本論文係針對三相感應發電機與市電系統並聯運轉時，分析在系統上可能發生之動態與穩態的特性。文中分別以單台風力感應機連接市電以及四部風力感應機與市電系統連接，探討其之間相互影響。在系統穩態分析方面，本論文分別針對感應發電機的轉子電阻、電容值、市電端電壓、傳輸線(含地下電纜)、發電機內部參數等對系統特性之影響，做一併討論。在動態研究方面，本論文則針對感應發電機瞬間和市電解聯及投入市電時，對系統及感應機發電機造成的影響做評估分析。在暫態研究方面，本論文分析故障發生時對系統產生衝擊及影響。本論文另將靜態無效功率補償器連接至感應機發電機端來控制其端電壓，使其穩定在一定範圍。由本論文的動態及穩態模擬結果，可以針對與市電並聯運轉之多部風力用感應發電系統提供完整的特性研究分析。

　This thesis analyzes both dynamic and steady-state performance of wind turbine-induction generators connected to a utility grid. The studied system contains a single wind induction generator and four serial-operated wind induction generators connected to a utility grid. The steady-state results of the studied system under different values of rotor resistance, excitation capacitor, line impedance, and machine parameters are explored. Dynamic characteristics of the studied wind induction generators subject to sudden connection to and disconnection from the utility grid are studied. Transient responses of the studied wind induction generator under faulted condition are also examined. This thesis also proposes a set of static VAR compensator (SVC) connected to the output terminals of the studied wind induction generator to regulate bus voltage within an acceptable range. From the simulated results, the performance of the studied grid-connected wind turbine-induction generator system can be obtained.
