| Abstract:Aiming at the problems of over-current and maloperation of relay protection in the process of seamless operation of ship shore power, a fault diagnosis method based on the improved binary wind driving algorithm for ship shore is proposed. The relay protection scheme of ship shore power system is analyzed, the state relation among various relay protection under the condition of refuse operation/unwanted operation in relays and circuit breakers and its comprehensive influence on shore power system for ships are studied. The suitable mathematical model of fault diagnosis about shore power system for ships is selected and then solved by improved binary wind driven algorithm. Finally, the model is verified by two fault examples, and the rationality of the fault model and the reliability of the algorithm are fully proved.
