Embodiment Construction

[0042] In order to make the technical problems to be solved in the present invention, technical solutions and advantages clearer, the following will be described in detail in conjunction with the accompanying drawings and specific embodiments, and the specific embodiments of the present invention will be described in detail as follows:

[0043] The present invention provides a method for determining the state maintenance time of power distribution equipment, the method flow is as follows figure 1 As shown, the condition-based maintenance of power distribution equipment in question is actually divided into health status grades based on the comprehensive deduction value of the equipment; after the entropy weight method is applied to the equipment status evaluation index, the health status cloud map of the equipment to be evaluated is generated through the cloud model. Then calculate the membership degree between the health status cloud of the equipment to be evaluated and each h...

Abstract

The invention provides a method for determining state maintenance time of power distribution equipment, belongs to the technical field of electric power engineering, and solves the problems that conventional equipment maintenance of a power distribution network is mostly periodic maintenance and after-event maintenance, the utilization efficiency of maintenance resources is low, and fault prevention cannot be performed for various equipment differences. According to the method, health state grading is carried out according to a device comprehensive deduction value, an entropy weight method isapplied to assign weight to a device state evaluation index, then a health state cloud chart of a to-be-evaluated device is generated through a cloud model, and then the membership degree between thehealth state cloud of the to-be-evaluated device and each health state grade cloud is calculated; and finally, inputting data such as the membership vector, the number of faults and the operation record into a long-term and short-term memory network for training to predict the next fault occurrence time of the to-be-evaluated equipment so as to reasonably plan an overhaul plan. Reasonable planningof an in-operation equipment maintenance plan is realized according to the predicted fault occurrence time, maintenance resources are effectively and reasonably utilized, and the equipment fault riskis reduced.

Description

Technical field: [0001] The invention belongs to the technical field of electric power engineering, and in particular relates to a method for determining the state maintenance time of power distribution equipment. Background technique: [0002] The maintenance of traditional equipment in the distribution network is mostly regular maintenance and post-event maintenance. The utilization efficiency of maintenance resources is low and it is impossible to prevent failures according to the differences of various equipment. Therefore, using the historical operation data and test data of power distribution equipment to carry out condition-based maintenance can not only avoid the blindness of maintenance, but also make full use of maintenance resources and improve maintenance efficiency. Invention content: [0003] The invention provides a method for determining the state maintenance time of power distribution equipment, which can solve the problems that the maintenance of traditio...
