Distributed power supply monitoring system

The invention belongs to the technical field of electric energy management, and particularly relates to a distributed power supply monitoring system which comprises a master station layer, an execution substation layer, a centralized control unit layer and a terminal layer. The terminal layer is provided with a plurality of terminal ring networks, and each terminal ring network is connected with a plurality of terminals; a master station in the master station layer is connected with a plurality of execution substations in the execution substation layer; each execution substation is correspondingly connected with a plurality of centralized control units; and each centralized control unit is connected with the corresponding terminal ring network. Therefore, the problems that in the prior art, distributed power supply data and a regulation and control end system are not fully communicated, the obtained power supply information amount is small, and observability, measurability and controllability with the power g
