Flexible DC power distribution network fault handling system and method based on end-side cloud collaboration

The invention relates to a flexible DC power distribution network fault handling system based on end-side cloud collaboration, and the system comprises an end-side device which is used for completing the recognition and disconnection of a fault line; the side device is used for completing analysis and processing of the fault data, sending a line on-off instruction to the end side device through wired transmission, and sending a line on-off state to the cloud server through wireless transmission; and the cloud server is used for receiving and summarizing the line on-off states uploaded by the side devices and visually displaying the line on-off states to a user, so that maintenance personnel can make a subsequent decision of closing the interconnection switch, and fault recovery work is completed. The invention also discloses a fault handling method of the flexible DC power distribution network fault handling system based on end-side cloud cooperation. The thought of distributed calculation is introduced, a la
