碩士 / 國立臺灣海洋大學 / 電機工程學系 / 98 / The shipboard electric power system is an independently operated system. The external help will not be immediately available if machine failure or contingency occurs when the ship sails on the sea. Moreover, the required reliability of the shipboard electric power system is higher than that of the seashore power system since the frequent load variations on board are likely to result in system instability.
In order to study the dynamics of the shipboard electric power system in various loading states, we adopt a sample s study system of which the equivalent dynamic models under four operating conditions are established. Then based on time-domain performance indices, such as maximum overshoot, settling time, and damping ratio, the system dynamic responses subject to small disturbance under different values of excitation system parameter are investigated for finding the proper parameter of the excitation system. To verify the effectiveness of parameter tuning of the excitation system in improving the system dynamic characteristics, the time-domain approach is also employed to compare the system responses subject to large disturbance before and after the adjustment of excitation system parameter. It is found that proper setting of excitation system parameter is capable of improving the system dynamic characteristics.
