Abstract

Generally, Power Quality is the main concern parameter in present power system scenario, the main causes for effecting the power quality is due to either harmonic distortion, voltage imbalances, reactive power variations. There are many techniques applied to maintain this power quality in literature. In Facts family, the UPQC controller plays a key role, because it uniquely controls all the transmission parameters. The UPQC controller is combination of series-shunt converters with common dc link. The signals required for these converters are generated by reference and actual signals of bus and dc link capacitor. Phase locked loop helps to provide the phase angle sequence required to improve power factor. In addition with, this paper is implemented with extended search algorithm to better control the dc link voltage for improving power quality. Mat lab/Simulink is used to test the system conditions and performance.
