The invention discloses an intelligent substation communication method and system based on an information center network. The method includes the steps that firstly, a client side A sends a data access message to an uplink router A, a message header comprises a data access request and a unique route distinguisher, and the unique route distinguisher is the information name comprising authorization attributes; secondly, the uplink router A forwards the data access message to a transformer substation data source end, the data source end returns a result message to a router in a transformer substation data transmission network, and a message header of the result message includes the responsive data access request, result data and the unique route distinguisher, wherein the result data and the unique route distinguisher are provided for the client side A; thirdly, the authorization attributes of the unique route distinguisher are detected, if the authorization attributes are authorization or delegation authorization, the router has the cache function, and the router is then used for storing the result data and forwards the result data to the client side A. According to the intelligent substation communication method and system based on the information center network, redundant data can be reduced, and the network resource utilization rate and the power data transmission efficiency are improved.
