Abstract

The invention discloses an automatic identification method for the topology of a low-voltage transformer area, belongs to the field of distribution automation in power systems, is applied to power distribution area monitoring and is realized based on a low-voltage power supply network. A branch terminal is arranged in a power distribution box in the power supply network, and the branch terminal collects feature information of an incoming line and an outgoing line in the power distribution box and transmits the feature information to an upper computer through a communication channel; and the upper computer automatically identifies area topology by utilizing correlation analysis according to the feature information. The invention has the beneficial effects that the topological relation between the transformer area distribution boxes is analyzed by utilizing the correlation, so that the reliability and the accuracy of judging the transformer area network topology are improved; incoming lines and outgoing lines of the distribution box are characteristic information acquisition points, and a plurality of pieces of characteristic information are acquired; the robustness is high, the influence of abnormal data can be effectively reduced, and the topology identification accuracy is improved; no influence is caused on a power grid and a user, and the safety is high.

Description

technical field

[0001] The invention belongs to the field of power distribution automation in electric power systems, is applied to the monitoring of distribution station areas, and particularly relates to automatically identifying the topological structure of low-voltage station areas by using the characteristic data information of incoming and outgoing lines in each branch box. Background technique

[0002] With the rapid development of my country's modernization process, the number of power users has increased significantly, and the power distribution system has become more and more perfect. In order to improve the reliability of power supply, it is of great significance to realize the intelligent management of power consumption in distribution network. In the distribution network, the premise of realizing the intelligent monitoring of station area distribution is that the topology structure of the station area is known. However, in the daily operation and maintenance man...
