Model used for evaluating health state of electrical equipment

Abstract

The invention discloses a model used for evaluating the health state of electrical equipment, relates to the field of the electrical technology, can accurately evaluate the operation health state of the electrical equipment, and is convenient to carry out operations including reasonable use and maintenance, fault prediction, power distribution management and the like on the electrical equipment. The model used for evaluating the health state of the electrical equipment comprises an evaluation index module, a comment module, a fuzzy assessment module and a grey correlation module, wherein the evaluation index module comprises a plurality of state quantity indexes which affect the health state of the electrical equipment and the weight of each state quantity index; the comment module comprises a comment set and is used for assessing the health state of the electrical equipment; the fuzzy assessment module comprises a membership function established on the basis of the comment set, and is used for combining with the weight of each state quantity index through the membership function to carry out fuzzy assessment on the health state of the electrical equipment to obtain a fuzzy assessment conclusion; and the grey correlation module comprises a clear assessment standard established on the basis of the comment set, and is used for carrying out clear assessment processing on the fuzzy assessment conclusion to obtain an accurate health state evaluation result.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a model for evaluating the health state of electric equipment. Background technique [0002] With the rapid development of the economy, my country's power supply situation is becoming increasingly tense, and the economic losses caused by the failure of the power grid system throughout the country are as high as trillions. The main reason for the analysis is that the failure of the power grid system cannot be dealt with in time. [0003] Because my country's electric power enterprises have been implementing a unified national periodic maintenance system for a long time, its essential feature is based solely on time cycles. This mode obviously has bad problems such as not considering the actual condition of the equipment, lack of pertinence in the maintenance process, insufficient control of the equipment status, failure rules that do not conform to the life of the existing...

Problems solved by technology

This mode obviously has bad problems such as not considering the actual condition of the equipment, lack of pertinence in the maintenance process, insufficient control of the equipment status, failure rules that do not conform to the life of the existing power equipment, and negative effects such as excessive maintenance. , whether the maintenance system is perfect or not directly affects the reliability level of power equipment, so modeling the operating health status characteristics of power equipment is of great significance for its rational use and maintenance, fault prediction, and power distribution management.
