Abstract
In supporting the economic growth of a region, the role of industry is needed. The smooth running of an industry cannot be separated from the existing electrical quality, in this case, the voltage drop. The voltage drop occurs because of the influence of the load and the distance of the distribution channel which is quite far. To minimize the voltage drop that occurs, a voltage regulator that works automatically is required. In this study, Distributed Static Compensator (D-STATCOM) was used as a voltage regulator. D-STATCOM can generate reactive power and absorb reactive power according to system requirements. The system used is the Kima feeder distribution system, which is an area with many industries. The software used to simulate the installation of D-STATCOM is PSAT MATLAB 2.1.9. The simulation is carried out in two different conditions, namely the normal state and the state when there is a three-phase short circuit fault. The simulation results under normal conditions obtained that bus 73 has a voltage of 0.90302 pu after the installation of D-STATCOM increases to 0.94597 pu. Meanwhile, when the system experiences a problem, the voltage on bus 73 is 0.89790 pu. After the installation of D-STATCOM, the 73 bus voltage is 0.94010 pu.
