IEC 61970 Common Information Model (CIM)
The Role of CIM
Goal of CIM is to develop one Common Information Model that defines the electrical network, work management, meter data, schedules, …
Entso-e migrates to CIM and establishes
the UCTE profile for static and dynamic
model exchange
NIST has adopted the core CIM standards
together with IEC 61850 as part of the
foundations of the Smart Grid program

Data Model Access - Import / Export / Format
IMM Formats
• CIM-RDF (Resource Description Format):
standardized XML based format
• XDF (eXchange Data Format): XML based
format that is more compact
Export / Import
• Scope: Complete data model including equipment,
configuration, world maps
• Types of export / import: bulk, partial and incremental
Interface to the IMM job management
• Creation of a job
• Import of RDF / XDF data into the job
• Activation of the job

IEC 61970 Common Information Model (CIM) Time-based Models
Time-based models add the ability to reflect the evolutionary nature of work
Time-based models allow flexibility in scheduling data changes to reflect scheduling
of projects
Impact of delays or re-scheduling of projects can be managed effectively
Archived models allow for maintaining a history of data changes for any certain date
in the past
Models can be archived for post mortem analysis
Historical views of the data/model are possible

Smart Grid: First Step
Conclusión
IEC 61850 No solo ayudó a estandarizar las comunicaciones en los
sistemas de automatización de subestaciones, sino que además
permitió modelar la información de la industria eléctrica de potencia
(“logical nodes”).
IEC 61970 (CIM) es la base para integración vertical y horizontal.
Permite facilitar el intercambio de información de las redes eléctricas
entre compañias; y permitir el intercambio de información entre
aplicaciones en la misma compañía.
IEC 62357 (SOA) es una arquitectura de software que facilita la
integración de sistemas independientes (aplicaciones) en un entorno IT,
a través de un protocolo de comunicación común
