Power Quality Improvement In Distribution Systems Using Facts Devices
Journal Title: International Journal of Science Engineering and Advance Technology - Year 2016, Vol 4, Issue 10
Abstract
The quality of available supply power has a direct economic impact on industrial and domestic sectors which affects the growth of any nation.This paper proposes an algorithm to produce reference voltage for a distribution static compensator (DSTATCOM) working in voltage-control mode. The proposed plot displays a few favorable circumstances contrasted with customary voltage-controlled DSTATCOM where the reference voltage is subjectively taken as 1.0 p.u. The proposed plot guarantees that unity power factor (UPF) is accomplished at the heap terminal amid ostensible operation, which is unrealistic in the customary technique. Additionally, the compensator infuses bring down currents and, hence, reduces losses in the feeder and voltage-source inverter. Advance, a sparing in the rating of DSTATCOM is accomplished which builds its ability tomitigate voltage sag. About UPF is kept up, while managing voltage at the load terminal, amid load change. The state-space model of DSTATCOM is consolidated with the deadbeat prescient controller for quick load voltage direction amid voltage unsettling influences. With these components, this plan permits DSTATCOM to handle control quality issues by giving power factor correction, consonant disposal, stack adjusting, and voltage direction in view of the load prerequisite.
