IEC TR 61850-90-27:2023是一份技术报告，旨在提供使用IEC 61850进行系统和组件之间的信息交换时需要考虑的基本方面，以支持连接到电力网络的热系统的应用。与电力网络隔离的热系统不在本文件的范围内。 从类别的角度来看，本文件考虑了为住宅和/或商业建筑和地区提供热能服务的热力系统。换句话说，工业热系统不在本文件的范围内。 从能源转型的角度，这个文件处理的是介于电力和热能之间的。其他类型的能源，如天然气，将在未来的报告中记录。从资源的角度来看，本文件考虑了热能发电机、存储和负载的一般方面，这些方面可能有助于电力网络的运行和管理。它还处理具有电气部分的特定类型的资源，例如作为一种电力负载的热电联产（P2H）和作为发电机的热电联产（CHP）。本文档模拟了此类特定资源单元的特征，包括警报和评级。另一方面，不按本文件范围处理其他类型的具体单位。例如，燃气锅炉、热能罐、热交换器、HVAC、热系统的辅助设备在本文档中没有被建模为逻辑节点。 作为总结，本文件 -概述了连接到电力网络的热能资源。 -提供热系统典型操作的用例，并扣除信息建模所需的交换信息。 -根据用例提供LN上的需求映射。 -为热系统中的资源定义通用逻辑节点。 -为P2H和CHP的特定单元类型定义逻辑节点。 -定义用于可能有助于电力网络的操作的操作的逻辑节点。

IEC TR 61850-90-27:2023, which is a Technical Report, is to provide basic aspects that need to be considered when using IEC 61850 for information exchange between systems and components to support applications for thermal systems connected to electric power networks. Thermal systems isolated from electric power networks are outside the scope of this document.
From the perspective of category, this document considers thermal systems that provide thermal energy services for residential and/or commercial buildings and districts. In other words, industrial thermal systems are outside the scope of this document.
From the perspective of energy transformation, this document deals with ones between electricity and thermal energy. Other types of energy such as gas will be documented in a future report.
From the perspective of resource, this document considers generic aspects of thermal energy generators, storage, and loads that may contribute to the operations and management of electric power networks. It also deals with specific types of resources that have electric parts such as power to heat (P2H) that is a kind of electric load, and combined heat and power (CHP) that is an electric generator. This document models the characteristics for such specific units of resources including alarms and ratings. On the other hand, it does not deal with other types of specific units according to the scope of this document. For example, gas boilers, thermal energy tanks, heat exchangers, HVAC, auxiliary devices for thermal systems are not modelled as logical nodes in this document.
As a summary, this document
- gives an overview of thermal energy resources connected to electric power networks.
- provides use cases for typical operations of thermal system and deducts exchanged information necessary for information modelling.
- provides mapping of requirements on LNs based on the use cases.
- defines generic logical nodes for resources in thermal systems.
- defines logical nodes for specific unit types of P2H and CHP.
- defines logical nodes for operations that may contribute to the operations of electric power networks.
