A fast recovery method for ship power supply system power loss
In order to quickly and accurately locate the fault point and effectively restore power supply in the event of power failure in the ship power supply system,this study designs a fast recovery method for ship power supply system power loss based on network topology directed traversal technology.After the power outage fault indicator in the ship's power sup-ply system issues a power outage warning,a directed graph of the power supply system network topology is constructed,where each vertex and edge of the graph represents the line nodes.Using depth first search traversal algorithm,search for the warning range of fault indicators one by one,and locate the location of power loss faults;Based on the location of power loss faults,a fast recovery model for ship power supply system is initiated to construct a power loss recovery objective function that maximizes the speed of load recovery and minimizes the number of switch actions.The differential evolution algorithm is used to solve the standby generator set start stop and load switch switching schemes that meet the objective function condi-tions,achieving fast recovery from power loss.Experimental data shows that this method can quickly achieve power loss re-covery within the range of 1.05 seconds.
