IEC 61968-11:2013

Application integration at electric utilities - System interfaces for distribution management - Part 11: Common information model (CIM) extensions for distribution

IEC 61968-11:2013 specifies the distribution extensions of the common information model (CIM) specified in IEC 61970-301. It defines a standard set of extensions of common information model (CIM), which support message definitions in IEC 61968-3 to IEC 61968-9, IEC 61968-13 and IEC 61968-14. The scope of this standard is the information model that extends the base CIM for the needs of distribution networks, as well as for integration with enterprise-wide information systems typically used within electrical utilities. Major changes with respect to the first edition are summarized below:
- Introduction of new classes to support flexible naming of identified objects.
- Introduction of new classes to support single line diagrams exchange.
- Consolidated transmission and distribution models for lines, transformers, switching, sensing and other auxiliary equipment.

Intégration d'applications pour les services électriques - Interfaces système pour la gestion de distribution - Partie 11: Extensions du modèle d'information commun (CIM) pour la distribution

La CEI 61968-11:2013 spécifie les extensions pour la distribution du modèle d'information commun (CIM - common information model) spécifié dans la CEI 61970-301. Elle définit un ensemble normalisé d'extensions du modèle d'information commun (CIM), qui prennent en charge les définitions de message données dans la CEI 61968-3 à la CEI 61968-9, la CEI 61968-13 et la CEI 61968-14. Le domaine d'application de la présente norme est le modèle d'information qui étend le CIM de base pour les besoins des réseaux de distribution, ainsi que pour l'intégration avec les systèmes d'information à l'échelle de l'entreprise qui sont typiquement utilisés dans les entreprises de distribution électrique. Les principaux changements par rapport à la première édition sont résumés ci-dessous:
- Introduction de nouvelles classes pour prendre en charge la dénomination de manière flexible des "identified objects".
- Introduction de nouvelles classes pour prendre en charge l'échange de schémas unifilaires.
- Modèles de transport et de distribution consolidés pour les lignes, transformateurs, organes de commutation, organes de détection et autres équipements auxiliaires.

Overview

IEC 61968-11:2013 is an international standard developed by the International Electrotechnical Commission (IEC) that extends the Common Information Model (CIM) to support electric utility distribution management systems. It is part 11 of the IEC 61968 series, which focuses on system interfaces for distribution management. This standard specifically provides distribution network extensions to the CIM defined in IEC 61970-301, enabling seamless integration and data exchange within electrical utility enterprise systems.

The IEC 61968-11 standard addresses modern distribution management needs by defining a comprehensive information model that improves interoperability between distribution network components and enterprise-wide systems. The second edition introduces significant enhancements such as new classes for flexible naming of identified objects, single line diagram exchanges, and consolidated models for transmission and distribution assets.

Key Topics

• Common Information Model (CIM) Extensions
  IEC 61968-11 specifies a set of CIM extensions tailored for distribution networks to complement base CIM models outlined in IEC 61970-301. These extensions facilitate detailed modeling of electrical distribution assets and systems.

• Message Support for Distribution Management
  The standard defines information models that support message definitions used in various parts of IEC 61968, including parts 3 to 9, 13, and 14, ensuring standardized communication protocols for distribution systems.

• Enhanced Network Modeling
  New classes and UML model specifications facilitate accurate and flexible representation of distribution network topology, including lines, transformers, switching devices, sensing equipment, and auxiliary components.

• Integration with Enterprise Systems
  IEC 61968-11 supports integration between distribution management and enterprise-wide information systems commonly used within electric utilities, enabling holistic asset and customer management.

• Data Structure Improvements
  Introduces classes for flexible naming, single line diagram exchange, and consolidated transmission-distribution asset models to enhance data interoperability and system coherence.

Applications

• Distribution Management Systems (DMS)
  Utilities can use IEC 61968-11 to implement robust DMS platforms that rely on standardized data exchange to optimize network operations, fault detection, and system restoration.

• Asset Management
  The extended CIM supports comprehensive modeling and lifecycle management of distribution assets such as cables, transformers, and switches, improving maintenance planning and asset utilization.

• Enterprise Integration
  This standard enables seamless interfacing of distribution network data with enterprise resource planning (ERP), customer information systems (CIS), and billing solutions, streamlining business and operational workflows.

• Interoperability in Smart Grids
  IEC 61968-11 facilitates interoperability across various systems and vendors, which is critical for deploying smart grid technologies and advanced distribution automation.

• Single Line Diagram Exchange
  The introduced classes for single line diagrams support improved data exchange and visualization of electrical distribution networks for engineering and operational purposes.

Related Standards

• IEC 61970-301
  Defines the base Common Information Model (CIM) for energy management systems; IEC 61968-11 extends this model to cater specifically to distribution networks.

• IEC 61968 Series Parts 3-9, 13, and 14
  These parts specify message interfaces for various distribution management functions such as outage management, network operation, and data acquisition that align with the CIM extensions.

• IEC 62325
  Focuses on energy market communications and interoperability, complementing CIM for broader electric utility communications.

• IEC 61850
  Standard for communication networks and systems in substations, often integrated with CIM-based distribution and transmission management.
