本論文係分析單部市電併聯型風力感應發電機於超過額定風速下利用極點安置法理論來設計葉片旋角控制器，其中包含時域與頻域的分析，並針對不同程度擾動風之擾動量去探討葉片旋角控制器之強健性。在本論文中，除了建立風的模型外，在三相平衡系統下採用交直軸等效電路來建立風渦輪機、感應發電機與傳輸線等之模型，並推導其狀態方程式以分析系統穩定度。在穩態方面，則針對葉片旋角角度、風剪效應、風向、風力塔高度、葉片長度、空氣密度等對系統之影響，分別做詳細討論。在動態方面，則考慮發生干擾或故障時，分析可能對風力發電系統造成之影響。最後利用靈敏度方法與參與因子法來分析參數變動對系統之影響及狀態變數與特徵值之間的關係。

This thesis analyzes performance of a grid-connected wind induction generator with pitch controller design using pole-assignment technique. Both time-domain and frequency-domain approaches are employed to systematically examine the robustness of the proposed pitch controller under various wind speeds. The models for wind turbine, induction generator, and transmission line are combined to establish the complete state-space equations of the studied system under three phase balance loading conditions. Blade’s pitch angle, wind shear, wind direction, height of wind tower, length of blade, air density on steady-state characteristics of the studied system are also examined. Dynamic characteristics of the studied wind induction generator subject to disturbance and faulted conditions are explored. Finally, sensitivities and participation factors are both utilized to investigate the relations among system parameters, eigenvalues, and state variables of the studied system.
