Electric System Modeling

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.
