An adaptive, agent-based protection scheme for radial distribution networks based on IEC 61850 and IEC 61499

This paper shows a possible implementation for an auto configurable protection scheme based on the well-known logic selectivity concept, using an agent-based architecture with standard communication protocol (IEC 61850) and programming language (IEC 61499). An easy-to-use technique to integrate the two standards is shown, enabling the exploitation of encapsulation capabilities provided by IEC 61499 to provide easy to maintain and reusable code, along with interoperability with 61850-enabled IEDs. The proposed scheme can also implement automatic reconfiguration of protections following network topology changes.
