基于短地址关联数据标识的智能变电站虚回路可视化技术研究及应用

Research and application of virtual circuit visualization technology in smart substation based on the short address associated data identification

智能变电站二次回路间通过光缆连接,其虚端子间的连接关系不具有物理上的直观可视特性,研究虚回路的可视化技术具有重要意义。针对虚回路中功能投退软压板无法自动关联和展示的问题,通过在ICD文件的短地址上扩展软压板的关联数据标识,并在SCD文件中检索相同的关联数据标识,实现虚端子与软压板的自动关联;此外,对短地址关联数据标识统一设计,并实时更新相关联数据,实现虚回路中虚端子数值的实时显示;工程设计时,通过设计可导入到SCD文件的装置端口配置表,提高虚回路可视化精确度,可精确到IED间的具体端口。相关研究成果已获得工程应用,可完整体现含软压板二次回路的连接关系,提高智能变电站运行维护的便捷性。

Since the secondary circuits of the intelligent substation are connected by optical cables,the connection relationship between the virtual terminals is not physical intuitive.It is of great significance to study the visual technology of the virtual circuits.In the virtual circuit,the functional soft plate cannot be automatically associated and displayed.Therefore,the associated data identifier of the soft plate is added to the sAddr(short address)of the ICD file,and then the same associated data identifier is retrieved in the SCD file to realize automatic association between the virtual terminal and the soft pressure plate.In addition,the sAddr associated data identifier is uniformly designed,and the associated data is updated in real time to realize real-time display of virtual terminal values in the virtual loop.In engineering design,the device port configuration table which can be imported into the SCD file is designed beforehand to improve the visual accuracy of virtual circuit to a specific port between the IEDs.The relevant research results are applied in engineering.The connection relationship of secondary circuit including the soft plate is fully reflected,and the convenience of operation and maintenance of the intelligent substation is also improved.
