The invention discloses a correlation analysis-based power distribution network power supply evaluation method and system, and the method comprises the steps: obtaining a plurality of evaluation index data of a plurality of power distribution regions of a power distribution network according to a power grid evaluation index, and obtaining a first to-be-evaluated index sequence; wherein the power grid evaluation indexes comprise a power grid margin index, a power grid coordination index, a power grid reliability index and a power grid safety index; performing correlation analysis processing on the first to-be-evaluated index sequence to obtain a second to-be-evaluated index sequence; and performing power supply quality evaluation on the second to-be-evaluated index sequence to obtain a power distribution network power supply evaluation result. The power supply quality of the power distribution network is quantitatively evaluated, and the evaluation accuracy of the power distribution network is improved. 本发明公开了
