$~~~~~~~$本論文旨在透過即時模擬之軟體迴路分析配電型靜態同步補償器(D-STATCOM)。使用Dommel法配合梯形積分法建構出電壓源換流器(VSC)之即時模型，經鎖相迴路控制(PLL)使系統相角與電壓源端相角達到鎖相控制，而其控制器包含交流電流控制、直流電壓控制、交流電壓調變控制及功因校正。\\\\
$~~~~~~~$實現方法以Labview為平台達成軟體迴路之即時模擬系統，並採用極小時間步階法實現即時模擬，模擬將分為穩態與暫態。模擬結果與PSCAD/EMTDC離線模擬系統進行驗證比較與討論。

$~~~~~~~~~$Simulation plays a vital role in power system as it helps engineers to analyze a large and/or complicated system before the system is actually being implemented. Simulation can greatly save money and help to prevent things such as catastrophic failure from happening. Simulation can be classified into offline simulation and real time simulation. A real time simulator, operated at real time, can be interfaced with an actual hardware to help the engineer to investigate and study a close-to- real-world system.\\
$~~~~~~~~~$A real time simulator can be classified into three types hardware-in-the-loop, rapid control prototyping and software-in-the-loop. A hardware-in-the-loop system consists of a simulated plant interacting with an actual controller. A rapid control prototyping system consists of an actual plant interacting with a simulated controller. Software-in-the-loop system is made of a simulated plant interacting with a simulated controller. This thesis will show how a software-in-the-loop simulation of a D-STATCOM can be implemented in the LABVIEW environment. To account for the problem of external events occurring between the simulation time grids, we employed the method of very small time step. To avoid the problem of inverting a matrix in real time, we proposed to update the dc voltage in every other step. The software-in-the-loop results are compared with those obtained from the offline simulation via PSCAD/EMTDC to show the validity of the proposed method.
