Integrated Distribution Management System

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.

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.
