摘要:

提出一种基于二维混沌正余弦算法的虚回路自动连接技术,首先采用Jaro-Winkler距离构建了涉及距离权重向量的虚端子匹配模型,然后在虚连接历史数据的基础上利用二维混沌正余弦算法求解最优距离权重向量,最后以蒙东某66 kV变电站为例,采用所提方法进行虚端子匹配。结果表明:相比现有技术该方法所得虚端子连接结果更准确且匹配效率更高。

Abstract:

In this paper, a virtual loop automatic connection technology based on two-dimensional chaotic sine-cosine algorithm is proposed. Firstly, a virtual terminal matching model involving distance weight vector is constructed by using Jaro-Winkler distance. Then, on the basis of the historical data of virtual connection, the optimal distance weight vector is solved by using the two-dimensional chaotic sine-cosine algorithm. Finally, a 66 kV substation in eastern Mongolia is taken as an example to match virtual terminals with the proposed method. The results show that the virtual terminal connection results obtained by the proposed method are more accurate and more efficient than those obtained by the prior art.

Key words: virtual terminal, automatic connection, distance weight vector
