Analysis of the methods of transmitting telecontrol information in substation through digital network

In accordance with the mode of telecontrol series-communication which is widely used in electric power automated system, combined with the practice of communication and MIS network in Baoji Power Supply Bureau, the feasibility, necessity and the benefits of the telecontrol information transmission were analyzed, the methods and some relevant technological schemes were researched, and some new technology which used in the transmission mode were introduced, such as Ethernet technology, TCP/IP protocol. At last, point out that the transmitting of the telecontrol data will adopt the network transmission mode.
