SYSTEM FOR CONTROLLING AND PROVIDING POWER TO AT LEAST ONE ELECTRIC MOTOR IN A VESSEL

摘要

A system for controlling and providing power to at least one electric motor in a vessel, such as a motor in a thruster or a winch. The system includes an electric energy storage, a power controller device connected to the electric energy storage, at least one motor controller device, a first combined power and communication line interconnecting the power controller device and the at least one motor controller device, an electric motor connected to the motor controller device, and at least one operating device connected to the power controller device. The system may further include a second combined power and communication line that interconnects the power controller device and the at least one operating device. The first combined power and communication line operates with a DC voltage level which is at least twice the operational DC voltage level of the second power and communication line.
