2. Integrated Distribution Management System

3. Network Operations Model
• Network Operations model is the core model of the e-
terradistribution Distribution Management System.
• It maintains both the static and the dynamic data describing the
distribution network.
• The data is structured to support all the required functionality of
DMS: real-time operations, network analysis functions, and user
interface displays for the distribution network.

4. Alstom - Network Operations Model
• Based on Common Information Model (CIM).
• The CIM provides a standard way of representing power system
resources as object classes and attributes along with their
relationships. This is accomplished by defining a common
language (i.e., semantics and syntax). It is a schema, not a
database or a specific data file format.
• IEC 61970/68
• The Circuits (Feeders) are grouped together into Substations.
