Pulse-load effects on ship power system stability

In this investigation, the performance of a fully-integrated ship power system with a pulsed power load is analyzed. There are particular loads in shipboard power systems such as electromagnetic guns, electromagnetic launch systems, and free electron lasers, which draw very high short time current in an intermittent fashion. In this research, the power system is thoroughly simulated to capture its transient and dynamic behaviors during the occurrence of a pulse-load. This simulation provides better understanding of the system performance and its stability under such severe conditions, and the results demonstrate the effect of different pulse-load characteristics, i.e. the magnitude and duration of the load, and the system topology, controllers and major parameters affect the stability of the system.
