當系統發生短路故障造成大型離岸的風場因系統低電壓而跳脫可能導致對系統的重大衝擊，本研究利用軟體建立離岸風場藉由不同傳輸方式的模擬模組並加以分析，離岸風場由定速型感應發電機所組成，三種與岸上電力系統連接方式分別為高壓交流傳輸，高壓交流傳輸加入靜態同步補償器，和以電壓源轉換器為基礎的高壓直流傳輸方式。本研究模擬與比較在岸上電力系統發生三相短路故障時對於三種傳輸架構之動態響應，並建立不同傳輸架構之電壓忍受曲線，且與各國電力公司所訂定的低電壓忍受能力標準比較。

Large off-shore wind farms raise the concern of widespread tripping of off-shore wind generator in the presence of system faults and corresponding voltage dips that could potentially cause system wide blackout. In this thesis an offshore wind farm and three different types of power transmission are modeled and studied using simulation software. Off-shore wind farm composed of fixed speed induction generators and HVAC interconnection, HVAC interconnection plus STATCOM and HVDC interconnections are studied. Onshore grid faults are simulated for each interconnection. Voltage tolerance curves are established to assess fault ride through capability of each interconnection and compared with different grid transmission ride through capacity required by grid operator.
