IEC 61970-457:2024规定了一个标准接口，用于交换支持电力系统或其部分的稳态稳定性（小信号稳定性）和/或瞬态稳定性分析所需的动态模型信息。表示动态模型信息的模式直接来自CIM，更具体地说，来自IEC 61970-302。 本文件的范围仅包括作为动态研究的一部分需要交换的动态模型信息，即与完整电力系统网络模型的稳态解中包含的电力系统设备相关的每个控制设备的类型、描述和参数。因此，该配置文件取决于IEC 61970-452中规定的设备的其他标准配置文件:CIM静态传输网络模型配置文件、拓扑结构、稳态假设和稳态解决方案（如IEC 61970中规定的- 456:已解决的电力系统状态配置文件），这限制了交换的范围。本文档描述的配置文件信息需要与IEC 61970-452和IEC 61970—456配置文件信息一起交换，以支持瞬态分析工具的数据要求。IEC 61970-456详细描述了如何组合不同的配置文件标准以形成各种类型的电力系统网络模型交换。 本文档支持以下类型的动态模型的交换: •标准模型:一种简化的交换方法，其中模型包含在以标准方式互连的预定义类库中，这些类库表示电力系统元件的动态行为。交换仅指示模型的名称以及描述其行为所需的属性。 •专有用户定义模型:一种交换，使用户能够交换代表供应商或用户专有设备的模型参数，而本文档中没有对模型进行明确描述。专有模型和标准模型之间的连接与标准模型交换中描述的相同。数据交换的接收方需要联系发送方了解模型的行为细节。 本文档以IEC 61970-302动态CIM为基础，定义了标准动态模型的描述、功能框图以及它们如何与静态网络模型互连和关联。假设所有软件应用程序都预先存储了这类模型信息，因此不需要实时交换或作为动态模型交换的一部分进行交换。 第二版取消并取代了2021年出版的第一版。本版本为技术修订版。 与上一版相比，本版包括以下重大技术更改: a） 在IEC 61970-302:2018中检测到的大多数问题以及在IEC 61770-302:2022中修复的问题导致了本文件的更新； b） 完全涵盖了IEEE 421.5-2016关于励磁系统的内容； c） 考虑了2013年的IEEE涡轮机报告，因此增加了许多燃气、蒸汽和水力涡轮机/调速器； d） 关于风力涡轮机的IEC 61400-27-1:2020已完全纳入； e） 增加了WECC基于逆变器的资源（IBR）模型、混合STATCOM模型和存储模型； f） 用户定义模型方法在IEC 61970-302:2022中得到了增强，增加了一个模型，可以对详细的动态模型进行建模。这导致创建了两个额外的pr

IEC 61970-457:2024 specifies a standard interface for exchanging dynamic model information needed to support the analysis of the steady state stability (small-signal stability) and/or transient stability of a power system or parts of it. The schema(s) for expressing the dynamic model information are derived directly from the CIM, more specifically from IEC 61970-302. The scope of this document includes only the dynamic model information that needs to be exchanged as part of a dynamic study, namely the type, description and parameters of each control equipment associated with a piece of power system equipment included in the steady state solution of a complete power system network model. Therefore, this profile is dependent upon other standard profiles for the equipment as specified in IEC 61970-452: CIM static transmission network model profiles, the topology, the steady state hypothesis and the steady state solution (as specified in IEC 61970-456: Solved power system state profiles) of the power system, which bounds the scope of the exchange. The profile information described by this document needs to be exchanged in conjunction with IEC 61970-452 and IEC 61970-456 profiles’ information to support the data requirements of transient analysis tools. IEC 61970-456 provides a detailed description of how different profile standards can be combined to form various types of power system network model exchanges. This document supports the exchange of the following types of dynamic models: • standard models: a simplified approach to exchange, where models are contained in predefined libraries of classes interconnected in a standard manner that represent dynamic behaviour of elements of the power system. The exchange only indicates the name of the model along with the attributes needed to describe its behaviour. • proprietary user-defined models: an exchange that would provide users the ability to exchange the parameters of a model representing a vendor or user proprietary device where an explicit description of the model is not described in this document. The connections between the proprietary models and standard models are the same as described for the standard models exchange. Recipient of the data exchange will need to contact the sender for the behavioural details of the model. This document builds on IEC 61970-302, CIM for dynamics which defines the descriptions of the standard dynamic models, their function block diagrams, and how they are interconnected and associated with the static network model. This type of model information is assumed to be pre-stored by all software applications hence it is not necessary to be exchanged in real-time or as part of a dynamics model exchange. This second edition cancels and replaces the first edition published in 2021. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) The majority of issues detected in IEC 61970-302:2018 and fixed in IEC 61970-302:2022 led to update of this document; b) IEEE 421.5-2016 on Excitation systems is fully covered; c) IEEE turbine report from 2013 was considered and as a result a number of gas, steam and hydro turbines/governors are added; d) IEC 61400-27-1:2020 on wind turbines is fully incorporated; e) WECC Inverter-Based Resource (IBR) models, Hybrid STATCOM models and storage models are added; f) The user defined models approach was enhanced in IEC 61970-302:2022 adding a model which enables modelling of a detailed dynamic model. This results in the creation of two additional pr
