Voltage Quality Improvement with Shunt Bank Capasitor and Transformer Tap
Journal Title: Engineering and Technology Journal - Year 2024, Vol 9, Issue 08
Abstract
Morocco Feeder Tapung Department is 20 kV feeder with the largest voltage drop in the PT. PLN (PERSERO), ULP Duri. The voltage drop was 16% of the nominal voltage. This study conducted voltage repairs on the medium and low voltage sides to strive for voltage increase to achieve standardization. The first stage of repair was to increase the tap by 5% on the secondary side of the Unit 1 distribution transformer of the Balai Pungut Substation. The second stage of repair was by placing a shunt capacitor bank with a capacity of 400 kVAR on bus 172. The third stage of repair was by increasing the tap of transformer by 2.5% and 5% on the secondary side of 32 and 13 distribution transformers. The result, after simulating the lowest voltage value on the medium voltage network is 91.69% and on the low voltage network is 90.47%. So that the voltage value obtained after performing the above repair measures resulted in voltage repair that has met the standard SPLN 1: 1987 which is 5 % and -10% against nominal voltage.
