IEC TC57 WG14

• Developing IEC 61968
• Focus is to describe the information exchanges
  between systems (i.e. A2A and B2B) related to
  distribution operations
• Defines integration between a variety of systems
  including network management, outage management,
  work management, asset management, SCADA,
  metering, call handling,
• IEC 61968-1 architecture specification is
  transport independent
• XML used to format message payloads
• Messages defined using nouns and verbs
• Recognizes request/reply and publish/subscribe
  messaging paradigms

IEC 61968

• Extends the 61968 package of the CIM, where the
  core CIM is defined by IEC 61970-301
• Integration defined using XML messages
• Messages have a header and a payload
• Header identifies a noun and a verb
• Payload uses CIM-derived type definitions as
  described using XML Schema
• Can be used for SOA implementations

CIM Extensions

• Modeling of electrical distribution, extending
  Wires package
• Added 61968 package to CIM
• Assets
• Consumer
• Documentation
• Work
• ERP_Support (leverages OAG)

IEC 61968 Messages

• Message has header, with optional request, reply
  and payload sections
• Header includes information such as a verb, noun,

• GET
• SHOW
• REPLY

• Publish/Subscribe
• CREATED
• CHANGED (UPDATED)
• CANCELED

12
Example Message Nouns

• NetworkDataSet
• NetworkChangeSet
• LoadDataSet
• OperationalRestriction
• SafetyDocument
• SwitchingSchedule
• OutageReport

• TroubleTicket
• PlannedOutage
• OutageNotice
• Work
• Schedule
• AcessPermit
• OneCallRequest

13
Steps in Defining Messages

• Generate XML Schema complex types from the CIM
  (once)
• Develop use cases
• For each use case, identify message sequences in
  terms of verbs and nouns
• For each message define XML Schema, identifying
  necessary payload content in terms of references
  to CIM complex types

Status

• Last meeting held October 2005 in St. Louis,
  attended by 19 persons
• Next meeting to be held January 2006 in
  Switzerland
• Parts 1 and 3 have been completed, but will be
  updated to reflect agreed use of XML Schema
• Most work is currently being done on parts 4, 6,
  9 and 12
• Need to get WG14 CIM changes stabilized into base
  CIM
