Programmable logic for IEC 61850 logical nodes by means of IEC 61499

IEC 61850 is a recent standard in substation automation system (SAS) aiming mainly at interoperability. Interoperability is achieved by standardizing communications and data between intelligent electronic devices (IEDs). Data in intelligent electronic devices are modelled in IEC 61850 using an object orientated approach as logical nodes. Although the IEC 61850 standardizes the data and communication in substation design, the implementation of control is intentionally left out of the standard. IEC 61499 function blocks has been proposed to fill the logic void of the IEC 61850 standard. In this paper, intelligent logical node (iLN) architecture is used, which combines both description and control within IEC 61850 logical nodes. An IEC 61850 application presented at the IEC TC57WG10 has been modelled using the iLN architecture with the addition of editable logics within the iLN architecture by means of IEC 61499 function blocks implemented in the ISaGRAF development platform.
