IEEE announces five new standards for the smart grid – March 2012
By Alyssa Dalton
April 10, 2012 – IEEE has introduced five new standards, as well as a modified standards-development project, to aid with the worldwide rollout of the smart grid. The newly-published standards include:
• IEEE C37.118.1-2011 – Standard for Synchrophasor Measurements for Power Systems – intended to define synchronized phasors and frequency measurements in substations, along with methods and requirements for verifying such measurements in power system analysis and operations under both static and dynamic conditions.
• IEEE C37.118.2-2011 – Standard for Synchrophasor Data Transfer for Power Systems – intended to specify a method (including messaging types, use, contents and data formats) for real-time communications among phasor measurement units (PMUs), phasor data concentrators (PDCs) and other power-system applications.
• IEEE C37.238-2011 – Standard Profile for Use of IEEE Std. 1588 Precision Time Protocol in Power System Applications – designed to provide precise time synchronization within and among substations across wide geographic areas via Ethernet communications networks.
• IEEE C37.232-2011 – Standard for Common Format for Naming Time Sequence Data Files (COMNAME) – designed to define the naming of time sequence data (TSD) files that originate from digital-protection and -measurement devices.
• IEEE 1020-2011 – Guide for Control of Small (100 kVA to 5 MVA) Hydroelectric Power Plants – updates an existing IEEE standard to address significant technology changes impacting small hydro-plant control issues and monitoring requirements that have emerged since the guide’s original publication.
Additionally, IEEE Standards Association (IEEE-SA) has modified the scope and purpose of an existing standards-development project related to the smart grid: IEEE P1409 – Draft Guide for the Application of Power Electronics for Power Quality Improvement on Distribution Systems Rated 1 kV Through 38 kV.
