Key Indicator System Establishment and Application for Transformer Condition Assessment Based on Hierarchy Grey Relation Analysis
摘要
Abstract
Aiming to solve the problems of various indicators and complex system structure in transformer evaluation system, we proposed the hierarchy grey relation analysis (HGRA) which is based on fault type to establish the key indicator system of transformer. First, the fault set and initial indicator set were selected for the power transformer. Then, the grey relational analysis (GRA) was proposed to get the comprehensive correlation degree (CCD) of inital indicator and fault type, so as to design the dynamic method for screening the key indicator. Finally, the support degree was introduced to check the rationality of the key indicator and the key indicator system was formed. The experimental results indicate that the evaluation results of the application of key indicator system to the transformer is consistent with the actual situation. A case analysis has proved the accuracy and practical application value of the key indicator system.关键词
