Zusammenfassung:The invention discloses a cloud matter element-based extra-high voltage converter transformer quality grading method and system. The method comprises the steps of determining a to-be-evaluated matter element and a standard cloud of an extra-high voltage converter transformer; the standard cloud comprises a plurality of state levels; determining a correlation degree between the to-be-evaluated matter element and each state level in the standard cloud; based on the correlation degree, calculating a comprehensive correlation degree corresponding to the to-be-evaluated matter element and each state grade; and evaluating the comprehensive correlation degree based on a maximum membership degree principle, and determining the quality grade of the extra-high voltage converter transformer based on an evaluation result. 本发明公开了一种基于云物元的特高压换流变压器质量分级方法及系统，其中方法包括：确定特高压换流变压器的待评物元以及标准云；所述标准云包括多个状态等级；确定所述待评物元与所述标准云中的各状态等级之间的关联度；基于所述关联度，计算所述待评物元与各状态等级对应的综合关联度；基于隶属度最大原则对所述综合关联度进行评价，基于评价结果，确定特高压换流变压器质量分级。
