High-safety communication system of intelligent substation

The invention discloses a high-safety communication system of an intelligent substation, and belongs to the field of communication systems of intelligent substations. According to the high-safety communication system of an intelligent substation, when a network fault occurs in a substation module, monitoring data is reserved in a data storage module, after the network is recovered, the monitoring data is uploaded to an upper-level control terminal, data monitoring is continued, when a lower-level control terminal cannot process the operation problem of a current substation module, an electrical connector is disconnected, so that the connection between the upper-level control terminal and the lower-level control terminal is disconnected, the upper-level control terminal is maintained by maintenance personnel, therefore, the lower-level control terminal and the upper-level control terminal in the substation module realize information interaction through a network and are connected through the electrical connect
