Research on the Key Technology of Seamless Communication Between Smart Substation and Control Center

With the smart grid construction proceeding further, requirements increase on model and information sharing between control center and substation, and the current commonly used communication protocol between control center and substation has been unable to meet the demand of communication. This paper proposes a real-time service communication protocol, which is based on IEC61850, directly mapped the abstract communication service interface (ACSI) to the TCP/IP communication protocol stack, to build up a communication protocol in smart grid construction needs, meet the intelligent seamless communication requirements between control center and substation. Also the conversion model method and calibration method is also proposed.
