Abstract

The present invention provides a method and apparatus for identifying connection relationships between components in a power distribution network. The method includes the following steps that: the power flow distribution relationship of a target component in pre-stored power distribution network information is obtained; the connection attributes of the target component are obtained according to the power flow distribution relationship; all reference components which are located in the same connection network with the target component are identified in the power distribution network according to the connection attributes; and the connection relationships between the target component and all the reference components are highlighted. According to the method and apparatus provided by the technical schemes of the invention, the connection relationships between the target component and all the reference components which are located in the same connection network with the target component are highlighted; workers can obtain the relevant connection relationships quickly and accurately just through selecting the target component; a highlighted display mode makes the connection relationships of the components in the connection network more clear and intuitive; and therefore, errors caused by manual identification can be avoided, the identification efficiency of the connection relationships of the power distribution network can be improved, and the power outage time of the fault of the power distribution network is greatly decreased.

Description

technical field [0001] The invention relates to the field of distribution network management, in particular to a method and device for identifying the contact relationship between components in the distribution network. Background technique [0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some auxiliary facilities. It is a network that plays an important role in distributing electric energy in the power network. The complex connection relationship is an inherent characteristic of the distribution network, so the safe operation of the distribution network is the basic guarantee for people's normal life. [0003] In order to improve the reliability of the distribution network power supply and reduce the power outage time when the distribution network fails, it is necessary to find the contact relationship of each component in time when the fault occurs, so as to make ...
