Abstract
The IPFC (Interline Power Flow Controller) and UPFC (Unified Power Flow control) among the FACTS devices aimed to the power flow control .power system stability plays a vital role in the factor of reliability and power quality. Power quality mainly depends on the compensation of reactive power and level of voltages. In past the capacitive banks are used to compensate these parameters. Recent advances in FACTS Controllers improves the power system stability. In this paper, modelling and interfacing of facts controllers discussed in real time power systems. Simulations investigate the effect of UPFC and IPFC in power systems by series injected voltage and reactive power support. Finally the simulink results have been presented to indicate the reactive power support and improvement in transfer capability of lines.
