IEC TR 61850-90-6:20 18是一份技术报告，提供了在中压网络自动化中使用IEC 61850进行系统和组件之间的信息交换以支持配电自动化应用时需要考虑的基本方面，如附录B所示。 配电自动化（DA）的内容在不同国家、地区之间，甚至在同一国家的不同公用事业之间也有所不同。DA可以涵盖HV/MV变电站、MV网络、LV网络、分布式能源以及需求侧。特别是，本文件: ？为需要在两个或多个组件/系统之间交换信息的典型DA应用程序定义用例 ？提供DA应用程序中常用组件的建模 ？提出了可用于典型DA应用程序的新逻辑节点和对现有逻辑节点的扩展。？为DA应用程序中使用的通信体系结构和服务提供指南 ？为DA系统中使用的IED提供配置方法。

IEC TR 61850-90-6:2018, which is a technical report, provides basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components to support Distribution Automation applications, within MV network automation, as presented in Annex B.
The contents of Distribution Automation (DA) vary between different countries, regions, even between different utilities in the same country. DA may cover HV/MV substations, MV networks, LV networks, distributed energy resources, as well as demand sides. In particular, this document:
？defines use cases for typical DA applications that require information exchange between two or more components/systems
？provides modelling of components commonly used in DA applications
？proposes new logical nodes and the extensions to the existing logical nodes that can be used in typical DA applications.
？provides guidelines for the communication architecture and services to be used in DA applications
？provides configuration methods for IEDs to be used in DA systems.
