由于配电网节点和线路数多，所以为了更好地实现配电网集中式差动保护，有必要将电网进行分区控制，以适应集控中心对信息采集和处理的要求。将配电网转化成带权的广义节点的网络，然后从图论的角度对配电网进行抽象，根据各广义节点间的拓扑结构来进行分区。通过利用“吸收法”对电网抽象图模型进行不断的简化和解环处理，最终将复杂电网分割成若干个广义节点的集合，即分割成若干个控制区域。

In order to make the centralized differential protection methods being better applied, it is necessary to control the distribution network partition to adapt the request of data acquisition and processing, since the number of buses and branches are large in the distribution network. This paper transforms the distribution network into a weighted network of generalized nodes, and then abstracts it in the view of graph theory. The network is partitioned according to the topological structure of each node. A new theory called Absorbing Method is put forward to simplify the abstract model of distribution network and deal with it by looped network continuously, through which a complex network is partitioned into some generalized node regions.
