Enhancement of Transient Stability Using UPFC for 11 Bus Systems
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
FACTS devices are available, which can help Power Engineers to deal with problems like Large Signal Stability and economic Factors that gives strong incentives to raise the Stability limit of the System, depending upon the diverse conditions. Among the converter based FACTS devices Static Synchronous Compensator (STATCOM) and Unified Power Flow Controller (UPFC) are the popular FACTS devices. Unified Power Flow Controller (UPFC) is a power electronic based device that has capability of controlling the power flow through the line by controlling appropriate its series and shunt parameter. UPFC is a versatile FACTS controller that can regulate the Power Flow through the Line by controlling its Series and shunt parameters. In shunt it is having STATCOM and in series SSSC are employed can independently control the Line Power Flow. Two Converters improves the flexibility and provide additional degree of freedom in Power System. With the application of UPFC, Transient stability of the system can be improved. This Paper shows that how Transient Stability of the Inter Area system is Improved. In this paper, we analyze the transient stability of simple two area system of 11 bus test system of two area system with and without UPFC by comparing the rotor angles, voltage at buses, and angular frequency plots using the Time Domain feature in PSAT software.
