Abstract
Ideally, a distribution feeder should be able to assure the voltage level at the end of feeder not more or less than five percent of its nominal value as regulated in the Grid Code. However, in such circumstance where the feeder has to serve the load through a very long line with randomly load scattering characteristic, the level of voltage could be far below its allowable lower level. In some cases, the use of capacitor bank fails to solve this problem. In this paper a new breakthrough by utilizing an Intelligent Power Electronic Device to overcome voltage drop is proposed. A Voltage Restorer is introduced to install in a 20 kV distribution line of PLN Lampung to enhance its voltage profile. The simulations showed the range of voltage level is within the range of 95% – 105% of the nominal value.
