Electrification detection data processing method based on data mining technology

Abstract

The invention belongs to the technical field of data mining in information technologies, and relates to an electrification detection data processing method based on a data mining technology, in particular to a state analysis technology and method for a transformer, a breaker, an arrester and others in electrical equipment. The processing method includes the steps that according to maintenance lag existing in traditional state maintenance of the electrical equipment and redundant work of overmuch planned maintenance, and a data mining state analyzing model with a rough set and a decision-making tree combined is built and combined with an existing electrical equipment state maintenance system to build the electrification detection data processing system based on the data mining technology. The rough set and the decision-making tree fusion technology is applied to state data analysis of the electric equipment, according to existing state judgment standards, state data of an over 35 KV transformer, an SF6 breaker and other electric equipment are preprocessed, Gini coefficient indexing, attribute reduction, threshold value selection and other steps are performed on attributes, state analysis is performed on the basis, meanwhile a work state table is formed, and a corresponding processing scheme is given.

Description

technical field [0001] The invention belongs to the technical field of data mining in information technology, and in particular relates to a technology and method for real-time data analysis and processing of live equipment such as transformers, circuit breakers, and lightning arresters in substations. Background technique [0002] Electric power is the basic industry of national industry, which is related to the sustainable development of national economy. With the development of modern society and economy, the huge demand for energy has promoted the rapid development of the power industry, making the power system develop towards large-capacity, ultra-high voltage and cross-regional directions. However, with the increase of system capacity and the expansion of power grid scale , the impact of power equipment failure on people's production and modern life is increasing, and the stable economic operation of the system is also increasingly demanding, and a strong guarantee for...

Problems solved by technology

For the overhaul of those equipment in good condition, especially the disassembly and overhaul, it will affect its performance in the slightest, and reduce its life in the worst case.

As a result, unnecessary power outage losses and waste of manpower, material resources and financial resources have been caused, and even maintenance failures have been caused.

[0008] The main reason for this defect lies in the insufficient evaluation of the status and operation of power equipment. The status evaluation of power equipment is a multi-attribute decision-making problem. Comprehensive evaluation index system

The formulation of power equipment maintenance plan contains many uncertain factors. It is a multi-objective and multi-constraint optimization problem. There are difficulties in optimization such as multi-dimensional, mixed integers, and nonlinearity.
