Embodiment Construction

[0016] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0017] An auxiliary decision-making method for power equipment fault handling based on the case reasoning method of the present invention obtains matching cases with similar characteristic parameters to the current working conditions by retrieving historical cases, revises the matching case solutions according to specific conditions, and then applies them to the current working conditions. On the basis of analyzing the characteristics of equipment cases, the method builds models based on equipment detection characteristics, organizes the classic case library of equipment fault maintenance, and uses the Euclidean distance theory to calculate the overall similarity between classic cases and target cases, and sequentially matches the target cases. Comparing similar classic cases, by listing the equipment fault handling methods of similar cases, pro...

Abstract

The invention discloses an electrical equipment fault aid decision making method based on case-based reasoning. The electrical equipment fault aid decision making method based on case-based reasoning comprises the following steps: firstly, preprocessing working condition data of electrical equipment to be subjected to fault handing so as to form description information according with a case specificity domain element structure; secondly, carrying out specificity domain distribution according to the description information, and finding a specificity domain corresponding to the description information in an existing case library; thirdly, respectively comparing the description information with every case in the specificity domain obtained in the step two, and respectively calculating similarities sim(Xi,Yi) of every subset in the description information and every case in the specificity domain; and fourthly, according to the calculated results, sorting the similarities of every subset in the description information and every case in the specificity domain from high similarity to low similarity so as to form a fault handing mode suggestion list of electrical equipment to be subjected to fault handling. The electrical equipment fault aid decision making method based on case-based reasoning has high stability and working efficiency.

Description

technical field [0001] The invention relates to the field of power equipment fault detection and decision-making, in particular to an auxiliary decision-making method for power equipment fault handling based on a case-based reasoning method. Background technique [0002] The power system has accumulated a wealth of equipment failure maintenance cases in the process of equipment operation and maintenance, and there are many classic cases that can serve as a good reference for equipment status assessment, fault diagnosis and maintenance decision-making. However, at present, when dealing with power equipment failures, experts in a certain field are mostly relied on based on the experience of the above-mentioned failure maintenance cases. Learn from previous experience in equipment failure maintenance. Moreover, the human factor in this method is large, and the stability of power equipment fault handling is not enough. Contents of the invention [0003] The purpose of the pr...
