Embodiment 1

[0046] A method for intelligent identification and auxiliary preparation of a regional power grid maintenance plan, comprising the following steps:

[0047] S1: Build an intelligent identification and auxiliary compilation system for regional power grid maintenance plans;

[0048] S2: Through the standard data resources in the power grid cyber-physical fusion system, build a standardized basic database, use fuzzy logic, and according to various constraints affecting intelligent reasoning, including mutually exclusive maintenance, simultaneous maintenance, sequential maintenance, unchangeable maintenance, The maintenance start time and maintenance duration form the maintenance knowledge base;

[0049] S3: Load grid equipment ledger information, maintenance knowledge base information, grid operation data and network parameter information into the regional grid maintenance plan intelligent identification and auxiliary compilation system;

[0050] S4: Read the grid maintenance pl...

Embodiment 2

[0057] The difference between the method for intelligent identification and auxiliary preparation of a regional power grid maintenance plan according to the embodiment of the present invention is different from that of the first embodiment: in S5, for the processing method of the maintenance time, the relevant formula is as follows:

[0058] Mutually exclusive overhaul constraints:

[0059] Simultaneous overhaul constraints:

[0060] Sequential inspection constraints:

[0061] Unchangeable maintenance constraints:

[0062] Maintenance start time constraints:

[0063] Maintenance Continuity:

[0064]

[0065] In the formula: x i and x j are the start maintenance time of the i-th and j-th equipment respectively; The number of days that the maintenance of the i-th equipment lasts; Indicates the unchangeable start time for maintenance of the i-th equipment; X i is the set of allowable maintenance time for the i-th equipment; T is the total number of maintena...

Embodiment 3

[0068] The difference between the method for intelligent identification and auxiliary preparation of a regional power grid maintenance plan according to the embodiment of the present invention and the first and second embodiments is that: in S7, the particle swarm algorithm includes the following steps:

[0069] (1) Initialize the particle swarm and set the relevant parameters of the particle swarm algorithm;

[0070] (2) Calculate the new velocity and position of the particle according to the velocity and position change formula;

[0071](3) Judge whether the termination condition is met, if so, stop the search and output the optimal solution, if not, go to (1).

[0072] Further, in S7, the intelligent diagnosis analysis and adjustment method for the maintenance data includes the following steps:

[0073] (a) Obtain the maintenance network model structure R and the maintenance knowledge base set N from the power grid cyber-physical fusion system, define the traversal node qu...

Abstract

The present invention discloses a regional power grid maintenance plan intelligent identification and auxiliary preparation method. It is the field of power maintenance technology. It includes the following steps: through the standard data resources in the power grid information physical fusion system, build a standardized basic database, and use fuzzy logic.According to the various constraints that affect intelligent reasoning, the maintenance knowledge base is formed;Equipment that needs to be maintained during the expiration; search for valid variables through the particle group algorithm to concentrate the basic data of each piece of maintenance, trigger the active rules mode, and use the regional power grid maintenance plan intelligent identification and auxiliary preparation system to complete the maintenance data of the maintenance data.Intelligent diagnosis analysis and adjustment.The present invention can effectively improve the rationality of the equipment maintenance plan, avoid repeated power outages, and improve the equipment utilization rate.

Description

technical field [0001] The invention relates to the technical field of electric power maintenance, in particular to a method for intelligent identification and auxiliary preparation of a regional power grid maintenance plan. Background technique [0002] With the continuous development of my country's power technology and power demand and the increasing scale of modern power grids, the number of power supply equipment and power transmission and transformation facilities is also increasing. The normal service of each power supply equipment is the guarantee for the high-quality operation of the power grid. However, the time from the beginning of use to the final scrapping of the equipment is limited, and equipment abnormalities and failures are the main reasons that affect its safe operation. Within the normal service period of the equipment, reasonable arrangement of equipment maintenance in a certain way can effectively reduce accidental failures, prolong the service life of...
