Component level cascade control of UPFC
2000 Power Engineering Society Summer Meeting (Cat. No.00CH37134), 2002A complete three-phase UPFC model has been developed using EMTDC. A method to regulate the UPFC to improve the dynamic performance of the power system is proposed in the paper. It consists of three different control levels that have been implemented by means of a well-established digital simulation software package PSCAD/EMTDC.

การประเมินผลกระทบของ UPFC ที่มีต่อความเชื่อถือได้ของระบบไฟฟ้ากำลัง
Unified Power Flow Controller (UPFC) เป็นอุปกรณ์ทางอิเล็กทรอนิกส์กำลังประเภทหนึ่งที่สามารถควบคุมการไหลของกำลังไฟฟ้าจริง ควบคุมการไหลของกำลังไฟฟ้ารีแอกทีฟ และควบคุมระดับแรงดันที่บัสได้ เนื่องจากคุณสมบัติที่ดีในการควบคุมดังกล่าวข้างต้น จึงมีแนวคิดที่จะนำอุปกรณ์ UPFC มาติดตั้งในระบบไฟฟ้าเพื่อปรับปรุงสมรรถนะของระบบไฟฟ้ากำลัง อย่างไรก็ตามผลการปรับปรุงคุณสมบัopenaire +1 more source
Dynamic Modeling and Simulation of UPFC
2011Unified Power Flow Controller (UPFC) combines function of voltage control, power flow control and oscillation damping. Before installation to a system, analysis for interactions between UPFC and system are needed. Building up steady, transient and dynamic models by present software to realize accurate simulations of UPFC under different system ...

UPFC Modeling in the Harmonic Domain
IEEE Transactions on Power Delivery, 2006This paper outlines the extension of harmonic domain modeling to flexible ac transmission system (FACTS) devices which contain series voltage injection elements. The proposed iterative technique is capable of modeling generic combinations of series and shunt converters; representing these elements as harmonic current and voltage sources, respectively ...
