Data synchronization method and device, equipment and storage medium

The embodiment of the invention discloses a data synchronization method and device, equipment and a storage medium, and the method comprises the steps: obtaining the storage path information of to-be-synchronized data, encrypting the storage path information according to a preset encryption method, and generating engineering data; sending the engineering data to a target substation corresponding to a substation where the to-be-synchronized data is located through a preset micro-service interface; and obtaining a data calling request generated by the target substation based on the engineering data, and sending the to-be-synchronized data to the target substation through a secure file transfer protocol according to the data calling request. By combining a micro-service mode and a safe file transfer protocol mode, data synchronization is completed on the premise that safe and economical operation of a power grid can be guaranteed, high-level transformer substations can manage and control data of all low-level tr
