Abstract

The electricity load in the industry is mostly inductive. The use of inductive loads in this large capacity can lead
to a decrease in power factor, increasing the voltage drop and power losses. One effort to improve the power
factor, reduce the voltage drop and also the power losses is done by the installation of sufficient reactive power
compensation in the system. This research was conducted on the distribution network of CHF 3 PT Bukit Asam
(persero) tbk with the largest load of induction motors. The research method is used by calculating the overall
reactive power requirement in the system so that the power factor value is greater than 0.95. The location of
reactive power compensation placement is compared between incoming feeder and subdistribution. The
parameters observed are the power factor, the magnitude of the voltage drop across each bus and the total loss
loss in the system. Calculation of parameters using ETAP 12.6 software help. Economic analysis is carried out
on the addition of such reactive power compensation. The results showed that the installation of reactive power
compensation in incoming feeder of 1300 kVAR resulted in 0.96 lagging power factor, total loss of power loss of
62.7 kW, the lowest voltage on bus 37 of 19.8 kV and installation cost of Rp. 864.000.000, -. The reactive power
compensation in subdistribution of 1304 kVAR resulted in 0.96 lagging power factor, total loss of power of 57
kW, the lowest voltage on bus 37 of 19,811 kV and installation cost of Rp. 836.680.000,.
