The invention belongs to the field of aviation, and relates to an aero-engine complete machine test run high-voltage direct current loading system, which is characterized in that the high-voltage direct current loading system comprises a high-voltage load resistance box, a measurement and control device, an Ethernet communication cable and an upper computer, and the high-temperature-resistant cable is connected with the measurement and control device. The measurement and control device is connected with the generator controller through a motor control cable. All the load resistors pass through a protection unit in the measurement and control device, then are gathered to a bus cable and then are connected with a generator. According to the application, the programmable controller carries out logic programming before test run, so that the loading system is linked with the engine rotating speed and the throttle lever, automatic loading is realized according to fixed power and time, and closed-loop adjustment is
