本論文係利用聚集方法推導風場之等效風渦輪機模型，並在同步旋轉參考軸下建立等效感應發電機連接虛功補償元件之系統架構。文中的靜態同步補償器與靜態虛功補償器其目的在於改善該風場系統受到干擾下之動態特性並穩定該系統。靜態同步補償器模型中含有調變指數以及電壓相角等變數，其目的在於控制匯流排上電壓變動。在靜態同步補償器中的比例-積分-微分型控制器與輸出回授型控制器皆以極點安置法來設計，並利用頻域之特徵値分析法以及時域的動態模擬來驗證此控制器之效能。在動態分析方面，則考慮系統發生干擾或故障時，探討對於風場所造成之影響。
由本文之動態及穩態之模擬結果顯示，靜態同步補償器確實能夠有效改善風場在不同風速及干擾下之動態特性。

This thesis establishes an equivalent wind farm model using aggregated wind induction generators. The models of a reactive power compensators, static synchronous compensator (STATCOM) and static VAR compensator (SVC), connected to the wind farm is based on the synchronously rotating (d-q) reference frame model to improve system dynamics under disturbance conditions The STATCOM model with modulation index and voltage phase angle is effective to control the voltage profile of the studied wind farm. A proportional-integral-derivative (PID) type and an output feedback (OPFB) type controller of STATCOM are designed using a pole-assignment technique.
For demonstrating the performance of the proposed damping controllers, frequency-domain approach based on eigenvalue analysis under different operating conditions as well as time-domain scheme based on nonlinear model simulations under disturbance conditions are both performed. It can be concluded from the simulation results that the proposed STATCOM is capable of improving system performance of the studied wind farm under various operating conditions.
