摘要

本論文提出變轉速船舶全電力推進系統，此系統主要由同步發電機、
隔離變壓器、三相橋式整流、變頻器、感應電動機及螺旋槳所組成，
以柴油引擎驅動同步發電機產生電力，再驅動可變速推進電動機及螺槳。
此架構中，以兩組推進電動機驅動螺槳使得船體前進、後退及轉彎，
本論文針對可變速推進電動機做動態的特性分析，包括全壓起動、
軟起動、加速、減速、煞車及緊急逆轉，
以Matlab/Simulink模擬此電機與機械在各種狀態下操作對推進系統動態響應，並評估
推進系統的穩定度及設置保護設備，避免推進系統的不穩定影響電力設備的安全性，
模擬結果及分析可做為日後設計船舶全電力推進系統之主要依據。

The electric speed adjustable cruiser propulsion system is presented in this thesis.
This system consists of synchronous generator, isolation transformer,
three-phase rectifier, motor driver, propulsion motor, and propellers.
In the proposed scheme, the diesel engine drives
generator to produce electric power for two sets of motor which drives propeller to
propel the ship moving forward, backward and turned around.
The dynamic characteristics analysis of the electric motor includes soft
start, forward, reverse, stop and urgent reverse in this thesis.
The dynamic response of
the speed-adjustable propulsion under various dynamic operating conditions
are simulated by using Matlab/Simulink. Furthermore,
in shipboard system the stability and equipments of protection are estimated
avoiding unstable system affected safety of power equipments. Therefore electric motor
and propulsion driver could be chosen in accordance
with the analyzed characteristics and simulation results.
