The traditional means of power telecontrol communication must be changed because of the use of IEC 61850 standards in Substation communication. Considering the integration of IEC 61850 standards and IEC 61970, this paper presents an IEC 61850/OPC-based telecontrol communication model. The telecontrol information can be exchanged through ACSI/MMS services between IEDs in substation and OPC server in control center. The OPC server performs the mapping of IEC 61850 information models and OPC information model, and publishes information to SCADA applications which run as OPC clients. A prototype system is built to verify the feasibility of the model. It is proved that this system can meet the real-time requirements. It is different from gateway and need no complex protocol conversion.
