IEC TR 61850-7-5:20 21是一份技术报告，它建立了建模概念，帮助用户理解如何应用IEC 61850-7-4和IEC 61850-7-3中定义的模型来实现实际应用。 本文档提供了适用于所有使用IEC 61850的应用领域的基本概念。领域特定概念在IEC 61850-7-5xx的文件范围内的其他技术报告中定义；例如，IEC 61850-7-500描述了与变电站自动化相关的功能的建模概念。 一方面，跨域建模的潜在主题的数量可能非常高，但另一方面，它可能受到通常由IEC 61850在域中的历史演变产生的域特定限制的限制。 选择的第一个主题是通过电力设施自动化系统对电力设施主要对象的共同控制，主要基于变电站自动化系统的长期经验。在所有领域中，可靠的电力设施自动化系统的共同属性是质量和健康。在电力设施自动化系统中具有广泛应用范围的特殊功能是由智能电网中使用的域分布式能源(DER)提供的服务的调度，尤其是也用于电动移动。在IEC 61850的上下文中还没有太多讨论，但对于所有IED来说非常重要的是重启（电源循环）对数据模型参数的影响。不一致的行为会给多供应商系统的互操作性带来问题。

IEC TR 61850-7-5:2021, which is a technical report, establishes modelling concepts that help the user to understand how to apply the models defined in IEC 61850-7-4 and IEC 61850-7-3 to implement practical applications.
This document provides the basic concepts that are valid for all application domains using IEC 61850. Domain specific concepts are defined in other technical reports as in the document range of IEC 61850-7-5xx; as an example, IEC 61850-7-500 describes modelling concepts for functions related to substation automation.
On one side the number of potential topics for cross-domain modelling may be very high but on the other side it may be limited by domain specific restrictions often created by the historical evolution of IEC 61850 in the domains.
The first topic selected is the common control of power utility primary objects by means of the power utility automation systems based mainly on the long experience in substation automation systems. Common attributes for reliable power utility automation systems in all domains are quality and health. A special function having a broad application range in power utility automation systems is the scheduling of services as provided by the domain distributed energy resources (DER) used in smart grids, especially also for electric mobility. Not yet so much discussed in the context of IEC 61850 but very important for all IEDs is the impact of restart (power cycle) on the data model parameters. Non-agreed behaviour will raise problems for interoperability in multi-vendor systems.
