臺灣博碩士論文加值系統

船舶電力系統為一小型獨立系統，有限的備載容量與頻繁且大型的負載變動，容易造成系統不穩定。當系統大型負載啟動或閉合，船電系統之電壓、電流、頻率等容易發生變動，輕則影響船上照明設備，嚴重時可能造成船上精密設備損壞或系統全停電。為研究船舶電力系統在不同用電狀況下之動態響應情形，本文提出動態模擬分析技術來評估船舶在不同作業狀況下之電力系統動態響應。船舶電力系統主要設備，包括柴油引擎發電機、船艏側推進器、變壓器、冷凍貨櫃壓縮機等之動態行為被加以模式化，並使用Matlab/Simulink建構其模擬模組。測試結果以實際的船舶電力系統為例進行說明，幾種可能會影響船舶電力系統動態響應之狀況被加以模擬分析。本文所建立之船舶電力系統動態響應分析模式可提供有用的資訊給船舶設計人員在設計船舶電力系統及未來”全電力”推進船之參考。

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.
