An Overview Of UPFC With PSS For Power Flow Control And System Stability

The expanding industrialization, urbanization of lifestyle has prompted increasing dependency on the electrical energy. These days' power system networks are large in size, perplexing and interconnected, which comprise of many buses and numerous generators. FACTS controllers are introduced in numerous spots for enhancing the functionalities of power system. This paper explores the various FACTS controllers in particular Unified power flow controller (UPFC), its adaptability and capabilities in the power system operation and control. Additionally the Power System Stabilizer (PSS) is a supplementary excitation controller used to damp generator electro-mechanical oscillations. Within the ever changing utility condition, from power system operation and control perspective this review emphasizes the importance of UPFC and PSS. UPFC with PSS will offer improved Transient stability & Dynamic Stability of the system
