The paper considers a closed-loop power supply for an autonomous object that is operated remotely. The power to the object is delivered via a direct current (DC) power transmission line representing a three-wire cable. The length of the cable is considered to be 8 km. The model in MATLAB Simulink has been created to investigate the essentials of the power supply operation and adjust the voltage controller. To compensate the voltage drop across the cable (over 500 V) the current signal correction was introduced. This correction proved to be a reliable method to provide a stable load voltage of 1200 V±2% in steady-state operating modes of electric equipment within the autonomous object structure. This will significantly enhance the overall performance of the equipment that is placed on the considerable distance from the power supply.
