本論文於單部同步發電機經並聯輸電線併聯電網做為研究系統，並採用旋轉功率潮流控器做為控制系統，分別完成該系統在穩態、動態與暫態之穩定度分析。本論文於三相平衡系統下利用三相電路模型，分別建立三相三線式同步發電機、三相旋轉相位移變壓器、直流馬達、等效質量-彈簧-阻尼器模型與旋轉功率潮流控制器之控制系統等模型。本論文於穩態特性方面，分析包含於旋轉功率潮流控制器的兩部旋轉相位移變壓器位於各角度組合時，對系統功率潮流之影響與系統特徵值之變化。在動態與暫態模擬方面，分別完成了同步發電機之轉矩干擾與電網端發生三相短路故障等模擬結果，並比較原系統、含與不含控制系統之旋轉功率潮流控制器之間的差異。

This thesis employs a rotary power-flow controller (RPFC) as the control system to perform stability analysis of a one-machine infinite-bus (OMIB) system under steady-state, dynamic, and transient conditions. The three-phase circuit model is developed to establish the models for the three-phase three-wire synchronous generator, the three-phase rotary phase shifting transformer (RPST), the direct-current motor, the equivalent mass-spring-damper system model and the control system of the RPFC under three-phase balanced conditions. In this thesis, the steady-state characteristics of power flow and eigenvalues of the studied system under different angle pairs of the two RPSTs contained in RPFC are analyzed. Dynamic and transient simulations of the studied system subject to a torque disturbance and a three-phase fault at the power grid are also carried out, respectively. The responses of the studied system containing the RPFC with and without the control system are also compared.
