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]： IEC 61970-301:2016 RLV 包含官方 IEC 国际标准及其红线版本。 Redline 版本仅提供英文版本，为您提供了一种快速、简单的方法来比较官方 IEC 标准与其先前版本之间的所有更改。 IEC 61970-301:2016 规定了通用信息模型 (CIM)，它是一个抽象模型，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 有助于集成由不同供应商独立开发的网络应用程序、运行独立开发的网络应用程序的整个系统之间或运行网络的系统之间应用程序和其他涉及电力系统运行不同方面（例如发电或配电管理）的系统。 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。相对于之前的版本，这个新版本包括以下重大技术变化： - 新的接地模型，包括 Petersen 线圈； - HVDC 模型；添加静态无功补偿模型； - 移相变压器更新； - 基于IEC 60909的短路计算； - 添加非线性并联补偿器； - 添加稳态计算输入模型，稳态假设； - 增加基频模型； - 附件 A 添加了自定义扩展。 [外文原描述]： IEC 61970-301:2016 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC 61970-301:2016 lays down the common information model (CIM), which is an abstract model that represents 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 network applications developed independently by different vendors, between entire systems running network applications developed independently, or between a system running network applications 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 centre 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. This new edition includes the following significant technical changes with respect to the previous edition: - new model for grounding including Petersen coils; - models for HVDC; addition of Static Var Compensation models; - phase shift transformer updates; - short circuit calculations based on IEC 60909; - addition of non-linear shunt compensator; - addition of model for steady state calculation inputs, Steady State Hypothesis; - addition of base frequency model; - Annex A with custom extensions added.
