Voltage Improvement Using SHUNT FACTs Devices: STATCOM

Abstract- Shunt Flexible AC Transmission System (FACTS) devices, when placed at the mid-point of a long transmission line, play an important role in controlling the reactive power flow to the power network and hence both the system voltage dips and Voltage swells. This Paper represent modeling aspect of STATCOM (Static Synchronous Compansator) which correct voltage dips or voltage swell and observe Reactive power compensation during different voltage magnitude and time interval. The power circuit of a STATCOM and distribution network are modeled by using blocks from Power system block set while Control circuit modeled by simulink blocks
