标准摘要
[中文适用范围]： IEC 61850 的这一部分规定了通常与电力公用事业自动化系统中的应用程序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。本文档中定义的逻辑节点名称和数据对象名称是 IEC 61850-7-1 中引入并在 IEC 61850-7-2 中定义的类模型的一部分。本文档中定义的名称用于构建分层对象引用，该对象引用应用于与电力公用事业自动化系统中的 IED 进行通信，特别是与变电站和配电馈线上的 IED 进行通信。本部分采用 IEC 61850-7-2 的命名约定。为了避免私有的、不兼容的扩展，本部分指定了多个实例的规范命名规则以及逻辑节点（LN）类和数据对象名称的私有的、兼容的扩展。任何定义均基于 IEC 61850 或参考明确的公共文档。本部分不提供教程材料。建议首先阅读 IEC 61850-5 和 IEC 61850-7-1 部分，并结合 IEC 61850-7-3 和 IEC 61850-7-2。 [外文原描述]： IEC 61850-7-4:2010 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.
