标准摘要
[中文适用范围]: 本IEC 61850第90-7部分描述了基于功率转换器的分布式能源(DER)系统功能,重点涵盖直流到交流和交流到交流的转换,包括光伏系统(PV)、电池储能系统、电动汽车(EV)充电系统以及任何其他带有可控功率转换器的DER系统。它定义了IEC 61850信息模型,用于在这些基于功率转换器的DER系统与负责管理这些系统电压、无功和有功能力的公用事业公司、能源服务提供商(ESP)或其他实体之间交换信息。这些基于功率转换器的DER系统范围可以从住宅客户场所的小型并网系统,到校园或社区配置的中规模微电网系统,再到公用事业运营的大型发电厂系统,以及许多其他配置和所有权模式。它们可能或不结合不同类型的DER系统,例如在直流层面连接的基于功率转换器的DER系统和电池。本文件的命名空间为:"(Tr) IEC 61850-90-7:2012"。命名空间"IEC 61850-90-7"被视为"过渡性",因为这些模型预计将被包含在IEC 61850-7-420中。如果/当模型移动到国际标准状态时,可能会发生扩展/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。其他仍应引用其主要定义的命名空间。注意:术语"功率转换器"被用于"逆变器",因为它涵盖了从输入到输出功率的更多类型转换:交流到直流(整流器)、直流到交流(逆变器)、直流到直流(DC-DC转换器)、交流到交流(AC-AC转换器)。 [外文原描述]: IEC/TR 61850-90-7:2013(E) describes the 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. It defines the IEC 61850 information models to 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.
