Embodiment Construction

[0026] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings. A method for automatic identification of distribution network topology based on node electrical distances specifically includes the following steps:

[0027] Take the 9-node topology network with ring structure as an example, such as figure 1 as shown,

[0028] Step 1: According to the relevant data of the distribution network design scheme, obtain the electrical distance D between each node in the distribution network mn ;

[0029] Step 2: Select any power input node as the search starting node N 1 , calling the relevant data obtained in step 1, can directly calculate the electrical distance between the other nodes in the distribution network and the starting node, and number them in ascending order according to the distance, and continue to number other nodes after completion.

[0030] Step 3: Search from the starting node to the number o...

Abstract

The invention belongs to the field of power distribution network automation, and particularly relates to a power distribution network topology automatic identification method based on a node electrical distance. Aiming at the problems of various distribution network branches, messy wiring and difficulty in real-time management, the invention provides the power distribution network topology automatic identification method based on the node electrical distance. The method comprises the following steps: firstly, obtaining electrical distances among nodes in a distribution network according to relevant data of the distribution network; selecting any input node in the power distribution network as a starting node, calculating the electrical distance between each node and the starting node, numbering the electrical distances according to an ascending sequence and determining the corresponding node number; obtaining the radiation topology of each node in the power distribution network by judging the relationship between the initial node and the electrical distance values of the two nodes; and performing supplementary judgment on the obtained radiation topology to finally obtain a global topology structure of the power distribution network. The power distribution network topology automatic identification method based on the node electrical distance is simple, reliable and low in cost.

Description

technical field [0001] The invention belongs to the field of distribution network automation, and in particular relates to a distribution network topology automatic identification method based on node electrical distances. Background technique [0002] As a terminal network directly facing the user layer in the power system, the importance of the distribution network is obvious. Distribution network automation refers to the use of modern electronics, computers, communications and network technologies to integrate online and offline data, distribution network data and user data, power grid structure and geographic graphics. Constitute a complete automation system to realize the modernization of monitoring, protection, control, power consumption and distribution management of the distribution network and its equipment under normal operation and accident status. Distribution automation can improve power supply reliability, improve user service quality, reduce loss and save ene...
