碩士 === 國立臺灣海洋大學 === 電機工程學系 === 104 === This thesis studies on dynamic analysis of Ocean Thermal Energy Conversion, including open-cycle and closed-cycle OTEC system which both have flow rate control model. The study analyzes dynamic characteristic and variation in seawater flow rate when system operate on islanding and grid-connect. From the study results, it is shown that closed-cycle OTEC can generate same power with less seawater flow rate than open-cycle OTEC. Seawater flow can’t change so rapidly that it results in a disturbance on the generator output. When micro-grid is connected to the electricity, voltage and frequency can be returned to normal steady state.
