碩士 / 國立高雄海洋科技大學 / 輪機工程研究所 / 106 / With the rise of awareness of environmental protection and energy saving, it is necessary to import the electrical power system to achieve the effect of effective energy saving. In addition to the emphasis on the industry on land such as hybrid cars, electric bus, etc., the ship electrical power system is equivalent to a special island grid system. The load fluctuation under the limitative reserve capacity may easily cause the instability to the ship electrical power system. In order to enhance the competitiveness of maritime industry, many ships have gradually imported more electrical equipment and electrical power compound systems, so the increase in short circuit fault current is necessary. The voltage, current and frequency of ship electrical power system change easily, which will affect the relevant lighting equipment on the ship in the minor cases and may cause the damage to the precision equipment on the ship or power failure to the system in severe cases.
With the use of software application of Simulink, this research established the module to compare the electrical power system of one hybrid power ship of ferry companies in Kaohsiung City. The calculation of short circuit fault current via the software can provide the more accurate numerical parameter module and offer protection reference after the completion of the early DC system design and basic design of relevant projects. This research is mainly aimed to discuss the numerical parameters of DC short circuit fault current through the analog computation results to analyze the safety assessment of this protective equipment on DC electrical power system.
