The invention discloses a polymorphic information comprehensive evaluation-based equipment quality control method. According to the method, on the basis of the integration of physical simulation-basedpower distribution equipment integrated detection and power distribution equipment on-line monitoring data, key indicators which reflect the operation quality of power distribution equipment are comprehensively analyzed and constructed, so that the overall operation quality of the power distribution equipment can be assessed objectively and accurately, and therefore, scientific and effective technical support can be provided for the operation quality control of the power distribution equipment. The key to assessing the operation quality of the power distribution equipment lies in the selection of operation quality assessment indicators and the establishment of an assessment model. In order to accurately assess the operation quality of the power distribution equipment, the ambiguity and randomness of the operation quality indicators of the power distribution equipment are comprehensively considered, a power distribution equipment multi-level operation quality assessment model that integrates a plurality of indicators is established to obtain the comprehensive operation quality assessment result of the power distribution equipment, and therefore, decision aids can be scientificallyand effectively provided for the quality control of the power distribution equipment.
