23、 be exchanged within and external to substation integrated protection, control, and data acquisition systems. Purpose Utilities will use communication performance requirements as part of a procurement specification to develop new substation automation systems, or to modify existing substation automa

24、tion systems. Vendors will use communication performance requirements to build open system communication interfaces for intelligent electronic devices for substation automation. IEEE 1646 is communication protocol and data model neutral IEEE 1646 is a specification of communication delivery time per

25、formance requirements, other than for time synching; it does not specify an underlying protocol nor does it specify the data model used to exchange information. End users must consider the bandwidth available for communication within an electric power substation, between substations, and between sub

26、stations and other entities. End users must also select a comprehensive data model describing the semantics of the information to be exchanged. Document organization In addition to the overview, described in this clause, normative references are described in Clause 2 and definitions, acronyms and ab

27、breviations are defined in Clause 3. Communication delivery time performance requirements are described in Clause 4 to specify the measurable criteria for complying with this standard. Clause 5 and Clause 6 describe the communication capabilities and system capabilities required to deliver data with

28、in specified times. Copyright 2005 IEEE.
