本文旨在開發一由間接磁場導向感應馬達驅動之原動機模擬器。此感應馬達驅動系統可操控成速度模式之傳統原動機，或轉矩-速度模式之風渦輪機。在此兩模式下，變頻供電感應馬達驅動系統分別操作於速度控制模式以及直接轉矩控制模式。因此，為獲得較佳之間接磁場導向感應馬達驅動特性，本文提出改善之感應馬達參數估測技巧。實驗結果顯示，不同風速下之轉矩-速度曲線可被忠實呈現。
為從事所建原動機模擬器之加載測試，建立一具後接三相維也納升壓切換式整流器之內置磁石式永磁同步發電機。渦輪機接收機械能，並建立四百伏特之直流微電網共同匯流排。同時施行換相移位調適，以得內置磁石式永磁同步發電機之最佳產生功率。另外，亦採擾動觀察法從事風渦輪機模擬器驅動發電機之最大功率追蹤控制。而維也納切換式整流器之故障容錯操作，亦從事之。
為使所開發渦輪機模擬器可從電網供電且具良好之入電品質，構建一入電端之三相升壓型維也納切換式整流器。最後以一些實測結果，詳予評定所建切換式整流器供電風渦輪機模擬器之總體操控效能。
關鍵詞：原動機、風渦輪機、模擬器、感應馬達、磁場導向、內置磁石式永磁同步發電機、維也納切換式整流器、最大功率追蹤。

This thesis develops a prime mover emulator driven by an indirect field-oriented (IFO) induction motor (IM). The IM drive can be operated as a conventional prime mover in speed mode or a wind turbine in torque-speed mode. For these two modes, the inverter-fed IM drive is respectively operated under speed control mode and direct torque control (DTC) mode. To let the IFO IM drive possess satisfactory operating characteristics, the improved induction motor parameter estimation procedure is proposed. In the developed wind turbine emulator, experimental verification shows that different wind turbine torque-speed curves under various speeds can be faithfully emulated.
To conduct the loading test of the established prime mover emulator, an interior permanent-magnet synchronous generator (IPMSG) followed by a three-phase Vienna boost switch-mode rectifier (SMR) is constructed. It receives mechanical driven power from the turbine and establishes a 400V DC-link for DC micro-grid. The commutation tuning to optimize the IPMSG developed power is arranged. The maximum power point tracking (MPPT) of the wind turbine emulator driven IPMSG is achieved using the perturbation and observation (P&O) approach, and the fault-tolerant operation of the Vienna SMR are also conducted.
Besides, in order to let the developed turbine emulator be powered from the utility grid with good power quality, a source side three-phase Vienna boost SMR is also established. The whole SMR-fed wind turbine emulator driven IPMSG system is then completely evaluated.
Key words: Prime mover, wind turbine, emulator, induction motor, field-orientation, IPMSG, Vienna SMR, maximum power point tracking.
