Arrangement of Data Exchange between Adaptive Digital Current and Voltage Transformer and SCADA-system under IEC 61850 Standard

The paper presents the approach for solving the task of development of technology of high accuracy measurement digital information transmission via communication system from remote terminal unit on the base of adaptive digital combined current and voltage transformer (ADCCVT) to SCADA-system. We showed the design and technical characteristics of the said transformer, ADCCVT–SCADA communication system structure and also the programming model of data exchange between ADCCVT and SCADA-system. We analysed transformer design features determining the technology and means of data transmission. Discussed an opportunity of using the universal SCADA-systems and OPC-servers for control digital substations under IEC 61850 standard. Presented the modelling results.
