Power distribution network fault evaluation and scheduling method and system

Abstract

The invention discloses a power distribution network fault evaluation and scheduling method and system, and the method comprises the steps: constructing and obtaining an urban digital distribution network topological map based on a geographic information system and distribution network construction information; positioning fault point distribution information based on the distribution network terminal monitoring data and the marketing data; planning an inspection path; photogrpahing images of the routing inspection path along the way and fault points by the unmanned aerial vehicle group; inputting the shot image into a pre-trained convolutional neural network, and evaluating the affected condition and the traffic condition to obtain an evaluation result; constructing and obtaining an optimal scheduling model according to a predetermined strategy; solving the optimal scheduling model by utilizing a simulated annealing algorithm to obtain an optimal scheduling scheme; and scheduling according to the optimal scheduling scheme. According to the method, after an extreme meteorological event occurs, a fault point can be rapidly positioned and a disaster situation can be evaluated, and anoptimal first-aid repair scheduling scheme and a first-aid repair progress monitoring function are provided.

Description

Technical field [0001] The invention belongs to the technical field of power distribution network fault evaluation and emergency repair dispatching, and particularly relates to a method and system for evaluating and dispatching power distribution network faults. Background technique [0002] Emergency repairs of the distribution network after extreme weather events such as typhoons, waterlogging, storms, ice and snow are an important part of the related work of the distribution network. When the distribution network fails, it will bring economic losses to the normal production of users and endanger the safe operation of the power grid. Traditional distribution network fault repairs have problems such as slow response, uneven distribution of repair resources, and inadequate monitoring of repair progress. In order to improve the power supply quality of the distribution network and reduce the economic losses caused by extreme weather events, it is necessary to locate the fault poin...

Problems solved by technology

[0003] The current distribution network emergency repair dispatching function is single, and generally only has the function of accepting fault acceptance and dispatching fault emergency repairs. After a fault occurs, it takes a long time to be discovered and confirmed, and relevant personnel cannot be dispatched in time to inspect the disaster situation on the spot, making it difficult to comprehensively and quickly Assess the disaster situation of the fault point after the disaster, so the existing resources cannot be effectively used to give the optimal emergency repair scheduling plan

In addition, when implementing the emergency repair plan, the traditional method cannot effectively and intuitively monitor the emergency repair progress in real time, and it is not convenient for emergency repair personnel to guide online and adjust the plan in time, resulting in low emergency repair efficiency
