Abstract

Aiming at the problem that a converter transformer is complex in structure and it is difficult to evaluate its condition accurately

a condition evaluation method based on DHGF algorithm is proposed for the converter transformer. The evaluation index sets and the corresponding weights are established

and the whitening weighting function

the weight matrix and the evaluation matrix are provided to construct a complete mathematical model. The condition of a real converter transformer is analyzed by using DHGF method

thus the condition level and the exact score are obtained. The results can reflect the real condition of the converter transformer

and can be used to support the next decision making of maintenance.
