同步發電機參數於電力系統穩定度之影響

本論文主要探討同步發電機的電力系統，在改變參數後對電力系統穩定度的影響。該系統主要包括同步發電機、5MW 負載、三相變壓器、10MW 負載、三相接地故障以及電網。研究方法是使用MATLAB 內建模組，調整激磁系統及調速器的參數，最後進行模擬，從臨界清除時間來看暫態穩定度的影響，從波形週期來看穩態穩定度的影響。研究結果顯示，此系統在這種參數調整情況下系統穩定度都是可以接受的。本研究最大的價值是調整參數對系統的穩定度影響大小的重要參考資料。

In this thesis, the influence of parameters change in the synchronous generator power system to the power system stability is discussed. The system includes synchronous generator, 5MW load, three-phase transformer, 10MW load, three-phase ground fault and the grid. The system is simulated with MATLAB internal module by adjusting the parameters of exciting system and the speed governor; the transient stability performance is judged by critical clearing time, and the steady state stability is judged by observing the time domain waveform. The result shows that the system stability is acceptable while adjusting the parameters in this sort of system. The value of this thesis is to establish critical reference data of system stability while adjusting parameters in the system mentioned above.
