Abstract: The frequent operation of the high-power pulse load equipment will affect the voltage and frequency of the power grid for the ships equipped with the high-power pulse load equipment. Based on the power station configuration of the power system of the full-scale ship, it analyzes the power supply programme according to the operation conditions of the high-power pulse load equipment, and proposes the corresponding load characteristic programme for the high-power pulse load. It also summarizes the relevant technical data of the generator sets, high-power pulse load equipment and electric propulsion equipment. The theoretical analysis and simulation of the key indicators, such as voltage, frequency and harmonic content of the power grid with the application of high-power pulse load, are carried out according to the actual operation conditions. Corresponding solutions are then proposed to ensure the normal operation of all the electrical equipment in the power grid.
