Modeling and Simulation of Anti-Epidemic Auxiliary Marine Electric Power System

To ensure the safe and reliable ship operation under the epidemic situation, it is necessary to improve the anti-epidemic auxiliary capability of the ship electric power system. By analyzing the demand of Marine anti-epidemic auxiliary electric power distribution, the design key points of anti-epidemic auxiliary ship electric power system are obtained from three parts: source, network and load. Based on MATLAB/SIMULINK, a modular simulation model of anti-epidemic auxiliary ship power system, which containing high power medical equipment and frequency conversion equipment, is established and simulated under multiple working conditions. The simulation results show that the anti-epidemic auxiliary equipment will cause harmonic interference to the ship power system. After increasing the anti-epidemic auxiliary capacity, necessary harmonic suppression method is provided to keep the ship electric power system harmonic content in line with the standard requirements.
