Technologies of the self healing grid

A self-healing grid refers to automated ways of removing temporary faults from the distribution power network. This paper will present three available technologies to help utilities improve overall system reliability by restoring power to the healthy portions of the grid. Three technologies were selected to support utilities´ achievement of service quality goals at different budgets and to start implementation of Smart Grid oriented FDIR - Fault Detection Isolation and Restoration- schemes. This will mitigate losses of revenues, penalties from regulators and cost of restoration while improving customer satisfaction.
