Abstract
Description
Technical Field
[0001] The invention relates to a method and system for planning a fault recovery path for electric power equipment, belonging to the technical field of electric power fault recovery. Background Art
[0002] The power system, especially the distribution network, is easily affected by natural disasters (such as typhoons, floods, earthquakes, etc.) and human factors (such as equipment failures, operational errors, etc.), resulting in large-scale power outages, which ultimately affect people's production and life. Therefore, it is necessary to speed up the repair and restoration of the distribution network. Traditional fault recovery methods usually rely on expert systems and heuristic algorithms. These methods require a lot of expert knowledge and experience, have high computational complexity, and poor real-time performance;
[0003] The invention patent with announcement number "CN115800270B" discloses a method and device for coordinated restoration of power and communication in a distribution network, wherein the method includes the following steps: dividing the area to be restored into a number of first-level areas to be restored and second-level areas to be restored; taking the first-level area to be restored where the faulty base station is located as the emergency communication restoration area, and determining all emergency communication restoration areas where the faulty base station is located; calculating the restoration return of the faulty base station in each emergency communication restoration area according to the power parameters of the second-level area to be restored and the communication parameters of the emergency communication restoration area, and restoring the communication failure of the emergency communication restoration area in the order of restoration return from large to small; constructing a two-layer optimization model of power communication in the area to be restored with the overall goal of quickly restoring power supply to important load level areas; solving the two-layer optimization model of power communication using a depth-first traversal path search algorithm to determine the final repair plan; the method can significantly shorten the emergency repair time of the distribution network after a disaster and reduce the power outage losses of the distribution network.
[0004] However, the above scheme does not take into account the aging degree of power equipment and the failure of communication links. Power equipment with a high degree of aging may be the key nodes in the distribution network. Once these nodes fail, it may cause large-scale power failures. Therefore, they need to be restored as a priority. At the same time, the stability of the communication link also affects the transmission efficiency of the communication and the overall stability of the distribution network. All communication links should also be considered in the repair plan. Summary of the invention
