Abstract

The invention discloses a self-healing method and device for a power distribution network, electronic equipment and a storage medium, and the method comprises the steps: obtaining fault information of a domain type protection system of a power distribution network station and line structure information of the power distribution network, recognizing the fault information, obtaining a fault recognition result message, and carrying out the self-healing of the power distribution network based on the fault recognition result message. And in combination with the line structure information, screening to obtain a target interconnection switch, and switching on the target interconnection switch by applying a power distribution network checking strategy to recover normal power supply of a non-fault point line. The technical problem that a traditional power distribution network self-healing method cannot give consideration to the fault isolation efficiency and the self-healing speed at the same time is solved, and the power supply reliability of the power distribution network is improved.

Description

technical field [0001] The present invention relates to the technical field of power supply restoration of power distribution network, in particular to a self-healing method, device, electronic device and storage medium of power distribution network. Background technique [0002] At present, the structure of the distribution network is becoming more and more complex, there are many types of users, and the requirements for the reliability of power supply are also increasing. more frequently. In view of the above characteristics, the current distribution network protection method is realized through differential coordination, with long protection trip time and single protection method, unable to adapt to the dynamic change of power, and unable to fully consider the influence of distributed power sources on line circuit current. In principle, it is impossible to At the same time, taking into account the efficiency of fault isolation and self-healing speed, it cannot effectivel...
