电力设施自动化用通信网络和系统.第1-2部分:扩展IEC 61850的指南

[中文适用范围]： 本部分IEC 61850是一份技术规范，适用于任何用户，但主要针对标准化机构，这些机构考虑在其工作范围内使用IEC 61850作为基础标准，并愿意按照IEC 61850标准允许的范围进行扩展。本文档确定了实现IEC 61850此类扩展所需的步骤和高级要求，并为各个步骤提供了指南。在此范围内，本文档涉及以下情况： - 基于IEC 61850接口的产品级标准的管理 - 基于IEC 61850的领域级标准的管理 - 基于IEC 61850的过渡标准的管理 - 基于IEC 61850的私有命名空间的管理 - 开发提供IEC 61850数据模型在CDC级别映射的标准 - 开发和管理针对领域的IEC 61850配置文件（基于IEC TR 62361-103和IEC TR 61850-7-6的作用） 本文档包括技术和流程两个方面： 在技术方面，本文档： - 强调主要的基本要求（主要参考包含要求或建议的系列适当部分） - 列出标准提供的所有可能的灵活性 - 定义每种扩展情况下允许/可能的灵活性 在流程方面，本文档涵盖： - 初步分析现有IEC 61850对象模型和/或通信服务如何应用，以及在新或特定领域（包括私有领域）中利用它们可能需要哪些允许的扩展。此步骤的结果预期将被记录 - 为新领域扩展IEC 61850对象模型。相关的典型工作是识别可以“原样”重用的现有逻辑节点，确定是否可以扩展现有逻辑节点，或定义新的逻辑节点 - 使用过渡命名空间的目的和流程，这些命名空间最终将合并到现有的标准命名空间中 - 标准命名空间的管理 - 私有命名空间的开发 [外文原描述]： IEC TS 61850-1-2:2020, which is a technical specification, is intended for any users but primarily for standardization bodies that are considering using IEC 61850 as a base standard within the scope of their work and are willing to extend it as allowed by the IEC 61850 standards. This document identifies the required steps and high-level requirements in achieving such extensions of IEC 61850 and provides guidelines for the individual steps. Within that scope, this document addresses the following cases: • The management of product-level standards for products that have an interface based on IEC 61850 • The management of domain-level standards based on IEC 61850 • The management of transitional standards based on IEC 61850 • The management of private namespaces based on IEC 61850 • The development of standards offering the mapping of IEC 61850 data model at CDC level • The development and management of IEC 61850 profiles for domains (underlying the role of IEC TR 62361-103 and IEC TR 61850-7-6) This document includes both technical and process aspects: On the technical side, this document: • Reminds the main basic requirements (mostly referring to the appropriate parts of the series which host the requirements or recommendations) • Lists all possible flexibilities offered by the standards • Defines which flexibilities are allowed/possible per type of extension cases On the process side, the document covers: • The initial analysis of how the existing IEC 61850 object models and/or communication services may be applied and what allowed extensions may be required for utilizing them in new or specific domains (including private ones). The results of that step are expected to be documented • The extension of the IEC 61850 object models for new domains. The typical associated work is to identify existing logical nodes which can be reused "as is", to determine if existing logical nodes can be extended, or to define new logical nodes • The purpose and process to use transitional namespaces, which are expected to be merged eventually into an existing standard namespace • The management of standard namespaces • The development of private namespaces
