基于IEC61850的光伏并网逆变器模型构建

The modeling of photovoltaic grid inverter based on IEC61850

针对分布式能源设备缺乏统一的通信标准问题,以光伏并网逆变器为例,建立了符合IEC61850 ed2.0标准的智能电子设备IED信息模型,以实现不同厂家生产的分布式能源设备之间的互操作性。文章详细分析了光伏并网逆变器应具备的功能,设计了该IED包含的逻辑节点、数据对象和逻辑设备,逐步建立了光伏并网逆变器的信息模型和信息交换服务,为符合IEC61850标准的分布式能源设备的开发提供参考。

To eliminate the lack of International unified standard for communication of distributed energy equipment, with the photovohaics grid-connect inverter, for example, an information model of intelligent electronic device （lED） in accordance with IEC61850 ed2.0 standard is established, thus realizing the interoperability between different manufacturers＇ equipment. In this paper, the functions of photovoltaics grid-connect inverter is first detailed. Next, the logical node, data objects and logical devices of the IED are designed, and then the information model and exchange service of photovoltaics grid-connect inverter are gradually established. This research provides a useful reference for the development of distributed energy equipment in accordance with IEC61850 standard.
