.248 is a guide that provides convention for naming physical and virtual intelligent electronic devices (IEDs). The guide is intended to provide consistency to the point that automated systems and persons unfamiliar with the particular electrical system could determine what entities the IEDs are monitoring or reporting. In addition, the guide provides a common convention for naming physical and virtual IEDs and discusses the various environments where device names are needed and how a common naming convention would be beneficial.

"Having standards in place to assist with locating faults on an electric grid is vital to the industry's forward progress," comments Bill Ash, strategic technology program director with IEEE-SA. "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," he adds.

"For several years, synchrophasor data has existed on a small scale or as a first project. But in the last few years, more and more synchrophasor systems are getting installed," says Vasudev Gharpure, chair of the IEEE Phasor Data Concentrators for Power Systems Working Group. "Because PDCs are becoming more common, their functionality requires standardization. This project provides the requirements for what functions PDCs must perform and how it should perform them, which is the purpose of our working group."
