Based on the purpose of accurately evaluating the operating status of series reactor type high impedance transformers,diagnose their fault levels,and construct an evaluation model for the operating status of series reactor type high impedance transformers.This model starts with the electrical,oil and gas,oil and chemical,and physical factors that affect the operation status of transformers,constructs an evaluation index system,and uses a subjective evaluation index combination weighting method based on objective correction to weight the index combination in an objective correction subjective way;By using a fuzzy comprehensive evaluation based operation status evaluation model,the membership degree of all weighted evaluation index factors is calculated.After analyzing the standard values of index factors,the scoring values of all index factors are calculated,and combined with the operation status level standards,the operation status level of transformers is determined.The results indicate that this model is accurate in evaluating the level of transformer operation status information and can achieve 100%consistent results.
