XGBoost-based electric power secondary equipment defect degree evaluation method

Abstract

The invention discloses an XGBoost-based electric power secondary equipment defect degree evaluation method, which comprises the following steps of: firstly, acquiring and arranging related defect data of electric power system secondary equipment, and performing a series of preprocessing work such as duplicate removal, abnormal value filtration, missing value removal and the like on the acquired historical defect data of the electric power system secondary equipment; then carrying out association rule mining on the processed data based on an Apriori algorithm; screening out features having strong association rules with the defect degree of the secondary equipment of the power system to establish a feature index set, performing feature and label coding on index data, and after data grouping, performing training and parameter optimization on an XGBoost model by utilizing data of a training set and a test set respectively; and finally, achieving accurate classification of the defects of the secondary equipment of the power system by using the trained classification model. Maintenance personnel can be well assisted in maintenance and management of the equipment.

Description

technical field [0001] The invention belongs to the state evaluation and defect classification technology of electric equipment, and in particular relates to an XGBoost-based evaluation method for the defect degree of electric secondary equipment. Background technique [0002] The secondary equipment of the power system is one of the key equipment for the safe and stable operation of the smart substation, and its operating status is related to the reliable power supply of the power system. In recent years, with the rapid development of science and technology, the scale of the power system has continued to expand, and the number of secondary equipment in the power system has also grown by leaps and bounds. Personnel have brought a considerable workload, and at the same time brought risks to the operation of the power system. The operation, maintenance and control level of secondary equipment needs to be improved urgently. [0003] The defect rate of secondary equipment is in...
