The water cooling module 4 includes a condenser 5, a condensate pump 6, a first delivery pipeline 7, and a heat recovery pipeline 8. The condenser 5 and the condensate pump 6 are arranged on the first delivery pipeline 7 and are connected through the first delivery pipeline 7. The water inlet of the first delivery pipeline 7 is connected to the steam turbine exhaust system, the water outlet of the first delivery pipeline 7 is connected to the thermal cycle system of the power plant, and the water inlet of the heat recovery pipeline 8 is connected to the portion of the first delivery pipeline 7 located behind the condensate pump 6. The water outlet of the heat recovery pipeline 8 is connected to the thermal cycle system of the power plant. The water-cooled data center group 2 is arranged on the heat recovery pipeline 8. The water-cooled data center group 2 is cooled by the cooling medium flowing in the heat recovery pipeline 8. The cooling medium in the heat recovery pipeline 8 is water. The air-cooling module 9 includes a refrigeration unit 10, a fan 11 and a second delivery pipeline 12.

The air-cooled data center group 3 is arranged on the second delivery pipeline 12. The air-cooled data center group 3 is cooled by the cooling medium flowing in the second delivery pipeline 12. The cooling medium in the second delivery pipeline 12 is air.

[0024] The large data center group and power plant energy efficiency complementary system of this embodiment adopts a condensate pump 6 to deliver low-temperature condensate to water-cool the water-cooled data center group 2, and adopts a fan 11 to deliver cold air to air-cool the air-cooled data center group 3. It has multiple cooling methods. The condensate heated by the water-cooled data center participates in the thermal cycle of the power plant to recover heat, thereby improving the power generation efficiency of the power plant and avoiding energy waste. At the same time, the data center group is close to the power plant, and has the advantages of high reliability, low cost and high performance.

[0025] Specific implementation method 2: Combination Figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that a first valve 13 is provided at the water outlet of the first delivery pipeline 7, and a second valve 14 is provided at the water inlet of the heat recovery pipeline 8. When the first valve 13 is closed and the second valve 14 is opened, all the water in the first delivery pipeline 7 flows to the heat recovery pipeline 8, and then flows from the heat recovery pipeline 8 to the thermal cycle system of the power plant. When the water-cooled data center group 2 needs to be repaired, the first valve 13 is opened and the second valve 14 is closed, and all the water in the first delivery pipeline 7 flows to the thermal cycle system of the power plant. The other components and connection relationships are the same as those of the first embodiment.

[0026] Specific implementation method three: Combination Figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that it also includes: a heat storage device 15, which is arranged on the heat recovery pipeline 8. The heat storage device 15 is arranged in parallel with the water-cooled data center group 2. By controlling the hot water entering and discharging the heat storage device 15 to match the parameter changes of the condensed water in the pipeline downstream of the first valve 13, the condensed water heated by the water-cooled data center group 2 is accurately matched and recovered according to the operating parameters of the power plant under different loads, so that the system of the present invention has the best energy efficiency. The heat storage device 15 can be a water tank, a water tank, etc. The other components and connection relationships are the same as those of the first embodiment.

[0027] Specific implementation method four: Combination Figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that a plurality of first regulating valves 16 are arranged in parallel on the heat recovery pipeline 8. One first regulating valve 16 corresponds to one data center in the water-cooled data center group 2. The cooling flow of different data centers in the water-cooled data center group 2 is controlled by the first regulating valve 16. Since the real-time computing volume of different data centers is different, the control of the cooling flow can realize the on-demand precise control of the water cooling volume of different data centers. The other components and connection relationships are the same as those in the first embodiment.

[0028] Specific implementation method five: Combination Figure 1This embodiment is described. The difference between this embodiment and the first embodiment is that it also includes: a cold storage device 17, which is arranged on the part of the second delivery pipeline 12 between the refrigeration unit 10 and the fan 11. A part of the excess cold of the cold air is stored by the cold storage device 17 and the cold storage device 17 releases the cold when the cold demand of the air-cooled data center group 3 increases, thereby realizing accurate real-time control of the total air demand of the air-cooled data center and making the heat-driven refrigeration unit operate at the rated working condition of the design point, ensuring that the heat-driven refrigeration unit has high efficiency and long service life. The cold storage device 17 can be a refrigerator, an insulation box, etc. The other components and connection relationships are the same as those of the first embodiment.

[0029] Specific implementation method six: Combination Figure 1 This embodiment is described. The difference between this embodiment and the first embodiment is that a plurality of second regulating valves 18 are arranged in parallel on the second delivery pipeline 12. One second regulating valve 18 corresponds to one data center of the air-cooling data center group 3. The second regulating valve 18 can control the air cooling flow of different data centers in the air-cooling data center group 3. Since the real-time computing volume of different data centers is different, controlling the cooling flow can realize the on-demand precise allocation control of the air cooling volume of different air-cooling data centers. The other components and connection relationships are the same as those of the first embodiment.

[0030] Specific implementation method seven: Combination Figure 1 This embodiment is described. The difference between this embodiment and the specific embodiment 1 is that it also includes: an energy storage module 19, which is arranged on the second transmission pipeline 12. The energy of the energy storage module 19 can be used to heat the cold air, so that the cold air becomes low-temperature air, which is easier to heat. It can also absorb the excess electric energy output by the power plant during the valley power period, which is conducive to deepening the peak-shaving depth of the power plant's participation in the peak-shaving of the power grid, making the power plant more flexible in responding to the dispatch of the power grid, and also enabling the power plant to have better power generation benefits. The other components and connection relationships are the same as any one of the specific embodiments 1 to 6.

[0031] Specific implementation method eight: Combination Figure 1 This embodiment is described. The difference between this embodiment and the seventh embodiment is that the energy storage module 19 includes a solid electric heat storage device 15, which is electrically connected to the power generation module 1, the refrigeration unit 10 is a heat-driven refrigeration unit, and the second transmission pipeline 12 is a self-circulating pipeline. The excess electric energy output by the power plant generator is converted into heat energy to heat the low-temperature wind at the outlet of the air-cooled data center group 3 to high-temperature wind, and the high-temperature wind enters the heat-driven refrigeration unit for heat exchange, driving the heat-driven refrigeration unit to operate and provide external cooling. At the same time, the solid electric heat storage device 15 stores excess heat energy beyond the rated operation of the heat-driven refrigeration unit. During the level and peak periods other than the power supply valley, the solid electric heat storage device 15 releases heat energy to drive the heat-driven refrigeration unit to operate and provide external cooling. Other components and connection relationships are the same as those of the seventh embodiment.

[0032] Working principle of this implementation:

[0033] First, close the first valve 13 and open the second valve 14. Driven by the condensate pump 6, the cold water in the first delivery pipeline 7 flows to the heat recovery pipeline 8, and then adjust each first adjustment to adjust the cooling flow of each data center in the water-cooled data center group 2. The cold water flows to the power plant heat exchange system after being heated in the data center. The cold air generated by the heat-driven refrigeration unit flows to the air-cooled data center group 3 under the drive of the fan 11. Adjust each second regulating valve 18 to adjust the cooling flow of each data center in the air-cooled data center group 3. The cold air flows to the solid electric heat storage device 15 after being heated by the air-cooled data center group 3. The solid electric heat storage device 15 heats the air again and makes it flow to the heat-driven refrigeration unit for heat exchange, thereby continuously outputting cold air to cool the air-cooled data center group 3.
