A two-stage optimization method for live working paths in distribution networks

Abstract

The present invention relates to a two-stage optimization method for live work paths in a distribution network, comprising: Step S1: Obtain the work plan or urgent task requirements for live work in the next cycle, and collect task information of operating points according to the plan or requirements; Step S2: Perform weekly According to the combination of the previous operation tasks, the operation points are divided into several areas according to the principle that the operation points in the same area (one-to-one correspondence between areas and working days, the same below) are as close as possible in geographical location and have the same working day time limit requirements; step S3 : Carry out rolling optimization of the day-ahead operation path and update the day-ahead urgent task requirements. For a certain area, the optimal operation path for this area is calculated with the goal of minimizing the mileage of all vehicles required to complete the task of the operation point in the area. Compared with the prior art, the present invention adopts a two-stage optimization method, first decomposing the work tasks into working days, and then determining the driving path of the working vehicles on each working day, and solving the problem of working plan preparation for live work in the distribution network in stages.

Description

technical field [0001] The invention relates to the maintenance technology for the uninterrupted operation of the distribution network, in particular to a two-stage optimization method for the live operation path of the distribution network. Background technique [0002] Live work refers to the maintenance, overhaul or transformation of lines and equipment of various voltage levels in the power grid without power failure, which is of great significance for improving the service level and economic benefits of power supply enterprises and reducing power failure losses of users. In recent years, with the improvement of users' requirements for power supply reliability, distribution network maintenance is gradually developing in the direction of "removing power outages". Live work has developed into an important technology for distribution network maintenance and overhaul due to its advantages of reducing power outages or even eliminating the need for power outages. means.

AI Technical Summary

Problems solved by technology

The distribution network line distribution is characterized by "multiple points and wide areas", so the working locations of distribution network live operators are scattered geographically, and the geographical distance between different operating points is far away, and the conversion efficiency between operating points becomes a limit to the improvement of work efficiency important factor

The preparation of the work plan for power distribution liveline work determines the work path, but there is no effective work plan preparation method at present. It is still relying on manual experience to try to arrange the same work trip on the same day for some relatively close work points. Distributed on tens of thousands of base towers with hundreds of distribution network lines in the city, it is impossible for planners to accurately grasp the location information of these locations, and the number of tasks involved can reach dozens of items at the same time, which is obviously based on manual information acquisition and processing If the computing power is not up to the requirements, the traditional experience cannot realize the optimization of the work plan, resulting in a lot of waste of time and cost, which greatly reduces the efficiency of on-site work

In particular, the insulated bucket arm truck is currently the main insulated carrying tool and vehicle for carrying out live work in the distribution network. Its fuel consumption is huge, and the driving cost caused by unreasonable working paths is very significant.
