Generic data models for breaker-oriented network representation

Constructing and maintaining the power system network model is important for ensuring reliable results. The Electric Power Research Institute's (EPRI) Common Information Model (CIM) is a comprehensive power system model that represents all the major objects in an electric utility enterprise typically contained in the Energy Management System (EMS) information model. The power system data represented in industry standard data formats, such as the IEEE Common Data Format and Power Technologies Inc. (PTI) formats, do not represent breaker data that is essential for various applications. This paper discusses the standardization of input data to power system applications with adequate breaker details in CIM format to increase the accuracy and the efficiency of these applications. The CIM based breaker-oriented format also provides flexibility for models that enables further extension.
