Solutions toElectrical Utilities - Cases from
IEC TC 57Capetown, South Africa - 2005-10-20

Contents

• Background on TC57
• Overview of Standards developed in TC57
• Focus on Common Information Model (CIM) and its
  use for information exchange between electric
  utility systems
• Focus on 61850 and its use for substation
  automation

4
Background

• TC 57 was established in 1964
• Urgent need to produce international standards in
  the field of communications
• between the equipment and systems for the
  electric power process, including
• telecontrol, teleprotection and all other
  telecommunications to control the electric power
  system.
• TC57 changed its title and scope in 1994 and
  again in 2003
• Need to take into consideration not only
  equipment electrical aspects, but also growing
  need for standardization of information exchange
  between IT systems

5
Title and Scope

• Title Power systems management and associated
  information exchange
• Scope To prepare international standards for
  power systems control equipment and systems
  including
• EMS (Energy Management Systems), SCADA
  (Supervisory Control And Data Acquisition),
  distribution automation, teleprotection, and
  associated information exchange for real-time and
  nonreal-time information, used in the planning,
  operation and maintenance of power systems.
• Power systems management comprises control within
  control centers, substations and individual
  pieces of primary equipment including telecontrol
  and interfaces to equipment, systems and
  databases, which may be outside the scope of TC
  57.

6
Business Environment

• Increasing competition among electric utilities
  due to the deregulation of the energy markets
• Greater need for the integration of equipment and
  systems for supporting the utilitiescore
  processes.
• Former closed energy management systems will be
  opened to be able to use Best of Breed software
  applications and exchange information with
  external systems
• Planning, operation and maintenance of power
  systems
• Business systems of system operators to optimize
  the use of the power system in the energy market
• Equipment and systems have to be interoperable
• How? gt interfaces, protocols and data models
  must be compatible to reach this goal
• Well-proven, international standards in the
  utility business are the key

7
Market Demand

• Customers of the standards developed by TC 57
• Power industry (utilities, energy customers) and
  the vendors of power systems control solutions
• Both parties are actively represented in TC 57
• The standards developed by TC 57 are widely used
  worldwide (e.g. IEC 60870-5 and IEC 60870-6
  TASE.2)
• Increasing demand for recently issued standards
  (e.g. IEC 61970/68 Common Information Model (CIM)
  and IEC 61850)

CIM Provides Vocabulary - CIM XML Provides
Standard Messages

• Websters Dictionary CIM
• Provides standard data semantics and data types
• Sentence structure CIM- based XML messages
• Just as you must have structured sentences to
  communicate orally, you must have standard
  messages to share data electronically
• Standard messages are needed to
• Ensure interoperability both within and between
  utilities
• Remove seams
• Define that part of CIM that must be supported by
  an application
• Adapters provide CIM lt-gt proprietary data
  mappings used by applications

16
CIM Acceptance

• Over 50 utilities, ISOs and NERC
• 60 applications based on CIM
• 30 suppliers sell application/products based on
  CIM
• See CIM Reference List for Details
• Endorsed by other standards organizations
• Foundation for Model-Driven Integration (MDI)
  architecture
• New CIM User Group now formed to deal with
  questions and issues arising from increased use
• Current site www.cimuser.org
