Problems solved by technology

In this maintenance mode, it is easy to make unnecessary maintenance to the power equipment in good health. If the power equipment has not yet had a health problem, it will be shut down for maintenance or equipment replacement. This method will inevitably lead to Huge waste of human, material and financial resources
At the same time, the current regular maintenance system still has a c

Embodiment Construction

[0042] The invention will be further described below in conjunction with the accompanying drawings and specific implementation examples. If only the weight coefficients are used for evaluation, the determination of the weight will contain a relatively large subjectivity component, and the change of the matrix order and the difference of subjective thinking will greatly interfere with the evaluation results, thereby affecting the accuracy of the evaluation. And fuzzy mathematics can unfold a multi-indicator object in one-dimensional space to realize objective comprehensive evaluation. Therefore, using the method of fuzzy mathematics to modify the weight coefficient by introducing the fuzzy membership function can effectively eliminate the influence of matrix order and subjective thinking on the calculation of weight results, so as to ensure the objectivity and accuracy of the state evaluation results.

Abstract

The invention provides an active maintenance-oriented power equipment health state evaluation method, which comprises the following steps of: firstly, acquiring state quantity index data of any power equipment in a power system, calculating the membership degree of each state quantity index through a fuzzy distribution membership degree function, and constructing a paired comparison matrix. According to the method, the maximum characteristic value and the initial weight of each corresponding index are calculated, consistency verification is performed on the maximum characteristic value and the initial weight, and meanwhile, an objective correction coefficient is introduced to correct the initial weight coefficient, so that the influence of subjective factors in determining the initial weight distribution is eliminated, and the requirements of system operation on the aspects of safety, reliability, economy and the like can be better considered; an equipment health state research basis is provided for researching an active maintenance strategy of power equipment; the power equipment is kept in an excellent health state in the full-life service cycle, and the optimal service performance of the equipment is maintained by using a low-cost and high-efficiency maintenance strategy, so that the safe, reliable and economical operation of a power system is ensured.

Description

technical field [0001] The invention relates to the technical field of power equipment state evaluation, in particular to an active maintenance-oriented power equipment health state evaluation method. Background technique [0002] For a long time, power system workers mainly judge the health level of power equipment through regular maintenance measures to ensure the good operation of power equipment. Its content mainly includes preventive test, overhaul, minor repair and other methods. Under such a maintenance and management system, the power equipment is regularly overhauled regardless of the state of the power equipment. In this maintenance mode, it is easy to make unnecessary maintenance to the power equipment in good health. If the power equipment has not yet had a health problem, it will be shut down for maintenance or equipment replacement. Cause huge waste of manpower, material resources and financial resources. At the same time, the current regular maintenance sys...
