Simulation Board for Smart Service Restoration Schemes in Distribution Grid

The paper presents a new fault location isolation and service restoration (FLISR) scheme, as well as a design and construction of a simulation board where the FLISR scheme is implemented and tested using a DC scaled power distribution system. Testing with different fault locations and load levels shows that the FLISR scheme works effectively. The system can automatically detect faults on distribution feeders, isolate them, and distribute affected loads to neighboring circuits. The simulation may be used to test diverse FLISR schemes. In addition, the scaled model may allow for replication in larger models to be implemented into real-world power distribution systems. Furthermore, the simulation board is useful as an interactive training and public education tool for FLISR schemes, as well as for smart grid concepts of sensor, microcontroller-based control, and automation.
