## Abstract

The classic problem of power quality due to the use of linear and nonlinear loads is the value of the high and low power factor. To improve power quality and minimize the phase angle shifting current and voltage due to impure resistive loading can use compensator. The use of this compensator has been widely recommended to overcome this problem. In this paper, one configuration of the active compensator is designed, namely the compensator with the conventional Inverter method. This compensator uses the transformation method abc to dq to produce reference current and PLL (Phase Locked Loop) to produce a phase angle parallel to the reference voltage taken from the grid, from the combination of the two blocks the reference current will be obtained which aims to reduce the error flow which is the difference between setting signal with the actual signal, which aims to get the desired actual signal equal to the setting signal. And this compensator uses a PI (Proportional Integral) control as a simple control to overcome problems in the electric power system. This active compensator when operating, injects compensation flow into the electric power system. The load current that is closed to the voltage is inputted to the Compendator control and produces a trigger current for the inverter, where this trigger current determines the amount of compensation current. The design of the compensator aims to reduce reactive power so that it can improve the power quality of the system. The pf value (power factor) on a system that uses parallel reactive power compensators shows significant results compared to systems without the addition of compensators. The system's pf (powe factor) value rose from 0.7 to 0.9 and the apparent decrease in power from 88.9Mva to 80.1Mva.
