GB/T 43259.301-2024 — The Common Information Model (CIM) is an abstract model that describes all major objects in an electric power enterprise, especially those related to electric power operation.

CIM provides a standard way to represent power system resources using object classes and attributes and the relationships between them. It can realize the integration and interoperability of energy management system (EMS) applications independently developed by different manufacturers.

CIM defines a the common language (i.e., semantics) based on CIM facilitates integration, allowing these applications or systems to communicate independently of the internal representation of information.

GB/T 43259 mainly includes two aspects. Common Information Model (CIM) and Component Interface Specification (CIS).

The Component Interface Specification (CIM) specifies the semantics of the EMS-API, and the Component Interface Specification (CIS) specifies the content of the message exchange.

CIM is an abstract model that represents all the major objects contained in the model required for various aspects of power enterprise operation.

The model contains the common classes and properties of these objects, as well as the relationships between them.

This document defines the basic package set of CIM, which provides energy management system functions including supervisory control and data acquisition (SCADA).

XXXIX

Other functional areas are separately standardized in other documents that supplement and reference this document. For example, IEC 61968-11 deals with power distribution models and references this document. Although there are multiple standards covering different parts of the CIM, all of these standard documents the information models of the components together constitute the CIM.

Energy Management System Application Programming Interface (EMS-API) Part 301: Common Information Model (CIM) Foundations

1 Scope

The Common Information Model (CIM) is an abstract model that describes all major objects in an electric power enterprise, especially those related to electric power operation.

CIM provides a standard way to represent power system resources using object classes and attributes and the relationships between them.

It can realize the integration and interoperability of energy management system (EMS) applications independently developed by different manufacturers.

Integration between EMS systems and other systems involved in different aspects of power system operation, such as generation or distribution management systems the SCADA system needs to be modeled to support the communication between the power system simulation and the control center. CIM defines a the common language (i.e., semantics) based on CIM facilitates integration, allowing these applications or systems to communicate independently of the internal representation of information.

Access public data and exchange information.

The object classes described in CIM are abstract in nature and can be used in a variety of applications.

This document should be understood as a tool that can be used to achieve integration in any field where a common electrical system is needed.

The goal is to build a force system model to promote interoperability and plug-and-play between applications and systems, independent of any specific implementation.

Since the complete CIM is large in size, the object classes contained in the CIM are divided into several logical packages, each of which represents the entire A certain part of a power system needs to be modeled. A collection of these packages has evolved into a separate standard. This document specifies a set of basic packages that Provides a logical view of the Energy Management System (EMS) functionality and the power system shared between all applications within the power enterprise Modeling information. Other standards specify more specific parts of the model that are only required for a particular application.
