Reconfiguration and restoration of distribution systems

For decades, distribution systems were designed with rigid topologies and limited possibilities for change in configuration. Improvements achieved by the manufacturers in recent years have prompted the use of feeder reconfiguration to modify the topology of distribution networks. These improvements include remotely controlled switches and breakers for pole installation, numerical protection, and appropriate communication systems Prior to determining the location of switches to allow changes in configuration, it is highly recommended to find the best topology for a distribution system. Under normal operating conditions, feeder reconfiguration aims for a more efficient operating condition of the network. Under faulty conditions, feeder reconfiguration aims to restore the service to the maximum number of users in the shortest time.
