本論文係以聚集等效風場經由傳輸線並聯市電架構
下，比較含與不含飛輪儲能系統之穩定度、穩態及動態做為
研究目標。在三相平衡系統下採用交直軸等效電路模型，分
別建立風、風渦輪機、感應發電機以及飛輪儲能系統等之模
型，並推導其數學模型來完成整體動態方程式。在穩態方
面，則分別對不同風速及變動飛輪儲能系統之控制參數等量
對系統特性之影響做一詳細討論。在動態研究方面，完成轉
矩干擾、市電端電壓下降及變動風速等模擬。由模擬結果顯
示，飛輪儲能系統確實能夠有效改善風場在變動風速及干擾
下之動態特性。

This thesis presents the analyzed results of stability, steady state, and
dynamics of an equivalent aggregated wind farm (WF) connected to a
utility grid through a transmission line with and without a flywheel
energy-storage system (FESS). The d-q axis equivalent-circuit model is
employed to establish the models for wind, wind turbine, induction
generator, and the FESS to derive the complete dynamic equations of the
studied system under three-phase balanced loading conditions.
Steady-state performance of the studied system under different wind
speeds and various control parameters of the FESS are examined.
Dynamic simulations of the studied system subject to torque disturbance,
voltage drop of utility grid, and variable wind speeds are also
implemented. It can be concluded from the simulation results that the
proposed FESS can effectively improve the performance of the studied
WF under disturbance conditions and variable wind speeds.
