What is
the electric system model?
In order for an IT system to successfully implement business processes
and business rules surrounding operations scheduling, logging,
and reporting, it is essential that it provides a database that
is a complete and comprehensive representation of your electric system.
The most effective IT systems will capture the physical elements in your
electric system, and the information about the business and regulatory
environments in which they operate, in a cohesive electric system model.
Physical elements within the electric system model
include —
- Substations and Generating Stations
- Transmission Lines
- Distribution Feeders
- Switches
- Buses
- Circuit Breakers and Disconnects
- Generators
- Transformers
- Reactors
- Capacitors
Information about the business/regulatory environment might
include —
- Control Areas
- Asset Owners
- Asset Operators
- Asset Managers
- Districts
- Other Business Units
- People and Roles
- Reporting Hierarchies
- Data Access Permissions
The Equinox CROW allows you to create and manage a complete
and comprehensive electric system model.
The Control Room Operations Window (CROW) captures your complete
electric system model utilizing the Equinox Enterprise Model
technology
-- a flexible metadata-based technology designed specifically for
modeling systems. Implemented as a
module within CROW, the Enterprise Model contains an EPRI Common Information
Model (EPRI CIM)-compliant database that allows you to store, manage, and
utilize any and all information regarding your physical electric system and the
business and regulatory environment in which it operates.
Whether you choose to represent your electric system as a simple
list of stations, lines, and equipment, or as a complete, real-world electric
system model, the CROW
Enterprise Model provides an easy-to-use
interface and powerful features to help create and maintain your data.
The CROW Enterprise Model
provides hierarchical and
graphical schematic views of the electric system model along with user-friendly
tools for querying and updating the model.
The CROW Enterprise Model
fully supports the archiving of historical data. When
equipment is decommissioned or otherwise removed from the electric system, it
remains archived in the electric system model. You are then able to prevent the recording of new data on the
decommissioned element while still allowing users to query and report on the
history of events that involved that element.
CROW also provides the ability to maintain a
historical record of the property values of any element in the electric
system model. As an example, a circuit
breaker element may have a property identifying the switch state as
"Closed" or "Open". Whenever that property is
changed, the CROW Enterprise
Model logs that change in the property history.
CROW can be used for any system modeling
need.
As a full modeling system, the CROW Enterprise Model is
exceptionally comprehensive and is able to support
an extensive variety of modeling needs including -- and not limited to --
network models, component assemblies, protection system models, and engineering
properties. The data in these models
can be utilized to enable customized business processes within CROW or
be accessed as a database for external IT applications through an
Application Programming Interface or SOAP/XML interface.

your company a technology advantage, or for more technical information,
