Abstract

The invention discloses a transformer performance evaluation method, and solves the problem that subjective factors are taken as a basis to analyze problems and an objective theoretical basis is lacked in the prior art. Firstly, a transformer performance evaluation key index system is constructed, then weights of indexes are obtained through an analytic hierarchy process, finally, a quantitative correction scoring function is introduced to obtain scores of all the indexes and the overall performance of the transformer, the fault condition is analyzed according to the scores, the performance level of the transformer is divided, and the maintenance level is recommended. According to the transformer performance evaluation method, all parts and parameter sources of the transformer are comprehensively considered, the transformer performance scoring function is reasonably given, certain practicability is achieved, and the technical problems that in a transformer performance evaluation system, the number of indexes is large, and the indexes are connected and influenced mutually are solved.

Description

Technical field

[0001] The invention belongs to the technical field of performance failure evaluation, and specifically relates to a transformer performance evaluation method. Background technique

[0002] Transformers are the core electrical equipment for power transmission in the power grid. With the development of the power grid, the performance requirements of transformers are getting higher and higher. For the safe and stable operation of the power grid, it is very necessary to perform transformer performance evaluation. With the development of transformer monitoring technology, there are many measured indexes that characterize the performance of transformers, and there is a relationship between indexes and between indexes and performance, which makes the performance evaluation index system very complicated. How to correctly analyze and process the obtained data and apply it to the transformer performance evaluation method is a hot issue currently studied.
