Abstract

The invention discloses an intelligent self-healing method and system for a distribution network based on a topological graph. The method comprises the following steps: S1, establishment of the network topological graph; S2, grading of distribution network lines; S3, judgment of a fault section; and S4, handling of a fault. The system comprises a distribution master station and distribution substations, the distribution master station is connected with a distribution network automatic system and the distribution substations respectively, and the distribution substations are connected with a distribution terminal. By adopting the intelligent self-healing method for the distribution network based on the topological graph, the judgment rule on the fault section of the distribution network is upgraded by means of the topological graph, so that the distribution network automatic system can meet the requirements of complex distribution lines (i.e., radial multi-branch lines).

Description

technical field [0001] The invention relates to the technical field of distribution network automation, in particular to an intelligent self-healing method and system for a distribution network based on a topology map. Background technique [0002] With the progress of my country's modernization, the demand for electricity in all walks of life is increasing, especially in areas with rapid economic development, the industrial and civil loads are rising rapidly, and the number of power distribution systems and their equipment has increased significantly. The network structure of the system is becoming more and more complex, and the power supply operation mode is changing more and more frequently. There are higher and higher requirements for the stability of distribution network operation, the effectiveness of regulation, and the reliability of fault section judgment. Therefore, the accurate determination of the fault section of the more complex distribution network and the rapi...
