The power system of an all-electric navy ship has an integrated network, where the propulsion load, the distribution loads, sensor and other emergency loads and pulse loads (rail guns, aircraft launchers etc.) – all are part of the same electrical network. Among the loads, the effects of pulsed loads are most detrimental for the power quality of ship power distribution system as the pulsed loads require a very high amount of power for a very short period of time . In order to improve the survivability of a navy ship in battle condition, DSTATCOM or Distribution Static Compensator can be used, which reduces the impact of pulsed loads on the bus voltage and thus keeps the bus voltage at desired level.
