本論文的主要目的在探討風力發電之暫態特性，研究內容包括風力發電系統併網前後之暫態特性模擬與故障電流變動分析，針對不同風機併網位置與數量進行模擬與探討。本論文主要以MATLAB/Simulink 模擬軟體建立分析所需之配電範例系統，再應用不同之控制策略探討風機對饋線電壓及故障電流等的影響。模擬過程中，風力發電機採用變動之風速，以資探討風力發電系統在正常運轉與系統故障各情況下的暫態特性，模擬結果可作為評估風力發電機併網可能對系統造成衝擊之參考。

The major purpose of this thesis is to analyze the transient phenomena of wind generation while interconnection with a distribution network. The major research focuses include the transient phenomena analysis and fault level evaluation, the impacts of interconnection locations and capacities of the wind generations on a distribution feeder were evaluated as well. Two wind generation models and a full-scale distribution network model were developed by using MATLAB/Simulink. Based on the developed models, different control strategies were applied to investigate the impacts of various types of wind generations on the voltage profiles and fault level variations along a distribution feeder. Time-varying wind power was applied for simulating the transient behavior of a wind farm under normal and abnormal operating situations. The simulation results show a considerable impact of the distributed wind generation on the distribution networks.
