Static Var Compensator Modeling with PID Control to Improve Power Factor Universitas Negeri Medan Abstract Power factor is a comparison between active power and apparent power which shows a decrease when the proportion of active power becomes smaller than apparent power. Static Var Compensator is a device that can control power factors quickly and efficiently, compensate for changes in load, and improve the quality of electrical power in industry. This SVC requires a control system to be able to adjust the reactive power provided according to load requirements. The formulation of the problem discussed in this research is what is the effect of improving the power factor, how SVC improves the power factor, and how the Proportional Integral Derivative (PID) control method works in controlling the reactive power produced by SVC, so the aim of this research is to find out the effect of the improvement power factor, knowing how PID improves power factor, knowing how PID control methods control reactive power. The research results show that improving the power factor by compensating for reactive power causes the apparent power to decrease. The SVC way of improving the power factor is by adjusting the Firing angle of the Thyristor and SVC with the PID control method can get the right Firing angle to improve the power factor with a value of 0.99 even though the load varies. The values from the calculation results with the simulation are not too different, this shows that the simulation is appropriate. By using a capacitor of 0.0163 Farad and an inductor of 0.000623 Henry, the reactive power produced by the SVC can be varied from 0 - 742198.4 VAR.
