近年各國政府積極鼓勵再生及潔淨能源的使用，因此以分散式發電機組所構成的微型電網日漸興起，彈性交流輸電系統(FACTS)等電力電子設備，將大規模使用於微型電網中，FACTS能使現有的電力資源和輸電系統得到充分高效的利用，提高現有輸電網路的輸送能力。其中強化電力潮流控制器(UPFC)為功能最齊備之FACTS，由一並聯電壓源轉換器與一串聯電壓源轉換器組成，僅透過控制規律的變化，就能分別或同時實現並聯補償、串聯補償、移相等幾種不同的作用，可大幅度地改變輸電線路的潮流，增強系統阻尼，抑制次同步振盪以及提升整個電力系統的靜態穩定性和暫態穩定性。因此不僅能控制輸電線上潮流，也能同時控制匯流排電壓，改變傳輸線潮流，充分利用輸電線路的輸電能力，提高電力系統輸電能力。
本論文以串聯電壓源轉換器與並聯電壓源轉換器為基礎，建立三相110V,1kVA之可重製化FACTS小型實驗室雛型平台，可同時實現並聯補償STATCOM、串聯補償SSSC、與串並聯補償UPFC三種主要的FACTS裝置。以Simulink/PLECS軟體模擬與xPC硬體架構建立之實驗平台，交互驗證，以確保控制系统的有效性。控制策略以d-q理論為基礎，應用內外雙迴圈之解耦閉迴路控制架構，完成相關控制目標：內迴圈完成電流命令追蹤，外迴圈完成相關命令追蹤。軟體模擬與硬體實作驗證該控制架構優異之穩態與暫態性能。
關鍵詞: 彈性交流輸電系統、強化電力潮流控制器、電壓源轉換器、串聯與並聯補償、同步旋轉座標理論、內外雙迴圈之解耦閉迴路控制、實驗室雛型平台。

Due to rapid development of High-power Electronics Technology, Flexible Alternating Current Transmission System (FACTS), based on High-Power Electronic Circuits, can offer an opportunity to enhance controllability, stability, and power transfer capability of the existing system. It has becomes an important topic in the Smart Grid roadmap world wild. Among all FACTS, Unified Power Flow Controllers (UPFCs) seem to be the most comprehensive and provide the greatest flexibility with multiple control functions simultaneously.
The aim of this thesis is to develop hardware implementations of a small laboratory-scale UPFCs. The rating of this three-phase UPFCs is 110 V, and 1kVA. The power circuit consists of a shunt voltage sourced converter (VSC) and a series VSC. By proper switches reconfigurations, this UPFC can also provide shunt compensations or series compensations independently. The dynamical model of the UPFC under the synchronous reference frame will be described first. The inner/outer two-loop decoupled control strategy is studied later. The inner loop control is designed for the VSI current command tracking while the outer loop control is designed different commands following. The proposed control configuration has been validated under Simulink simulations and hardware laboratory implementations. Experimental works on various operating conditions have been conducted to verify the effectiveness of the proposed control strategy.
