Supervisory Control and Data Acquisition (SCADA) applications in power system control centres usually communicate with other subsystems by using some common telecontrol protocol such as IEC 60870-5-101, IEC 60870-5- 104 or DNP3. One of the major drawbacks of this approach is the lack of standardized process data semantics. This feature significantly decreases capability of streamlined configuration and maintenance of control centre SCADA systems. Majority of newly integrated substations are based on IEC 61850 standard which provides integrated process data semantics. According to common practice, substation-level process data based on IEC 61850 are mapped to some of aforementioned telecontrol protocols. This process results in several negative impacts such as inevitable loss of data semantics, introducing additional latencies in data-exchange processes and error- prone configuration. These and similar issues could be eliminated by using IEC 61850 communication at control centre level. This paper provides an outline of current standardization results related to IEC’s Technical Committee 57 (TC57) efforts which aim to develop IEC 61850-based communication towards control centres. It is also shown how these features are applied in industrial practice as a functional part of PROZA NET SCADA system. |
