The invention provides an operation control system of a superconductive energy pipeline. The operation control system comprises the superconductive energy pipeline, liquid storage tanks connected withthe two ends of the superconductive energy pipeline, an LNG immersed pump in pipeline connection with one end of one liquid storage tank, a refrigeration unit in pipeline connection with the LNG immersed pump, and a heat exchanger in pipeline connection with the refrigeration unit. The heat exchanger is connected with the other liquid storage tank through a pipeline. when the LNG demand quantityis reduced, excessive LNG is reversely conveyed back to the starting point, a pipeline adopted for reverse conveying is a common conveying pipeline, and in order to avoid that the temperature rise inthe conveying process is too large, a mixed working medium refrigerator is adopted for cooling. Finally, the reversely conveyed LNG enters the heat exchanger to be subjected to heat exchange with immersed pump before entering the liquid storage tanks, the LNG enters the liquid storage tanks after being further cooled, and the LNG conveying amount is adjusted on the premise that electric power is normally conveyed.
