This paper compares line losses between voltage controlled before and after using power conversion device in AC feeding system. For this purpose, the power conversion device using the AC feeding system from the grid voltage control procedures and criteria were presented. And AC feeding system was modeled in order to simulate various condition. Through simulations, voltage controlled before and after the line losses of each vehicle tracks location were compared. When a train runs with maximum power, train’s voltage of 22.91kV vehicle before control was controlled to 25.08kV, it was able to reduce line losses to 16.27%. And when three vehicles load that is peak loading condition of feeder section was input line losses was reduced to maximum 49.11%.
