电力设施自动化用通信网络和系统.第90-7部分:分布式能源（DER）系统中功率变换器的对象模型

[中文适用范围]： 本部分IEC 61850是一份技术报告，描述了基于分布式能源资源（DER）系统的功率转换器功能，重点关注DC-to-AC和AC-to-AC转换，包括光伏系统（PV）、电池存储系统、电动汽车（EV）充电系统以及其他具有可控功率转换器的DER系统。本文档定义的函数用于帮助定义IEC-61850信息模型，如IEC 61850-7-420所述，并可用于这些基于功率转换器的DER系统与公用事业、能源服务提供商（ESP）或其他负责管理这些功率转换器系统的电压、无功功率和瓦特能力的实体之间的信息交换。这些基于功率转换器的DER系统可以范围从非常小的住宅客户站点的并网系统，到校园或社区的中型微电网系统，到公用事业运营的发电厂的非常大的系统，以及许多其他配置和所有权模型。它们可以在功率转换器后面组合不同类型的DER系统，例如基于功率转换器的DER系统和在DC级别连接的电池。本文档的命名空间为："(Tr) IEC 61850-90-7-2012"。命名空间"IEC 61850-90-7"被视为"过渡性"，因为模型预计将包含在IEC 61850-7-420中。如果/当模型升级为国际标准状态时，可能会发生潜在的扩展/修改。只有以粗斜体字体表示的新数据对象和CDC将标记为此命名空间名称。其他仍应参考它们主要定义的命名空间。注：术语功率转换器用于代替"逆变器"，因为它涵盖了从输入到输出功率的更多类型的转换：- AC到DC（整流器）- DC到AC（逆变器）- DC到DC（DC-DC转换器）- AC到AC（AC-AC转换器）。 [外文原描述]： IEC TR 61850-90-7:2023 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition. IEC TR 61850-90-7:2023, which is a Technical Report, describes functions for power converter-based distributed energy resources (DER) systems, focused on DC-to-AC and AC-to-AC conversions and including photovoltaic systems (PV), battery storage systems, electric vehicle (EV) charging systems, and any other DER systems with a controllable power converter. The functions defined in this document were used to help define the information models described in IEC 61850-7-420 and which can be used in the exchange of information between these power converter-based DER systems and the utilities, energy service providers (ESPs), or other entities which are tasked with managing the volt, var, and watt capabilities of these power converter-based systems. These power converter-based DER systems can range from very small grid-connected systems at residential customer sites, to medium-sized systems configured as microgrids on campuses or communities, to very large systems in utility-operated power plants, and to many other configurations and ownership models. They may or may not combine different types of DER systems behind the power converter, such as a power converter-based DER system and a battery that are connected at the DC level. This second edition cancels and replaces the first edition published in 2013. This edition is primarily an editorial revision in order to be consistent with the publication of Edition 2 of IEC 61850-7-420:2021. This edition includes the following significant changes with respect to the previous edition: a) Clause 3 has been updated. b) Clause 8 (IEC 61850 information models for power converter-based functions) has been deleted. This clause defined data models with the transitional namespace “(Tr) IEC 61850-90-7:2012”. The data models are now defined in IEC 61850-7-420.
