Multistage control system of electric energy router

The invention discloses a multi-stage control system of an electric energy router. According to the invention, the synchronization signals are generated through the at least two controllers, the synchronization signals are sequentially forwarded to the port controller, the unit cluster controller group and the unit controller group according to the hierarchy, and then the synchronization signals are compensated when the synchronization signals are received through the unit controllers in the unit controller group. According to the invention, the synchronization signals are automatically generated through the at least two controllers, so that the controllers are subjected to redundancy configuration, the at least two controllers are standby for each other, and the synchronization signals are sequentially forwarded to the port controller, the unit cluster controller group and the unit controller group according to the hierarchy, so that the port controller and the unit cluster controller group can be synchroniz
