基于典型间隔模板的智能变电站虚端子自动连接方法

Automatic connection method of virtual terminator in smart substation based on typical bay template

在目前的智能变电站集成配置过程中,集成人员根据设计院提供的虚端子连接关系表手动配置变电站系统配置描述(SCD)文件中的虚端子连接关系,不仅工作量大、耗时长,而且容易出现连接错误。为此通过分析SCD文件中Substation元素结构,以及典型间隔的虚端子连接关系,定义以二次设备类型表示智能电子设备(IED)的典型间隔虚端子连接模板。在自动配置过程中先将一次主接线图中的间隔映射为典型间隔,再将间隔内一次设备关联的IED映射为典型间隔中的二次设备类型,最后根据二次设备类型之间的虚端子连接关系为IED配置虚端子连接关系。应用该方法开发系统配置工具的虚端子自动连接功能,可模拟对新建站和改扩建工程的间隔进行虚端子自动连接,有助于缩短虚端子连接配置时间。

In the current integration configuration process of smart substation,integrators manually configure the virtual terminator connection in SCD file according to the virtual terminator connection table provided by the design institute,which is not only heavy workload,time-consuming,but also prone to connection errors. For this reason,by analyzing the structure of Substation element in SCD file and the virtual terminator connection of typical bay,a typical bay virtual terminator connection template is defined,in which the IED is represented by secondary device type. In the process of automatic configuration,the bay in the primary wiring diagram is mapped to the typical bay,and then the IED associated with the primary device in the bay is mapped to the secondary device type in the typical bay. Finally,the virtual terminator connection is configured for IED according to the virtual terminator connection between the secondary device types. This method can be used to develop the virtual terminator automatic connection function of the system configuration tool,which can simulate the virtual terminator automatic connection of the bay in the new station and the expansion project,and help to shorten the virtual terminator connection configuration time.
