Research on simulation of shipboard MVDC integrated power system based on PLECS

Aiming at shipboard medium voltage DCMVDC integrated power system, the structure and characteristic of the system is analyzed in this paper. The mathematical model of the system, including prime-mover, generator, propulsion motor and four-quadrant propeller load is proposed. Then the simulation model of MVDC shipboard integrated power system is established in PLECS simulation software, and the numeric simulation of the normal and emergency operating conditions such as start, speed up and crash back is carried out. The simulation of the normal and emergency conditions for the whole system is then achieved. The simulation results validate the research of the numerical simulation for the shipboard MVDC integrated power system, which can provide simulation tools in the early design stage for the system.
