Self-healing grid is a system equipped with superior software program, computerised control, smart sensors that utilize real time distribution facts to detect and cut off faults. It has ability to reconfigure distribution network and reduce the number of customers affected. Distribution structures are becoming more and more complex with addition of electric vehicles, IoT devices and distributed energy source along with renewable sources. To improve the system reliability it may require reconfiguring switches and circuit reclosers installed on distribution feeder. It helps to isolate faults in affected section and restore service to as many customers as possible from alternate sources. This technology connects smart reclosers and circuit breakers from alternative feeders and enables them to operate in organized manner. Self-healing grid can provide sophisticated protection to the assets and electric utilities.
