Relaying Communications Subcommittee


Evaluate and report on the characteristics and performance of protective relaying communications and control systems. Recommend communication requirements, operating and test procedures which assure reliable performance of the overall protection and control system. Report on new relaying equipment designs tailored to specific communication requirements. Included are matters necessary to the function of such systems employed in the generation, transmission, distribution, and utilization of electrical energy, and their effects on system operation. Control systems include data acquisition and processing from devices such as transducers, Intelligent Electronic Devices (IEDs), and Human Machine Interfaces (HMIs) including the low-level interfaces to these systems. Power System control issues associated with Power System Dynamics are excluded from this scope.

Working Groups

WGNameChairVice ChairScope
H3Time Tagging for Intelligent Electronic Devices (COMTAG)Bill DickersonJim HackettDevelop an IEEE Standard for time tagging for power system IEDs. This will include common requirements for time tags, and show how to apply them to various classes of time sequence data. Requirements and methods for stating the resulting time accuracy will be included.

H11IEC/IEEE 60255-118-1, Synchrophasor for Power Systems – MeasurementsKenneth MartinAllen GoldsteinDevelop a joint IEC/IEEE standard for synchrophasor measurements based on the IEEE Stds. C37.118.1-2011 and C37.118.1a-2014 according to the PAR issued June 2013.
H17Establishing Links between COMTRADE, IEC 61850 and CIMChristoph BrunnerAlex ApostolovDevelop a standards approach to link IEC 61850, CIM and COMTRADE so that the COMTRADE channels can be associated to a node in the power network.
H22PC37.249 Guide for Categorizing Security Needs for Protection Related Data Files (Joint Working Group Substations Committee C19 & PSRC H22)Amir MakkiCesar CalixIdentify and categorize protection related data files based on content, use, and risk of disclosure or compromise. Protection related data files include but are not limited to files used for configuration, management, and analysis of protective relaying systems.
H23Guide for Naming Intelligent Electronic Devices (COMDEV)Rick CornelisonEric AllenDevelop an IEEE Guide for naming Intelligent Electronic Devices (IEDs) based on the report of Working Group 10.
H27Standard File Format for IED Configuration Data (COMSET)Chris ChelmeckiBharadwaj VasudevanDevelop a standard XML based file format for exchange of protection and control configuration data between engineering tools and asset management tools. The modeling and naming conventions should be based on the definitions and extension rules defined in IEC 61850.
H30IEC 61850 User FeedbackDeepak MaragalCollect user feedback from utilities and consultants for designing and implementing IEC-61850 based substation automation system. Prepare a report outlining the experienced issues and suggest enhancements to IEC-61850 standard and manufacturer implementations.
H31Common Protection & Control Parameters for COMSETDeepak MaragalAlex ApostolovDevelop generic models and parameters of protection functions.
H32Performance Requirements for Ethernet Circuits Applied to TeleprotectionKen FoderoWalter McCannonDevelop a report on the use of Ethernet transport for teleprotection services and line current differential protection. This report will define the channel performance requirements for Ethernet transport systems / circuits that carry pilot protection communications.
H35XML Translation for COMTRADEMark AdamiakCreate a report with recommendations and implementation guidelines for the update of COMTRADE - specifically with the inclusion of XML definitions of the Configuration, Header, and Data areas.
H38Design and Implementation of Time Synchronization Distribution Systems for Substation Automation (P2030.101)James BougieThis guide practice covers the design, installation and monitoring of time synchronization systems in power utility substations. This includes time sources such as Global Positioning Satellite (GPS) and time distribution systems such as Inter-Range Instrumentation Group -B (IRIG-B), Network Time Protocol /Simple Network Time Protocol SNTP (NTP/SNTP), and Standard Profile for Use of IEEE Std. 1588 Precision Time Protocol in Power System Applications - IEEE STD.
H40Databases used in SASJames BougieThis recommended practice presents general requirements, design, and lifecycle costs versus performance for databases associated with substation automation systems. Also included are specifications for database elements that should be standardized to ensure interoperability. Example designs are included for reference purposes, which are not intended to prescribe a definitive database design. Applications utilizing databases can be very different and may have vastly different requirements.
H41Revision of IEEE 1646 Communication Delivery Time Performance RequirementsCraig PreussRevise IEEE standard 1646-2004 – IEEE Standard Communication Delivery Time Performance Requirements for Electric Power Substation Automation".
H44Enhancing GOOSE I/O MonitoringAaron MartinDetermine if a working group should be formed to assess enhancing GOOSE I/O monitoring.
H45Guide for Centralized Protection and Control (CPC) Systems within a SubstationRatan DasExplore the possibility of a Working Group to develop a “Guide for Centralized Protection and Control (CPC) Systems within a Substation”.
