摘要

首先介绍了低压配电网拓扑发现技术现状，其次详细介绍了基于高频同步采集与边缘计算的低压配电网电气拓扑发现技术，包括数据的高频同步采集、利用皮尔逊相关系数法进行台区识别、分析电表之间的互信息、通过生成树算法生成物理拓扑等，最后进行验证和结果展示。与其他通过纯软件算法实现拓扑发现的方法相比，所提方法既能保证数据的同时性又可及时反映拓扑的变化，使得低压台区电气拓扑判断更加精准。

Abstract

Firstly

the current status of electrical topology discovery in low voltage distribution network was introduced

and then the high frequency synchronous acquisition and edge computing based electrical topology discovery in low voltage distribution network was proposed

including high-frequency synchronous data acquisition

Pearson correlation coefficient method for station area identification

analysis of mutual information between electric meters

generation of physical topology through spanning tree algorithm

and so on.Compared with other methods using pure software algorithm to realize topology discovery

the proposed method can not only ensure the simultaneity of data

but also reflect the changes of topology in time

which makes the judgment of electrical topology of low-voltage stations more accurate.
