基于关键字符匹配的虚端子自动关联方法

摘要

The connection of virtual terminals is a main point in the secondary design procedure of the smart substation. By analysis of the data format and naming convention of the virtual terminals, a method for automatically connecting the virtual terminals based on the key-character matching is proposed. First, a template file of connected virtual terminals are set up;then, by the key-character matching, the virtual terminals in the connection-waiting file are made consistent with the congenerous ones in the template file in terms of their positions. Using this method, this paper automatically connects most virtual terminals with various models and various manufacturers. For a few virtual terminals that can’t be automatically connected and manual connection is adopted through narrowing the range of choice. The proposed method can alleviate work load and improve the design efficiency and quality.%关联虚端子是智能变电站二次设计的主要内容，在对虚端子的数据格式和命名规范进行分析的基础上，提出了基于关键字符匹配原理的虚端子自动关联方法。该方法首先设置关联好的虚端子模板文件，再通过关键字符匹配使待关联文件中的虚端子与模板文件中功能相同的虚端子位置一致，从而实现对不同厂家不同型号的大部分虚端子自动关联；对于少量不能自动关联的虚端子，可缩小选择范围后手动关联。该方法能有效减少设计工作量，提升设计效率和质量。
