DC distribution system allows for new ways of thinking regarding operational optimization. The system is flexible and can combine different energy sources such as engines, turbines, and fuel cells. This means that there is the potential to implement an energy management system that takes into account varying fuel prices and the availability of ...
Long distance HVDC lines carrying hydroelectricity from Canada's Nelson River to this converter station where it is converted to AC for use in southern Manitoba's grid. A high-voltage direct current (HVDC) electric power transmission system uses direct current (DC) for electric power transmission, in contrast with the more common alternating current (AC) transmission systems.

A diesel-electric system is an integrated electric propulsion system in which no gas turbines are used and all of the engines are diesel. A turbine-electric system is also possible using gas turbine generators. Some yachts use only gas turbines for integrated electric propulsion without any diesel engines. If electric propulsion is used via ...
The ship is powered by a diesel electric DC/DC system composed of four Alco 251B diesel engines for propulsion and two Caterpillar 398 generators for AC electrical distribution. The propulsion system, rated at 6,469 kilowatts (8,675 hp), drives two fixed pitch propellers and bow thrusters, giving the ship a maximum speed of 17 knots (31 km/h ...

The ship successfully carried a crew of ten plus passengers at speeds of up to 15 km/h (8.1 kn) in Kobe Harbour in June 1992. [2] [20] Small-scale ship models were later built and studied extensively in the laboratory, leading to successful comparisons between the measurements and the theoretical prediction of ship terminal speeds.

Order processing operations or facilities are commonly called “distribution centers” or “DC 's”. There are wide variances in the level of automation associating to the “pick-pack-and-ship” process, ranging from completely manual and paper-driven to highly automated and completely mechanized; computer systems overseeing this process ...
