碩士 === 國立高雄海洋科技大學 === 輪機工程研究所 === 95 === A shipboard electric power system is a small and isolated system. The limited spinning reserve and frequent and large electric load variations have degraded the system stability. When large electric loads start and stop, the voltages, currents, and frequency are often varied, which significantly affects the operations of lighting devices and precise instruments and may lead the electric power system to collapse. To investigate the dynamic response of shipboard electric power systems, a dynamic simulation technique is proposed in this thesis to analyze their dynamic performances under different ship operation conditions. The dynamic behaviors of shipboard electric apparatuses including diesel generators, bow thruster, transformers, reefer containers are modeled mathematically and their simulation modules are built by using Matlab/Simulink software. Test results of a simulated shipboard electric power system are presented. Several cases that significantly affect the dynamic response of the shipboard electric power system are simulated and analyzed. The analytical models presented in this thesis could provide useful information to shipboard designers in devising the shipboard electric power systems and all-electric ships.
