标准范围

IEC 61970-456:2021属于IEC 61970-450至IEC 61970-499系列，作为一个整体，在抽象层面上定义了用于在电力系统分析应用、控制中心和/或控制中心组件之间传输数据的内容和交换机制。本文档的目的是严格定义来自CIM的类、类属性和角色的子集，这些子集是描述状态估计、潮流和其他类似应用的结果所必需的，这些应用产生电力网络的稳态解决方案，在本文档中包含了信息性的一组用例下。本文档面向两个不同的受众，即数据生产者和数据接收者，可以从这两个角度阅读。从数据生产者使用的模型导出软件的角度来看，该文档定义了生产者如何描述网络案例的实例，以便使其可用于其他程序。从消费者的角度来看，该文档定义了导入软件必须能够解释的内容，以便消耗潮流情况。有许多不同的用例，预期使用本文档，并且它们在每种情况下应用本文档的方式不同。实施者应该考虑他们希望覆盖的用例，以便知道他们必须覆盖的不同选项的范围。例如，本文档中定义的配置文件在某些情况下将用于交换起始条件而不是已解决的条件，因此如果这是一个重要的用例，这意味着消费者应用程序需要能够处理未解决的状态以及已满足某些解决标准的状态。这第三版取消并取代了2018年出版的第二版。本版构成技术修订版。它基于2020年8月24日发布的IEC 61970 UML版本“IEC61970CIM17v40”。与上一版相比，此版本包括以下重大技术变更:a)更新以支持CIM17(IEC 61970-301:2020+AMD1)并与IEC 61970保持一致？452:第4版。b)将PowerElectronicsConnection、PowerElectronicsUnit和PowerElectronicsWindUnit类别添加到稳态假设(SSH)配置文件中，以匹配IEC 61970-452第4版核心设备配置文件所做的更改。c)增加了本文件中使用的相关术语。d)明确了设备在役和设备正常在役的使用。

IEC 61970-456:2021 belongs to the IEC 61970-450 to IEC 61970-499 series that, taken as a whole, defines at an abstract level the content and exchange mechanisms used for data transmitted between power system analyses applications, control centres and/or control centre components.
The purpose of this document is to rigorously define the subset of classes, class attributes, and roles from the CIM necessary to describe the result of state estimation, power flow and other similar applications that produce a steady-state solution of a power network, under a set of use cases which are included informatively in this document.
This document is intended for two distinct audiences, data producers and data recipients, and can be read from those two perspectives. From the standpoint of model export software used by a data producer, the document defines how a producer may describe an instance of a network case in order to make it available to some other program. From the standpoint of a consumer, the document defines what that importing software must be able to interpret in order to consume power flow cases.
There are many different use cases for which use of this document is expected and they differ in the way that the document will be applied in each case. Implementers are expected to consider what use cases they wish to cover in order to know the extent of different options they must cover. As an example, the profiles defined in this document will be used in some cases to exchange starting conditions rather than solved conditions, so if this is an important use case, it means that a consumer application needs to be able to handle an unsolved state as well as one which has met some solution criteria.
This third edition cancels and replaces the second edition published in 2018. This edition constitutes a technical revision. It is based on the IEC 61970 UML version ‘IEC61970CIM17v40’, dated 2020-08-24.
This edition includes the following significant technical changes with respect to the previous edition:
a) Updated to support CIM17 (IEC 61970-301:2020+AMD1) and align with IEC 61970？452:ED4.
b) The classes PowerElectronicsConnection, PowerElectronicsUnit and PowerElectronicsWindUnit are added to the Steady State Hypothesis (SSH) profile to match the changes done for Edition 4 of IEC 61970-452, Core Equipment profile.
c) Added relevant terms used in this document.
d) Clarified use of Equipment.inService and Equipment.normallyInService.
