Relaying Communications and Control 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.

H6IEC 61850 Application TestingCharlie SufanaBenton VandiverWrite a report to the H Subcommittee on application testing of IEC-61850 based protection and control systems. Emphasis will be on the GOOSE functions.
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.
H27Standard File Format for IED Configuration Data (COMSET)Mario CapuozzoBenton VandiverDevelop 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 MaragalAaron MartinCollect 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.
H40Databases used in SASTheo LaughnerMario CapuozzoThis 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 RequirementsD. HolsteinT.W. CeaseRevise IEEE standard 1646-2004 – IEEE Standard Communication Delivery Time Performance Requirements for Electric Power Substation Automation".
H44Enhancing GOOSE I/O MonitoringAaron MartinRalph MackiewiczDetermine if a working group should be formed to assess enhancing GOOSE I/O monitoring.
H45C37.300 Guide for Centralized Protection and Control (CPC) Systems within a SubstationRatan DasP. MyrdaExplore the possibility of a Working Group to develop a “Guide for Centralized Protection and Control (CPC) Systems within a Substation”.
H46Recommended Practice for Human-Machine Interfaces (HMI) used in Substation Automation Systems (PC37.1.3)Matt BlackCraig PreussProduce a Recommended Practice for Human-Machine Interfaces (HMI) used in Substation Automation Systems.
H47Impacts of IEC 61850 sampled values, GOOSE and PTP time synchronization on protection and control applications using process busM. KanabarA. RiccardoIn a digital substation Protection and Control (P&C) devices rely on Sampled Values (SV), GOOSE and time synchronization (PTP) together over process bus to communicate with Merging Units (MUs). This Working Group will generate a report evaluating the discrepancies in the communication of SV, GOOSE or PTP messages and their impact on protection and control applications such as performance and behavior.
H49Application Considerations on the Use of Packet-Switched Communication Channels for Pilot Protection and Teleprotection SchemesG. StoedterL. ErichsenDevelop a report/tutorial on switched networks from a pilot protection application point of view for the benefit of relay engineers.
H50Requirements for Time Sources in Protection and Control SystemsD. OuelletteJ. AndersonTo produce a Report on Requirements for Time Sources in Protection and Control Systems.
H51IEEE Standard for Common Format for Event Data Exchange (COMFEDE) for Power SystemsM. AdmiakPierre MartinReview the existing standard and determine whether a revision of the COMFEDE standard (C37.239-2010) is needed.
H52Common Format for Naming Time Sequence Data Files (IEEE Standard C37.232-2011, COMNAME)Amir MakkiRevise the Standard. The revision to include clarification on methods of use such as use for naming folders and allowing for underscore delimiters.
