Embodiment Construction

[0024] The decision-making method of transformer condition maintenance of the present invention is described in detail below in conjunction with accompanying drawing and embodiment, as figure 1 shown, including the following steps:

[0025] Step S1: Read relevant data of each transformer, wherein the relevant data includes routine test data, online monitoring data and manual inspection data;

[0026] Step S2: Using the triangular fuzzy number analytic hierarchy process, perform fuzzy analytic hierarchy process on the relevant data to obtain an optimal transformer maintenance decision-making scheme.

[0027] The invention can solve the problems existing in the existing method, provides a method of establishing a power transformer maintenance decision-making model by using the triangular fuzzy number analytic hierarchy process, and relatively scientifically decomposes the complex problem of power transformer maintenance decision-making.

[0028] In order to clarify the decision...

Abstract

The invention provides a decision-making method for the state overhaul of transformers. The method comprises the following steps: (1) reading data relative to each transformer, wherein the data comprises routine experimental data, on-line monitoring data and manual inspection data; (2) utilizing the analytic hierarchy process of a triangular fuzzy number to perform a fuzzy analytic hierarchy process for the relative data, thereby acquiring the optimal overhaul decision-making scheme for the transformers. The invention also provides a decision-making system for the state overhaul of the transformers, owing to the decision-making method, the flexible decision of the plurality of transformers can be scientifically analyzed and solved, various influence factors can be integrated to serve as a decision-making index, quantification calculation is well carried out, the indefinability and the fuzziness of the decision-making factors are reasonable processed, the decision to overhaul the state of the transformers is scientific and reasonable, the practical demand for the decision to overhaul the transformers is met, and the execution of the overhaul work of the state of the transformers is facilitated.

Description

technical field [0001] The invention relates to a decision-making method and system for condition maintenance of a transformer, belonging to the field of electric power engineering. Background technique [0002] Experts, scholars and engineers at home and abroad have conducted in-depth research and engineering practice on the decision-making technology of condition-based maintenance of electrical equipment, and have achieved corresponding results. The common decision-making methods are as follows. [0003] (1) Multi-stage decision-making and Markov decision-making: [0004] These decisions are divided into several stages according to the sequence, and the multi-stage decision-making problem usually adopts the dynamic programming method. The series of decision-making cannot be determined in advance, but according to the situation in the process of implementing the decision-making, this kind of decision-making problem is called sequential decision-making. [0005] (2) Multi-...
