标准摘要
[中文适用范围]： IEC 61850-7-4:2010+A1:2020 规定了通常与电力公用事业自动化系统中的应用程序的常用相关的设备和功能的信息模型。它还包含变电站设备和功能相关应用的信息模型。特别是，它指定了智能电子设备（IED）之间通信的兼容逻辑节点名称和数据对象名称。这包括逻辑节点和数据对象之间的关系。相对于上一版本的主要技术变化如下： - 根据用户社区提出的技术问题进行更正和澄清；电能质量域新逻辑节点的扩展； - 统计和历史统计数据模型的扩展； - 关于 IEC 61850-90-1 的扩展； - 根据 IEC 62271 监控功能的新逻辑节点的扩展； - 来自普遍关注的 IEC 61850-7-410 和 IEC 61850-7-420 的新逻辑节点。本出版物与智能电网具有核心相关性。该合并版本由第二版（2010年）及其修正案1（2020年）组成。因此，无需对本出版物进行修订。关键词：低压直流 [外文原描述]： IEC 61850-7-4:2010+A1:2020 specifies the information model of devices and functions generally related to common use regarding applications in systems for power utility automation. It also contains the information model of devices and function-related applications in substations. In particular, it specifies the compatible logical node names and data object names for communication between intelligent electronic devices (IED). This includes the relationship between logical nodes and data objects. Major technical changes with regard to the previous edition are as follows: - corrections and clarifications according to technical issues raised by the users' community; extensions for new logical nodes for the power quality domain; - extensions for the model for statistical and historical statistical data; - extensions regarding IEC 61850-90-1; - extensions for new logical nodes for monitoring functions according to IEC 62271; - new logical nodes from IEC 61850-7-410 and IEC 61850-7-420 of general interest. This publication is of core relevance for Smart Grid. This consolidated version consists of the second edition (2010) and its amendment 1 (2020). Therefore, no need to order amendment in addition to this publication.
