摘要

本論文之目的在實現電力電子即時數位模擬器(Real Time Digital Simulator, RTDS)。即時數位模擬器可實現硬體迴路試驗，因此可完成一般數值模擬軟體所無法達到之功能。本文在即時數位模擬器部分討論系統狀態方程式模型、數值計算方法、開關訊號擷取方式和人機介面。為了與即時數位模擬器比較，本文採用開關函數以加快軟體模擬速度。
本文即時數位模擬器採用數位訊號處理器(Digital Signal Process, DSP) TMS320C6416取代電力電子電路，並結合Altera DE2-70 FPGA開發板作開關訊號整合，之後再經由ORS-114擴充卡作類比輸出；而在控制器部分則採用TMS320F2808作為控制平台。為驗證即時數位模擬器可行性，本文分別以降壓型轉換器和半橋式變流器作為模擬案例。即時數位模擬器實測結果除了能夠即時輸出，並且和MATLAB/SIMULINK及IsSpice軟體模擬結果相仿，因此可驗證即時數位模擬器之正確性。

The main purpose of this thesis is to realize Real Time Digital Simulators (RTDS). RTDS could achieve Hardware-In-the-Loop (HIL) tests which cannot be done by software simulations. This thesis discusses state-equation models, numerical methods, switching signal acquisitions and a Human-Computer Interaction (HCI). To compare with RTDS, a new switching function to reduce simulation time in numerical simulations.
The digital signal processor, TMS320C6416, is used to replace power electronic circuits and combine with Altera DE2-70 for integrating switching signals. Then, ORS-114 peripheral card is used to output analog signal. Besides, the digital signal processor, TMS320F2808, is used as a control platform. Finally, a half-bridge inverter and a buck converter are selected to realize the proposed RTDS. Experimental results show that RTDS could realize effectively work in real-time, These results are compared with MATLAB/SIMULINK software to confirm the accuracy of the proposed RTDS.
