Realization of Electric Power Communication Network

The data transmission channel is the carrier of data collection and information interaction, and its function is mainly to realize the communication between the substation collection terminal and the master station. In order to ensure the stability of data transmission, the transmission channel between the collection terminal of the sub-station and the main station adopts the regional power dispatch data network or the Inner Mongolia provincial power dispatch data network, and the communication protocol adopts a variety of expanded versions of the 102 protocol. The dispatching data network adopts IPover SDH technology for networking and transmission based on optical cable channels. The reliability and safe transmission of the dispatching data network affect the safe and stable operation of the power grid. Therefore, this paper studies and analyzes the safe transmission and safety protection of the electric dispatching data network.
