DC distribution system (ship propulsion) (original) (raw)

The DC distribution system has been proposed, as a replacement for the present AC power distribution system for ships with electric propulsion. This concept represents a new way of distributing energy for low-voltage installations on ships. It can be used for any electrical ship application up to 20 megawatts and operates at a nominal voltage of 1000 V DC. The DC distribution system is simply an extension of the multiple DC links that already exist in all propulsion and thruster drives, which usually account for more than 80 percent of the electrical power consumption on electric propulsion vessels.
