The invention discloses a power distribution automation graph model quality evaluation method, and belongs to the technical field of electric power and electric networks. The method is characterized by at least comprising the following steps of S1, establishing a power distribution automation graph model quality evaluation index system according to an SMART principle, wherein the index system comprises four second-level indexes including graph quality, model quality, graph model consistency and information accuracy; under the second-level indexes, performing subdivision to obtain third-level indexes and fourth-level indexes; S2, establishing evaluation standards of bottom layer indexes; by investigating and surveying actual conditions of power distribution automation graph model quality ofmultiple areas, giving out quantitative scoring standards of the fourth-level indexes; S3, determining weights of the indexes of all the levels by adopting an analytic hierarchy process; S4, performing graph model quality comprehensive evaluation by adopting a weighted average algorithm of balance degree correction; and S5, performing evaluation result display by adopting an improved radar chartmethod. The method reflects the influence of the index weights and the index balance degrees on an evaluation result, so that higher objectivity is achieved.
