Department Electrical Engineering Year 2006 Semester 1 Degree Master Type of Document Master's Thesis Language zh-TW.Big5 Chinese Page Count 80 Title The Characteristics Analysis of Electric Machinery Driving Speed-adjustable Ship in MW Grade Keyword propulsion motor motor driver The electric speed adjustable cruiser propulsion The electric speed adjustable cruiser propulsion motor driver propulsion motor Abstract 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.
