Abstract
Abstract β When a fault occurs in power systems, protective devices detect fault areas and disconnect the faulted sections of the network by opening circuit breakers, fuses etc.. Some loads become unavailable after the fault and should be reenergized, as quickly as possible, after the fault has been isolated. The re-energizing procedure is called service restoration. In Navy shipboard power systems (SPS), the automated reconfiguration for service restoration is a new focus area of research. The main objective of restoration on the SPS is to restore as much out-of-service load as possible by reconfiguration with priority given to critical loads. Once the switching actions to restore a load have been determined, the next step is to make sure that there are no operating constraint violations because of those switching actions. To check for constraint violations, line flows and voltage at each node need to be determined via a Load Flow. In this paper a method using ATP simulation, during runtime, to determine if the suggested switching actions for restoring loads violate any operating constraints, have been presented
