Problems solved by technology

At present, domestic power supply companies are vigorously promoting condition-based maintenance demonstration projects. However, due to the high requirements of condition-based maintenance on technology and economy, the implementation of condition-based maintenance in distribution networks is not complete, and different maintenance methods coexist. Moreover, it can be foreseen that the full implementation of condition-based maintenance will take a long time

Embodiment Construction

[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, its specific implementation will be described in detail below in conjunction with the accompanying drawings:

[0035] Examples of the invention: see figure 1 , a distribution network maintenance decision-making optimization method, comprising the following steps: Step S1, read in the grid data of the distribution network and the information of each device in the distribution network;

[0036] Step S2, initialize the position and velocity range of each particle, randomly generate a particle swarm, each particle represents a legal overhaul plan, that is, a plan that does not violate the constraint conditions, and initialize the global optimal and individual optimal;

[0037] Step S3, updating the position and velocity range of the particle swarm to generate a new generation of particle swarm;

[0038] Step S4, analyze the legality of each particle in the new ...

Abstract

The present invention discloses an optimization method for an overhauling decision of a power distribution network. A particle swarm optimization algorithm is used for performing optimization searching; each particle in a swarm represents an overhauling scheme; and change of overhauling starting time of any device is considered to be a new scheme, so that the overhauling decision of the power distribution network has advancement and pertinence.

Description

technical field [0001] The invention relates to a decision-making optimization method for distribution network maintenance. Background technique [0002] As one of the key technologies for building a strong smart grid, condition-based maintenance overcomes the shortcomings of insufficient and excessive maintenance of traditional planned maintenance to a large extent, and has achieved good results. At present, domestic power supply companies are vigorously promoting condition-based maintenance demonstration projects. However, due to the high requirements of condition-based maintenance on technology and economy, the implementation of condition-based maintenance in distribution networks is not complete, and different maintenance methods coexist. And it can be foreseen that the complete implementation of condition-based maintenance will also take a long time. [0003] The research on condition-based maintenance at home and abroad mainly focuses on two aspects: equipment conditi...
