A self-healing method of distribution network master station based on electrical topology connection relationship

Abstract

The invention discloses a distribution network master station self-healing method based on the electrical topology connection relationship. By establishing a set of calculation rules, the system can automatically find errors in the topology connection relationship, automatically alarm, and automatically block the self-healing action strategy of the master station. Avoid the operation risk of the distribution network caused by the fault of the self-healing program caused by the error of the topological connection relationship. Compared with checking topology anomalies by humans, the present invention uses a computer system to obtain relevant data and perform analysis and calculation, which has extremely high efficiency and accuracy, and can effectively prevent the self-healing function of the distribution network main station from malfunctioning due to abnormal topological basic data relationships. Risks associated with grid operation.

Description

technical field [0001] The invention relates to the field of power system distribution network systems, and more specifically, to a self-healing method for a distribution network master station based on an electrical topology connection relationship. Background technique [0002] In modern society, the power supply reliability of the power grid, especially the power supply reliability of the distribution network, is getting higher and higher. Find fault points in the power grid in time, automatically calculate the optimal power recovery path according to the topological connection relationship of the distribution network, fault points, and fault status of the distribution network, and isolate the fault points of the distribution network through the remote control distribution automation terminal. Call back. In this process, the electrical topology connection relationship of the distribution network is the most basic information for fault isolation and power restoration. If...

Problems solved by technology

In the process of system interaction, it is easy to cause errors in the electrical topology connection relationship of the distribution network due to reasons such as failure to delete redundant electrical connection lines, failure to store equipment models, and failure to store connection points.

If the master station of the distribution network performs self-healing isolation and power recovery calculation on the basis of this electrical topology connection, it will cause the above-mentioned risk of self-healing action
