标准摘要
[中文适用范围]： 本IEC 61850标准文件是一篇技术报告，旨在解释如何利用IEC 61850-7-410中定义的逻辑节点以及IEC 61850系列中的其他文档，对电厂中的复杂控制功能进行建模，包括变速抽水蓄能电厂。IEC 61850-7-410引入了电厂建模的通用IEC 61850概念，但标准中并未显而易见地说明如何在实际电厂中实施这些建模概念。本文档解释了IEC 61850标准中定义的数据模型和概念如何应用于水电（既直接应用于过程控制级别，也应用于更高级别的数据结构化和数据交换）。热电厂应用数据模型的范围限于电力排出（原则上提取所产生的电力）以及原动机轴和轴承系统。燃料和蒸汽阀门的接口建模仅用于过程控制的目的。通信服务和IEC 61850数据模型到不同通信协议的映射描述不在本文档的范围内。 [外文原描述]： IEC TR 61850-7-510:2021(E), which is a technical report, is intended to provide explanations on how to use the Logical Nodes defined in IEC 61850-7-410 as well as other documents in the IEC 61850 series to model complex control functions in power plants, including variable speed pumped storage power plants. IEC 61850-7-410 introduced the general modelling concepts of IEC 61850 for power plants. It is however not obvious from the standard how the modelling concepts can be implemented in actual power plants. This document explains how the data model and the concepts defined in the IEC 61850 standard can be applied in Hydro; both directly at the process control level, but also for data structuring and data exchange at a higher level. Application of the data model for Thermal is limited to power evacuation (in principle the extraction of the generated electrical power) and the prime mover shaft and bearing system. The interfaces of the fuel and steam valves are modelled for the purpose of process control. Communication services, and description of the use of mappings of the IEC 61850 data model to different communication protocols, are outside the scope of this document. This second edition cancels and replaces the first edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) Process modelling according to IEC 61850-6:2009, including IEC 61850-6:2009/AMD1:2018. b) Examples of application of Reference Designation System together with the process modelling, in particular application of IEC/ISO 81346. c) Description of modelling related to Steam- and Gas turbines. d) Annexes with examples of application of SCL according to the examples in the Technical Report. e) The dynamic exchange of values by using polling, GOOSE, Reporting or Sampled Values is no longer included in the Technical Report.
