Scientific evaluation of the main transformer equipment suppliers is the premise to ensure the cost control and safe operation of the power grid. Based on the analysis of various factors affecting the main transformer equipment supplier, the evaluation index of the main transformer equipment supplier is constructed. Considering the fuzziness of the evaluation index, the index weight is determined by AHP, and the evaluation model of main transformer equipment supplier based on fuzzy comprehensive evaluation is established. The example calculation shows that the fuzzy comprehensive evaluation method can fully reveal the evaluation index information and reflect the actual situation of main transformer equipment suppliers scientifically and reasonably.
