The application of information management in the power system began to emerge since the end of 1970s. In recent years, many electric power enterprises in succession established the internal LAN, which can realize the information transmission by connecting the production and management systems. However the coordination and data transmission between the transformer substations are quite backward.This paper designed one kind of IM systems from the situation of transformer substation. It designed the system protocol and revised the internal structure of the system. With reference of other server designs, a proper design is put forward. For the high requirement of transformer substation IM system, a detailed design is made to ensure the secure transmission of the message and data and the making-friend mode is also improved. |
