Abstract

Provided is a communication system used for an electric power system, and provided with a plurality of communication devices for transferring a packet including identification information of a transfer destination by wireless communication. The communication device receives a specific packet that is the abovementioned packet including specific type information regardless of the identification information, and when receiving the specific packet, performs discard processing for discarding the packet including type information different from that of the specific packet during a predetermined period, and the communication device as the transfer destination transfers the received specific packet including identification information of another transfer destination by wireless communication.
