Power management system of medium-voltage electric propulsion ship

The utility model relates to a power management system of a medium-voltage electric propulsion ship. Electric quantity transmitting devices send field signals to generator set controllers; the generator set controllers analyze data and output control signals to parallel operation devices and relay units in on-site control boxes; and a PMS controller receives field signals by the electric quantity transmitting devices, receives an instruction of a human-computer interface and data of the generator set controllers by an Ethernet switch, and sends out control instructions to the generator set controllers. According to the utility model, power management of a medium-voltage electric propulsion ship power station can be realized. The modular design is utilized; software and hardware interfaces are arranged; the system is packaged independently; and the control parameters can be adjusted. An appropriate interface can be selected according to the type of a ship power device, thereby realizing load management of diff
