The function and the demand of the smart substation's automation system network are researched in this paper. The point-to-point networks for the direct sampling and trip of the protection and some typical network scheme are discussed with the reference of <;The design regulation of the smart substation>; and <;The protection technical regulation of the smart substation>;. The configuration of the net switcher and the link of the optical cable are studied in this paper. The principle and basis of the network configuration of the smart substation are proposed.
