基于相似端匹配的智能站虚端子连接准确性判断方法研究

Study on the Accuracy Judgment Method of Virtual Terminal Connection of Intelligent Station Based on Similar End Matching

智能变电站的二次系统调试常会由于虚端子连接错误、系统冗余过量等问题,导致出现系统错误、工作效率低、虚端子连接判断困难的现象。针对此现象,提出了一种基于相似端匹配的智能站虚端子连接准确性判断方法。首先说明虚端子的数据格式,然后以虚端子连接关系为判断对象、虚端子特点为判断依据,优化Dice距离相似度提升判断准确性,完成判断方法设计后以220 kV智能站为基础进行算例分析,最终确认判断方法的合理性。

The secondary system debugging of intelligent substations often leads to system errors,low work efficiency,and difficulty in judging virtual terminal connections due to problems such as virtual terminal connection errors and excessive system redundancy.In order to solve this phenomenon,a method for judging the accuracy of virtual terminal connection of intelligent station based on similar end matching is proposed.Firstly,the data format of the virtual terminal is explained.Then,the virtual terminal connection relationship is taken as the judgment object and the virtual terminal characteristics are used as the judgment basis,and the Dice distance similarity is optimized to improve the judgment accuracy.After completing the design of the judgment method,the 220 kV intelligent station is used to analyze the example,and the rationality of the judgment method is finally confirmed.
