In the intelligent substation monitoring system solution, AOPRE-LINK8248, monitoring a and B dual networks, station control layer and system layer two-layer one network mode, the whole station one network to the end, change the bus differential direct mining and direct jump mode, and adopt network mining and network jump. Monitoring a and B dual networks ensure the stability and redundancy of data acquisition. The protection unit and merging unit of intelligent ied equipment are directly connected with the switch or protection monitoring equipment, and then uploaded to the station control layer through a and B to connect each server, monitoring host, motion workstation and remote control center, so as to realize the information integration and remote control of the whole station.
