The invention discloses a reclosing success rate correlation analysis method based on a disaster type and line information. The method comprises the steps of (S1) obtaining line trip information and extracting the disaster type and line parameters,(S2) completing the input of an original correlation analysis data set with the combination of a line reclosing success condition, (S3) setting a support degree threshold and using an Apriori algorithm to search a frequent item set, and (S4) with coincidence as rule consequent, and screening a strong correlation rule which satisfies requirement. According to the method, based on existing line trip data, the strong correlation rule related to a reclosing condition is extracted, the method can be used for optimizing a transmission line reclosing strategy, and the power grid safe and stable operation level and continuous reliable power supply ability are improved further.
