Gateway for linking smart power distribution system and ami system, and system linking method using same

The present invention provides a gateway for linking a smart power distribution system and an AMI system, and a system linking method using same. A gateway for linking power distribution-AMI comprises: a data model for configuration functions of a plurality of AMI systems and an AMI link processing unit that is connected to the plurality of AMI systems and transmits/receives data using a plurality of first protocols; a functional data model including a data model for a meter measuring function and a data model for a road profile function; and a power distribution link processing unit for converting data delivered using the first protocol at the AMI link processing unit so as to enable transmission/reception in the smart power distribution system using a second protocol by using a functional data model, and for converting data delivered using the second protocol different from the first protocol in the smart power distribution system so as to enable transmission/reception in the AMI system, which uses the first protocol, by using the functional data model.
