Digital converter station distributed fusion terminal time synchronization compensation method and device

The invention relates to the technical field of electric power communication, and discloses a digital converter station distributed fusion terminal time synchronization compensation method and device, and the method comprises the steps: S1, dividing priorities for the services of a digital converter station according to the types of the services; s2, initializing paths and time delays for the services after priority division by using a preset routing and spectrum allocation algorithm; s3, performing differential compensation by adaptively setting to-be-forwarded waiting real-time delay at the to-be-determined node, so that the time of a receiving end is synchronized, and performing path and frequency spectrum reconstruction according to the routing frequency spectrum of minimum compensation; s4, judging whether a permitted spectrum slot exists or not, if yes, executing the step S5, and if not, executing the step S2 in a re-routing manner; and S5, recording the transmission delay of the service, and calculatin
