Voltage Stability in an Electric Propulsion System for Ships
This Master of Science thesis was written based on the shipbuilder Kockums AB feasibility study regarding the development of an AllElectric Ship for the Swedish Navy. The thesis was aiming at addressing voltage stability issues in a dc system fed by PWM rectifiers operating in parallel when supplying constant power loads. A basic computer model was developed for investigating the influence from...
متن کاملOptimization-based control of diesel-electric ships in dynamic positioning
Recent advances in computer hardware and algorithms make it possible to consider more computationally demanding control methods, allowing more effective exploitation of the equipment under control. This thesis explores new ways of controlling ships (or other marine vessels) that are designed to keep a predetermined position and heading automatically exclusively by the means of their thrusters –...
متن کاملOptimal Power Management for Failure Mode of AC/DC Microgrids in All-Electric Ships
Optimal power management of shipboard power system for failure mode (OPMSF) is a significant and challenging problem considering the safety of system and person. Many existing works focused on the transient-time recovery without consideration of the operating cost and the voyage plan. In this paper, we formulate the OPMSF problem considering the longtime scheduling and the faults at bus and gen...
متن کاملHybrid Optimization Method for Reconfiguration of AC/DC Microgrids in All-Electric Ships
Since the limited power capacity, finite inertia, and dynamic loads make the shipboard power system (SPS) vulnerable, the automatic reconfiguration for failure recovery in SPS is an extremely significant but still challenging problem. It is not only required to operate accurately and optimally, but also to satisfy operating constraints. In this paper, we consider the reconfiguration optimizatio...
متن کاملConstructing rules for dismantling ships.
Labor groups, environmental activists, and shipping experts have begun finalizing international guidelines that would reduce threats from toxic substances released during the ship scrapping process and would protect the health and safety of laborers who dismantle ships. In June 2001, government representatives and stakeholders in the ship dismantling industry gathered in Geneva, Switzerland, to...
