This technical report reviews the state-of-the-art in composite system reliability (CSR) evaluation. Reliability assessment methods for composite generation and transmission systems have been developed in recent decades.

This paper introduces a framework for comprehensive testing and evaluation of the phasor measurement units (PMUs) and synchrophasor systems under normal power system operating conditions, as well as during disturbances such as faults. The evaluation is suggested to be accomplished using three different testing approaches, namely, type testing, application testing, and end-to-end testing, for each of which, systematic characterization of the hardware and software modules is presented in detail.

This paper documents and shares information about the practices of electric utilities in the design of protective relay tripping circuits and associated control and protective functions. This information has not been widely disseminated before and the Working Group hopes that its publication may help to encourage uniformity as well as help others avoid the snares and pitfalls which have been found through hard experience.

This report proposes a test that can be applied to any type of transmission line distance relay to ascertain its response to off-nominal frequency and abnormal system voltages.

This report provides recommendations to the J Subcommittee on coordination issues and other relevant matters gleaned from the NERC Technical Reference Document and the review of the relevant IEEE Guides to be used as feeder material and technical additions for consideration in the next revisions of IEEE C37.91, C37.96, C37.101, C37.102, and C37.106. It also provides comments to NERC for possible revisions to the Technical Reference Document.

This paper will primarily address the subject of reducing outages / durations and autorestoration applications within the distribution substation.

This report discusses the uses of AC transmission line modeling used for relaying. The report also covers the important issues and problems that affect the model parameters and discusses the various methodologies for validating the accuracy of the model.

This report discusses the justifications and application criteria for applying directional overcurrent relays for ground fault detection as applied for protection of transmission lines. Polarization topics, pilot scheme setting practices, and resonance grounding issues are not addressed.

This IEEE Technical Report entitled “Studies for Planning HVDC” prepared by the Transmission & Distribution Committee, HVDC & FACTS Subcommittee, Working Group 15.05.18 gives an overview of general steps/studies which are necessary during an HVDC project. They are structured in
