摘要

本論文針對分散式電源進行低電壓穿越能力控制之研究，文中以風力發電系統為例，利用柴油發電機及儲能來改善風力發電系統於故障時之低電壓穿越能力。為證明本文提出的研究方法，首先整理出風機系統不同的運轉風速及負載情境；其次，建置柴油發電機及儲能進入系統中；最後，透過Matlab/Simulink模擬軟體進行故障模擬，以觀察風機系統故障電壓及電壓恢復時間，並進行結果比較及分析。經模擬結果顯示，對於儲能加入風機系統運轉，於系統發生故障時，因儲能系統具有快速實虛功率補償能力，可使其風機系統電壓恢復時間縮短，進而在系統穩定度等方面較具優勢。

This thesis studies the control of low-voltage ride-through capability for distributed wind power generation system. The diesel generator and energy storage are used to improve low voltage ride-through capability of wind power generation system during system fault contingency. First, the various wind turbine system operating wind speeds and different load scenarios are studied; the second is to build diesel generator and energy storage models into the wind power system; finally, the responses of wind turbine system voltage and voltage recovery time during system fault period of time are simulation by Matlab/Simulink software. The simulation results show that the shorter voltage recovery time can be obtained by fast real and reactive power compensation of energy storage to improve wind power system stability.
