PENGGUNAAN KAPASITOR BANK UNTUK MEMPERBAIKI FAKTOR DAYA DAN MENGURANGI RUGI-RUGI DAYA MENGGUNAKAN FUZZY LOGIC CONTROLLER DI QUEST HOTEL KUTA BADUNG

Abstract

Quest Hotel Kuta is a place of business engaged in lodging services. To support operational
needs, the hotel uses electrical equipment, most of which are inductive. The use of high inductive
loads can produce high reactive power, depending on the power factor because the active power
obtained from the installed power will be less. Based on the measurement results at Quest Hotel Kuta
the measured power factor is 0.70, while PLN charges the excess cost of kVARH to the customer if
the average power factor is less than 0.85. To be able to improve the low power factor can be done by
using a capacitor bank, the capacitor uses the reactive power required at the inductive load. Changing
the power factor in consumers can change. To equalize the power change factor, the capacitor bank is
assembled to work multiple steps / multi steps. Multi-step capacitor banks consist of several capacitors
with the same or different capacities. Based on the results of measurements before using the fuzzy
logic method, the obtained power factor is 0.70 to 0.74 while the capacitors are installed from 12.5
kVAR to 25 kVAR. After using the fuzzy logic controller method the power factor obtained is 0.80 to
0.87 and capacitors using the 13.1 kVAR to 22.4 kVAR method. Whereas the power losses before
using the fuzzy logic controller method are 26220.5 watts. After using the fuzzy logic controller
method, the power losses incurred were 23214.45 watts.
