能源管理系统应用程序接口(EMS-API).第301部分:通用信息模型(CIM)基础

[中文适用范围]： 通用信息模型 (CIM) 是一个抽象模型，代表电力企业中通常涉及公用事业运营的所有主要对象。通过提供一种将电力系统资源表示为对象类和属性及其关系的标准方法，CIM 促进了由不同供应商独立开发的能源管理系统 (EMS) 应用程序、独立开发的整个 EMS 系统之间或不同系统之间的集成。 EMS系统和其他涉及电力系统运行不同方面的系统，例如发电或配电管理。 SCADA 的建模达到了支持电力系统仿真和控制中心间通信所需的程度。 CIM 通过定义基于 CIM 的通用语言（即语义）来促进集成，使这些应用程序或系统能够访问公共数据并交换信息，而不管这些信息在内部如何表示。 [外文原描述]： IEC 61970-301:2013 defines the Common Information Model (CIM), that is an abstract model representing all the major objects in an electric utility enterprise typically involved in utility operations. By providing a standard way of representing power system resources as object classes and attributes, along with their relationships, the CIM facilitates the integration of Energy Management System (EMS) applications developed independently by different vendors, between entire EMS systems developed independently, or between an EMS system and other systems concerned with different aspects of power system operations, such as generation or distribution management. SCADA is modeled to the extent necessary to support power system simulation and inter-control center communication. The CIM facilitates integration by defining a common language (i.e. semantics) based on the CIM to enable these applications or systems to access public data and exchange information independent of how such information is represented internally. Major changes from the fourth edition include the following: - transformer models have been modified to be consistent for use by distribution and transmission purposes; - a more general and clear naming approach was added and several ambiguous attributes related to naming were dropped; - phase component wires models have been enhanced to describe internal phase specific attributes and connections; - addition of diagram layout models to facilitate the exchange of diagram layout information.
