An Automatic Single Phase Power Factor Compensator using Fuzzy and Gain Scheduling

Power quality has been much concern of many researchers these days. Power factor compensator is the main topic of this research, as it is can be alternative for increasing efficiency of power quality. Power factor (cos φ) value equal or close to 1 categorized as a good power quality. In this research, an automatic power factor compensator with various capacitor values is proposed. Fuzzy logic controller and gain scheduling are applied, in order to control power factor value maximally. Capacitor value that required can be obtained from control system of the plant. Then, some capacitors will be activated with an algorithm. The software is embedded in low-cost microcontroller which will activate specific capacitor variables as the system needed. In the end of this paper is provided data of prototype performance. Already proved, prototype can compensate power factor quality of the grid.
