Problems solved by technology

[0003] At present, most of the research on operation and maintenance scheduling focuses on the optimization of workload and load loss, and lacks the assessment of the safety risk of operation and maintenance planning. When considering complex problems with multiple constraints and multiple objectives, these methods have limitations. Weaknesses of difficulty in model extraction, difficulty in implementing algorithms, and large amount of computation

Abstract

The invention provides a maintenance risk based power equipment operation and maintenance schedule optimizing method. The method includes a step S1 of collecting history operation and maintenance data; a step S2 of establishing an equipment operation and maintenance schedule optimizing target model according to the history operation and maintenance data; a step S3 of setting constraint conditionsfor operation of the equipment operation and maintenance schedule optimizing target model; a step S4 of grouping prior operation and maintenance schedules and adopting a dynamic planning method for solving the equipment operation and maintenance schedule optimizing target model; a step S5 of comparing the minimal costs of operation and maintenance work of each group and taking the operation and maintenance work of the group with the minimum cost as the optimal schedule scheme and executing the scheme. According to the invention, the optimal operation and maintenance schedule plan can be obtained, so that the operation and maintenance scheduling efficiency is improved, the scheduling practicability is ensured, safety and stability of a power grid is enhanced and operation and maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of equipment operation and maintenance, in particular to a method for optimizing operation and maintenance plans of electric equipment based on maintenance risks. Background technique [0002] Power equipment is the main form of assets of power companies because of its high value, large quantity, and high reliability. The operation and maintenance of power equipment refers to the daily maintenance and inspection of equipment by power companies. According to the current work form, the operation and maintenance of power equipment mainly includes professional work such as inspections of electrical equipment, regular maintenance, and preventive tests. Various types of work are divided into various subdivision types. For example, inspections are divided into daily inspections and night inspections. , Professional inspection and special inspection. The classification criteria include factors such as inspection requirement...
