Problems solved by technology

At present, when formulating a power outage maintenance plan, resources and tasks cannot be allocated globally, and resource scheduling for power outage inspections has poor benefits, low efficiency, and high costs
[0004] In practice, when the fitness value of a power outage state greatly exceeds the average level, the local convergence brought about has an important negative impact on the overall resource allocation efficiency

[0036] In conjunction with accompanying drawing, the present invention is described in detail:

[0037] A control method for a comprehensive power outage maintenance plan, figure 1 It is based on the power grid implementation state data power outage maintenance optimization flow chart. figure 2 A flow chart of an efficient immune genetic algorithm for solving resource scheduling problems.

[0038] 1) Track and monitor the equipment status, input equipment status data through comprehensive online monitoring and live detection, compare with the data stored in the central processor, and determine whether maintenance is required.

[0039] Read in the real-time status data of regional equipment in the power grid. Data information includes status parameters and real-time data of power grid equipment, and calculates power outage maintenance task requirements and costs. The calculation results divide the device status into four types: "normal status", "attention status", "abnormal...

Abstract

The invention discloses a control method of an integrative interruption maintenance plan. The control method comprises the steps of tracking and monitoring equipment state, comparing with data stored in a central processing unit (CPU) by integrally online monitoring and live detecting input equipment state data, and determining whether the maintenance is necessary, wherein the CPU obtains a resource scheduling fitness matrix according to the maintenance state and the fitness relation between the interruption maintenance benefit, efficiency in a maintenance resource number determining region and the interruption maintenance task; the CPU determines an optimized objective and constraint conditions according to an interruption rule and target setting; the CPU encodes the task set and randomly generates an antibody; and the CPU adopts calculates by adopting an efficient immune genetic algorithm so as to obtain the optimization result in global convergence. The global co-allocation of the resource and the task in the maintenance plan is realized, the resource scheduling benefit and efficiency of the interruption inspection are improved, and the time, cost and price are reduced.

Description

technical field [0001] The invention relates to a method for selecting a power grid implementation maintenance plan, in particular to a control method for a comprehensive power outage maintenance plan based on an efficient immune genetic algorithm. Background technique [0002] The decision-making of comprehensive outage maintenance plan is an important aspect of efficient management of the power grid and ensuring the reliability of the power grid in the process of power outage planning. [0003] In a power grid with a network topology structure, topology analysis should be carried out for each power outage maintenance plan one by one to determine the power outage scope of each power outage maintenance plan, so as to reduce the overall number of repeated power outages. Therefore, the outage maintenance planning decision is a large-scale, multi-constraint, multi-objective and discrete control variables and other characteristics. At present, when formulating a power outage ma...
