隨著國內高科技產業發展越來越迅速，科學園區中各領域應用之數位儀器及高敏感性之設備比重日益增加，所使用之敏感性設備越多，其對供電品質的要求也就越高，因任何有品質問題的電力供應均有可能導致生產線中斷，而蒙受嚴重之財物損失。部分設備隨著電力電子技術的進步對於電力品質的要求亦相對提高，特別是半導體產業使用的機台已大多屬於敏感性設備，包括交流接觸器、可調速驅動器及可編程邏輯控制器等，對電壓驟降非常敏感。實際上供電側的事故是難以避免的，諸如設備故障、人為失誤、外物碰觸及雷擊等，因此如何去防範或改善事故所引起之暫態電力品質問題直至今日仍是被廣泛討論的議題。
本論文提出動態電力補償系統來有效地減少電力供應上的影響，同時也可以為用戶提供可靠、穩定且品質優良之電力。動態電力補償系統之操作模式被設計為兩種，分別為電力品質模式及緊急電源模式。在正常情況下，動態電力補償系統運作於電力品質模式以減少用戶側之電力品質問題，一旦動態電力補償系統偵測到發生於供電側之電壓驟降或電力中斷，動態電力補償系統將立即切換為緊急電源模式。已被廣泛應用的對稱分量法、瞬時無效功率法及克拉克轉換之綜合補償實現了動態電力補償系統之各種應用。為了驗證提出之補償系統可行性，本論文使用Matlab/Simsulink建置動態電力補償系統之程式方塊並設立多種合適情境。最後之模擬結果顯示，動態電力補償系統不僅可以改善用戶側之電力品質議題，並且可以有效地克服供電側由電壓驟降或電力中斷造成之問題。

With the rapid development of high-tech industries, the proportion of digital instruments and highly sensitive equipment used in various fields in the science park is increasing. However, the more sensitive devices are used, the higher the requirements for power supply quality. Any power supply with quality problems may lead to interruption of the production line, resulting in serious property damage. With the advancement of power electronics technology, some devices have relatively higher requirements for power quality. In particular, most of the machines used in the semiconductor industry are sensitive equipment, including AC contactors, adjustable speed drives and programmable logic controllers, which are very sensitive to voltage dips. In fact, accidents on the power supply side are unavoidable, such as equipment failures, human errors, foreign objects and lightning strikes. Therefore, how to prevent or improve transient power quality problems caused by accidents is still a widely discussed topic today.
This thesis proposes a dynamic power compensation (DPC) systems to effectively reduce the impact on power supply. At the same time, the proposed DPC system can also provide customers with reliable, stable and high-quality power. The proposed DPC is designed with two operation modes, including power quality (PQ) mode and power supply (PS) mode. In normal situation, the DPC system works in the PQ mode to mitigate power quality problems in the customer side. Once the DPC system detects a voltage sag or power interruption in the power supply side, the DPC system will immediately switch to the PS mode. The symmetrical component method, instantaneous reactive power method and Clarke transformation have been integrated to realize various applications in the DPC. In order to verify the feasibility of the proposed DPC system, this thesis builds the function blocks of the DPC system and sets up various suitable case studies using MATLAB/SIMULINK software. The simulation results show that the proposed DPC system not only improves the power quality issues in the customer side but also effectively overcomes the problems caused by power interruptions or voltage sags in the power supply side.
