标准摘要
[中文适用范围]： 本部分IEC 61850系列介绍了IEC 61850-7-x系列各部分中使用的建模方法、通信原理和信息模型。本部分IEC 61850系列的目的是从概念的角度提供帮助，以理解用于电力公用事业自动化系统的变电站特定信息模型、用于电力公用事业自动化目的的装置功能以及提供电力公用事业设施内互操作性的通信系统的基本建模概念和描述方法。此外，本部分IEC 61850系列提供了关于IEC 61850-7-4、IEC 61850-7-3、IEC 61850-7-2和IEC 61850-5之间关系的解释和详细要求。本部分解释了IEC 61850-7-x系列的抽象服务和模型如何映射到IEC 61850-8-1中定义的具体通信协议。本部分IEC 61850系列提供的概念和模型也可用于描述其他信息模型和功能，如水电站变电站间信息交换、分布式自动化信息交换、变电站与控制中心信息交换、计量信息交换、状态监测和诊断信息交换以及与工程系统的装置配置信息交换。 [外文原描述]： IEC 61850-7-1:2011+A1:2020 introduces the modelling methods, communication principles, and information models that are used in the various parts of the IEC 61850-7 series. The purpose is to provide - from a conceptual point of view - assistance to understand the basic modelling concepts and description methods for: - substation-specific information models for power utility automation systems, - device functions used for power utility automation purposes, and - communication systems to provide interoperability within power utility facilities. Compared to the first edition, this second edition introduces: - the model for statistical and historical statistical data, - the concepts of proxies, gateways, LD hierarchy and LN inputs, - the model for time synchronisation, - the concepts behind different testing facilities, - the extended logging function. It also clarifies certain items. This consolidated version consists of the second edition (2011) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
