A method for real-time exchange of synchronized phasor measurement data between power system equipment is defined. This standard specifies messaging that can be used with any suitable communication protocol for real-time communication between phasor measurement units (PMU), phasor data concentrators (PDC), and other applications. It defines message types, contents, and use. Data types and formats are specified. A typical measurement system is described. Communication options and requirements are described in annexes.

Synchronized phasor (synchrophasor) measurements for power systems are presented. This standard defines synchrophasors, frequency, and rate of change of frequency (ROCOF) measurement under all operating conditions. It specifies methods for evaluating these measurements and requirements for compliance with the standard under both steady-state and dynamic conditions. Time tag and synchronization requirements are included. Performance requirements are confirmed with a reference model, provided in detail. This document defines a phasor measurement unit (PMU), which can be a stand-alone physical unit or a functional unit within another physical unit. This standard does not specify hardware, software, or a method for computing phasors, frequency, or ROCOF.

ISO/IEC/IEEE 15289:2011 provides requirements for identifying and planning the specific information items (information products, documentation) to be developed and revised during systems and software life cycles and service processes. It specifies the purpose and content of all identified systems and software data records and life cycle information items, as well as records and information items for information technology service management. The information item contents are defined according to generic document types (description, plan, policy, procedure, report, request, and specification) and the specific purpose of the document. For simplicity of reference, each information item is described as if it were published as a separate document. However, information items may be unpublished but available in a repository for reference, divided into separate documents or volumes, or combined with other information items into one document. ISO/IEC/IEEE 15289:2011 is based on the life cycle processes specified in ISO/IEC 12207:2008 (IEEE Std 12207-2008) and ISO/IEC 15288:2008 (IEEE Std 15288-2008), and the service management processes specified in ISO/IEC 20000-1:2005 and ISO/IEC 20000-2:2005.

ISO/IEC/IEEE 26512:2011 was developed to assist users of ISO/IEC 15288:2008 (IEEE Std 15288-2008) or ISO/IEC 12207:2008 (IEEE Std 12207-2008) to acquire or supply software user documentation as part of the software life cycle processes. It defines the documentation process from the acquirer's standpoint and the supplier's standpoint. ISO/IEC/IEEE 26512:2011 covers the requirements for information items used in the acquisition of user documentation products: the Acquisition Plan, Document Specification, Statement of Work, Request for Proposals, and the proposal. It provides an overview of the software user documentation and information management processes which may require acquisition and supply of software user documentation products and services. It addresses the preparation of requirements for software user documentation. These requirements are central to the user documentation specification and Statement of Work. It includes requirements for primary document outputs of the acquisition and supply process: the Request for Proposal and the Proposal for user documentation products and services. It also discusses the use of a Documentation Management Plan and a Document Plan as they arise in the acquisition and supply processes. ISO/IEC/IEEE 26512:2011 is independent of the software tools that may be used to produce documentation, and applies to both printed documentation and on-screen documentation. Much of its guidance is applicable to user documentation for systems including hardware as well as software.

Within the context of the ISO/IEEE 11073 family of standards for device communication, a normative definition of the communication between personal basic electrocardiograph (ECG) devices and managers (e.g., cell phones, personal computers, personal health appliances, and set top boxes) in a manner that enables plug-and-play interoperability is established in this standard. Appropriate portions of existing standards including ISO/IEEE 11073 terminology and IEEE 11073-20601 information models are leveraged. The use of specific term codes, formats, and behaviors in telehealth environments restricting optionality in base frameworks in favor of interoperability is specified. A common core of communication functionality for personal telehealth basic ECG (1- to 3-lead ECG) devices is defined. Monitoring ECG devices are distinguished from diagnostic ECG equipment with respect to including support for wearable ECG devices, limiting the number of leads supported by the equipment to three, and not requiring the capability of annotating or analyzing the detected electrical activity to determine known cardiac phenomena. This standard is consistent with the base framework and allows multifunction implementations by following multiple device specializations (e.g., ECG and respiration rate).

A standard procedure for naming time sequence data (TSD) files, such as files produced by digital fault recorders, power swing recorders, power quality monitors, and so on, is specified. The sources of TSD files are described, and a survey of current naming techniques is provided. The advantages of using a common naming procedure are highlighted, and the limitations and applications are identified. Issues of compatibility across operating systems and various vintages, and adaptability to other types of files, are also discussed. The required and optional portions of the naming procedure are described in detail, and many examples are provided.

Procedures and calculations necessary to apply the standard transient recovery voltage (TRV) ratings for ac high-voltage circuit breakers rated above 1000 V are covered in this application guide. The breaking capability limits of these circuit breakers are determined to a great degree by the TRV. The TRV ratings are compared with typical system TRV duties. Examples of TRV calculation are given with suggested options if the TRV duty exceeds the TRV ratings of the circuit breaker.

This amendment to IEEE Std 802.1Q-2011 specifies protocols, procedures, and managed objects that enable flow control per traffic class on IEEE 802(R) point-to-point full duplex links. This is achieved by a mechanism similar to IEEE 802.3 Annex 31B PAUSE, but operating on individual priorities.
