New Technical Standard For Synchrophasors Adopted By IEC

The North American Electric Reliability Corp. (NERC) and the North American SynchroPhasor Initiative (NASPI) have expressed support for the International Electrotechnical Commission's (IEC's) recent adoption of a technical standard that establishes improved synchrophasor data communication.

The approval of technical interoperability standards is an important milestone marking the maturity of synchrophasor technology and systems, NERC says, adding that industry consensus allows manufacturers to standardize their offerings.

"Adoption of this IEC standard supports the integration of synchrophasor technology into day-to-day grid operations," says Mark Lauby, vice president and director of reliability assessment and performance analysis at NERC.
IEC 61850-90-5 is one of several technical interoperability standards adopted to advance smart grid technology. The new standard addresses delivery of high-speed data collected by synchronized phasor measurement devices over wide-area communications networks.

The U.S. Department of Energy is working with the National Institute of Standards and Technology (NIST) to accelerate the development of key smart grid interoperability standards, including IEC 61850-90-5. NASPI's Performance and Standards Task Team, working with NIST, continues to develop standards and guidelines for phasor measurement units, phasor data concentrators, GPS time-stamping of phasor data and related synchrophasor technology elements.

More than 65 transmission owners and operators across North America have deployed synchrophasor systems to monitor transmission grid conditions and improve grid operations.
