Electrical Distribution Systems (EDS) are facing ever-increasing complexity due to fast growing demand and large amount of distributed energy resources integration. The conventional operation modes need to adapt the significant changes. The behavior of EDS needs monitoring and executing in a high speed and a reliable manner. With advanced Information and Communication Technology (ICT) infrastructure using more and more Intelligent Electronic Devices (IEDs) and sophisticated new functionalities for energy management, "Smart Grid" is becoming the most forward-looking solution to address these facing challenges. Having initiated a conceptual model, architecture, and implementation plan for the system in previous European research projects [1],[2], an integrated ICT - platform based distributed control and local management solution to demonstrate the feasibility of the new concept is under design. In this framework of the project, the author realized the real-time communication between a fault passage indicator Flair200C (Schneider Electric) and a MATLAB based local agent by using MATLAB OPC toolbox. The real-time communication will be used to realize an advanced fault location functionality which is developing in order to improve the reliability and quality of electrical distribution system.
