Working Groups

WGNameChairVice ChairScope
K1PC 37.245 Guide for the Application of Protective Relaying for Phase Shifting TransformersLubomir SevovBrandon DaviesTo write a guide for the application of Protective Relaying for Phase Shifting Transformers (PSTs). The protection methods for different types of PST and operating conditions of PSTs will be reviewed. Representation of PST models to determine short circuit currents for relaying considerations will be considered. Protection CT sizing and location issues will be considered. Relay application and setting examples will be provided.
K10SCC21 Distributed Resources Standard CoordinationBen KazimierMark SiiraTo interface with SCC21/P1547 in order to reduce unnecessary delays by getting PSRC input into the process without having to wait for after-the-fact coordination.
K11Open Phase Detection for Nuclear Generating StationsCharlie SufanaMichael UrbinaWrite a report to the K Subcommittee entitled Methods for Analyzing and Detecting an Open Phase Condition of a Power Circuit to a Nuclear Plant Station Service or Startup Transformer.
K12P1032 Guide for Protecting Transmission Static Var CompensatorsSatish SamineniMartin BestTo work jointly with Substations WG I9 to write a guide for protecting transmission static var compensators. PSRC WG K12 will provide guidance and review on topics that are already covered in other IEEE guides to prevent overlap and identify areas where interpretation of existing guides is necessary to meet the specific application challenges unique to transmissions static var compensators.
K13PC37.116 IEEE Guide for Protective Relay Application to Transmission-Line Series Capacitor BanksIlia VolohLuis PolancoRevise IEEE C37.116 “Guide for Protective Relay Application to Transmission-Line Series Capacitor Banks”.
K16PC37.91 Revision of IEEE Guide for Protecting Power TransformersWill EnglishSteve ConradTo revise and update C37.91, IEEE Guide for Protecting Power Transformers to correct errors and address additional protection related topics.
K17Geomagnetic Disturbances (GMD)Qun QiuLuis PolancoTo submit a WG report to the PSRC K Substation Subcommittee evaluating the performance of protection systems during Geomagnetic Disturbances.
K18PC37.108, Guide for Protection of Secondary Network SystemsAdi MulawarmanSurarat PavavicharnTo revise and update C37.108-2002 –Guide for the Protection of Secondary Network Systems.
K19Advisory to IEC 60255 -187-1 Functional Requirement for Restrained and Unrestrained Differential Protection of Motors, Generators and TransformersGustavo BrunelloAbu BaparyTo provide an advisory function to the IEC working group.
K21C37.112 Standard Inverse-Time Characteristic Equations for Overcurrent RelaysRandy CrellinMichael ThompsonTo pursue the renewal of C37.112.
K22C37.234 IEEE Guide for Protective Relay Applications to Power System BusesAbu BaparyMichael ThompsonRevise and ballot IEEE Standard C37.234 prior to its expiration in 2019.
K23Summary Paper for C37.119 IEEE Guide for Breaker Failure Protection of Power Circuit BreakersRoger WhittakerAdi MulawarmanTo make and present at regional conferences, a summary paper of C37.119-2016 – IEEE Guide for Breaker Failure Protection of Power Circuit Breakers.
