A Low-Cost Modulated Filter Compensator for Energy-Efficient Enhancement in AC Utilization Systems

The paper presents a low cost FACTS-based self adjusting power filter and capacitor compensation scheme (PF- CC). The topology and switching strategy of this scheme (developed by the first author) is controlled by self adjusting dynamic tri-loop error driver regulator. The FACTS-based compensation device is necessary in low voltage (below 1 KV) residential, commercial and small industrial loads with a substantial mixture of nonlinear arc, converter, and temporal inrush motorized loads. The proposed low cost scheme can ensure voltage stabilization, power quality enhancement, efficient utilization, and self switching and voltage flicker control. Nonlinear and temporal inrush motorized loads are mushrooming in use especially in consumer electronics, commercial and small industrial applications.
