Supplying power to the seawater desalination combined load bank 60 when the production power during the trial operation or the normal operation exceeds the demand power (S100);
A step S200 of allowing the vacuum chamber 70 and the fresh water storage tank 100 in the seawater desalination system 300 to have a predetermined vacuum pressure by a single vacuum pump 110;
Inside the vacuum chamber (70), the surface water is heat-exchanged with the refrigerant in the sea water temperature difference generation system 200, the temperature is raised, the supply step up to a predetermined water level (S300);
Operating the electric heater 71 inside the vacuum chamber 70 to heat the surface water to a predetermined temperature to form fresh water vapor of the surface water (S400);
Condensing the fresh water vapor by heat exchange with the deep water and the heat exchanger (90), which are cold and heat-exchanged with the refrigerant in the seawater temperature difference generation system (S500);
Condensed fresh water is stored in the fresh water storage tank 100 (S600); made, including,
The vacuum pump 110 of the step S200, the electric heater 71 of the step S400 is
The power generated at the load performance test of the generator 15 in the seawater temperature difference generation system 200 and the power at the time of generating surplus power are transmitted and driven through the load bank 60 connected for the performance test of the generator 15.
In step S500,
The surface water concentrated by evaporation is used for salt production and mineral extraction, and the control method of the seawater desalination combined load bank system for commissioning and utilizing surplus power. delete delete
