Abstract
Cross-linked polyethylene insulation (XLPE) type underground power cables used in medium and low voltage distribution systems bring out a reactive effect with capacitive character due to the constructional properties of XLPE cables. If this effect is not eliminated, it causes negative influences on losses, cost, and capacity. Therefore, this study focused on the capacitive effects of XLPE type underground cables and the appropriate compensation systems to overcome the issue on a medium voltage distribution system with 5500 m-length. The measurements taken from a medium voltage substation were compared to corresponding simulation results. As a result, a very successful match between simulation and measurements was achieved. Furthermore, a series of suggestions for establishing appropriate compensation was presented, which were expected to serve the more efficient transmission and distribution of energy. Since the need for more energy and the amount of utilization have been increasing, it is compulsory to carry out the works to decrease the loss rate of the transmission and distribution of energy.
