Data conjoint analysis method applied to transformer oiling detection test

Abstract

The invention provides a data conjoint analysis method applied to a transformer oiling detection test, and belongs to the technical field of power transformation detection test data analysis and power equipment operation state evaluation. According to the method, a power transformation five-way detection test item is taken as a basis, and an insulating oil performance state is taken as an evaluation target, so that a data joint intelligent analysis method and strategy for evaluating the insulating performance of the insulating oil of the oil-filled transformer are provided. According to the method and the strategy, an oiling test data selection principle strongly associated with the insulating oil state of a single device and a decision factor determination method thereof are determined, an insulating oil performance index is calculated by establishing a transformer insulating oil performance index evaluation model, comprehensive evaluation of the insulating state of the transformer insulating oil is achieved to the maximum extent, and therefore, the health state of the transformer, especially the health state of the oil-filled transformer, can be evaluated more accurately.

Description

technical field [0001] The invention relates to the technical field of transformer oily detection, in particular to a data joint analysis method applied to a transformer oily detection test. Background technique [0002] With the development of the national economy, my country's power industry is facing more and more pressure. The pressure on power supply is huge. Every year, the economic losses caused by power equipment failures are as high as one trillion yuan. The hidden dangers cannot be found and analyzed in time during routine equipment inspections. Insufficient early warning and weak ability to judge hidden faults are the main reasons for equipment failures. [0003] The work efficiency of power transmission and transformation equipment inspection and testing in the power grid needs to be improved urgently. In terms of work mode innovation, there are still manual collection and analysis of test data, especially for power supply departments below the county level. Manua...

[0004] The healthy operation of the power transformer is related to the complete and stable operation of the power grid. It is a very important part of the power grid. Every year, the loss caused by the untimely and inaccurate judgment of the power transformer fault is very huge. Therefore, the health detection of the transformer is very important. Among them, the transformer insulation Oil insulation performance greatly affects the health of transformers, especially oil-filled transformers. In the past, the status evaluation of transformer insulation oil performance was only based on a single variable as a reference, but the effect was not ideal.
