The invention relates to a substation information pushing system and belongs to the field of intelligent substation information service management. The system comprises an information processing module, an information pushing module and a network sniffing module which is configured according to a substation communication protocol. The network sniffing module is used for obtaining information sent to a monitoring master station by devices of a substation in real time and storing the obtained information in a system original message buffer area. The information processing module is used for carrying out filtering, classification and format conversion on the information stored in the system original message buffer area according to a message type and message protocol feature characters and then adding the information to corresponding pushing queues. The information pushing module is used for reading the information from the pushing queues according to information subscription lists customized by different clients and pushing the information to the corresponding clients. According to the system provided by the invention, related device information focused by manufacturers or related departments is pushed to the corresponding clients accurately in real time with pertinence, and the method for learning the operation condition of the devices timely by the manufacturers and the operation and maintenance departments is provided.
