摘　　要：基于准确评估串联电抗器式高阻抗变压器运行状态的目的,诊断其故障级别,构建串联电抗器式高阻抗变压器运行状态评估模型。此模型从影响变压器运行状态的电气类、油气类、油化类、物理类因素着手,构建评估指标体系后,利用基于客观修正主观的评估指标组合赋权方法,以客观修正主观的方式,为指标组合赋权;通过基于模糊综合评估的运行状态评估模型,计算全部赋权后评估指标因素隶属度,分析指标因素标准值后,计算全部指标因素评分值后,结合运行状态级别标准,判断变压器运行状态级别。结果可得,此模型对变压器运行状态级别信息评估结果准确,可得到100%一致的结果。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.
