Apriori algorithm-based power grid fault determination method and storage medium

The invention discloses a power grid fault determination method based on an Apriori algorithm and a storage medium, standardized fault data is input into a pre-constructed fault diagnosis model to obtain a fault type, and the method comprises the following steps: iteratively screening by using the Apriori algorithm and a preset support degree in the fault diagnosis model to obtain a fault factor frequent item set in the standardized fault data; calculating a preset confidence coefficient in the fault diagnosis model; and sorting the fault factor frequent item sets by using a pre-established logic relation database between the fault factor frequent item sets and the fault types and a preset confidence coefficient in the fault diagnosis model to obtain the fault types. According to the method, historical fault data are scanned, fault-tolerant processing and generalization are carried out, the fault diagnosis model is established, the fault type is explored from the macroscopic perspective, and comprehensive ana
