The invention discloses an energy management method based on data rule mining, relates to the technical field of train energy management methods, and is characterized in that the energy management method of a ground energy storage system based on data rule mining is provided according to a working condition identification method based on a K-means clustering algorithm. The overall working condition of the train in the power supply section can be accurately identified, and the dynamic adjustment of the charging and discharging voltage threshold of the energy storage system is realized according to the working condition identification result. Compared with a traditional energy management method based on a fixed threshold value or no-load voltage identification, the method can effectively absorb the residual regenerative braking energy of the train, fully utilizes the absorbed regenerative braking energy under the traction working condition, reduces the output energy of a transformer substation, and achieves the purposes of energy conservation and consumption reduction.
