Abstract：According to the new characteristics of DC zonal electric distribution in the vessel integrated power system (IPS) and aiming at the problem of overload of the inverter due to motor start-up, a primary load transfer model and a secondary load transfer model were respectively established with a safe motor start-up as the prerequisite and the minimum switching loss as the goal. Then, the amount of load in the DC zonal electric distribution system (DC-ZEDS) under different operating conditions was compared with the safe boundary given by the total supply capability (TSC) model for load transfer. On this basis, a heavy-load inquiry process was offered according to different load priorities. Finally, for the load distribution under different working conditions, corresponding preventive control strategies were proposed, which can deal with the inverter overload due to motor start-up and avoid load-shedding operation to the uttermost.
