摘要 实现电力变压器状态评估是提高变压器运行可靠性,为状态维修提供合理决策的重要手段,长期使用的静态评估方法已经不适应现代输变电技术发展.针对模糊综合评估方法的缺点,应用基于物元理论的变压器状态综合评估方法,在对变压器指标进行量化的基础上,定性和定量的评估变压器的运行状态.同时采用改进的层次分析法不需要进行一致性检验,能够合理、快速地给出各指标权重,从而提高了评估的准确性.经实例分析证明,基于物元理论的变压器状态评估方法是合理和有效的. Condition assessment on power transformer is an important approach to improve reliability of transformer and provide proper decision-making for condition-based maintenance. For long, static assessment method used in the past has already not adapted to the development of modem electricity transmission and distribution technology. So based on the deficiency of fuzzy synthetic assessment method, matter-element synthetic assessment method is introduced. The method can evaluate transformer condition not only in quality but also in quantity. Because each index weight can be given fairly and fast through improved analytic hierarchy process, which need not carry on consistency chec accuracy of assessment can be improved. Examples analysis has proved that assessment method of power transformer condition based on matter-element theory is rational and effective.
