Desain dan Analisa Performansi Faktor Daya pada Pengembangan Bay Kapasitor 20 kV-20 MVAR

Abstract

With the increasing use of inductive equipment (equipment with windings) such as the use of motors, transformers, in general the power factor of the PLN system will decrease, for this reason it is necessary to compensate with the use of capacitors. Power Factor Controller (PFC) in this thesis is to use a capacitor in a 20 kV system to reduce reactive energy so that the power factor is getting better and selling energy. In the current condition, 20 kV-20 MVAR capacitor is installed with a 4-block system (50 MVAR each) with 3-phase power factor sensor in the incoming cubicle. System proposed to be developed into 12 blocks with sensors in each phase. From the simulation results it is found that the active power can be increased from 8.5W (4 step system) to 11.3 W (12 step system) at unbalanced load R123:100 ohm, L1:20 mH, L2:50 mH, L3:70 mH, C123:100µF.
