The invention discloses a three-remote signal acceptance system of an intelligent transformer station. The system comprises a waiting-for-acceptance signal storage module, a data flow module and a final signal storage module, wherein the data flow module comprises a rule storage module, a title verification module, an intelligent prompting module, an association configuration verification module and an electronized acceptance module, the waiting-for-acceptance signal storage module receives and stores waiting-for-acceptance three-remote signal data of an electrical network and sends the received data to the data flow module for flow processing, the data flow module sends the data after flow processing to the final signal storage module for storage, for the data flow module, the rule storage module stores title verification rules, association configuration verification rules and electronized acceptance rules, and the title verification module, the intelligent prompting module and the association configuration verification module sequentially carry out flow processing on the waiting-for-acceptance three-remote signal data. Through the system, hidden trouble to monitoring information correctness caused by disperse management on monitoring point information data are reduced, intelligent error detection and monitoring point error information correction are realized, and maintenance efficiency and information correctness of the automation system are improved.
