Thermal power plant coupling data center integrated energy system and operation method

Abstract

The invention discloses a thermal power plant coupling data center integrated energy system and an operation method. The thermal power plant coupling data center integrated energy system comprise an absorption refrigerating unit, the absorption refrigerating unit is driven by heat of boiler flue gas of a thermal power plant, boiler steam, steam extraction of a steam turbine or steam exhaust of the steam turbine, or the absorption refrigerating unit is driven by heat lost by a cold source of a thermoelectric unit, and low-temperature cold water produced in summer is injected into a heat supply pipe network or a newly-built cold water pipe network; the absorption refrigerating unit communicates with a refrigerating user through the heat supply pipe network or the newly-built cold water pipe network, low-temperature cold water is conveyed to a heat exchange unit or a tail end fan coil of a central air conditioner of the refrigerating user, and therefore the cooling capacity of the thermal power plant is conveyed to the refrigerating user. According to the system, an existing external supply pipe network is utilized to carry out regional cooling, so that the pipe network investment with the maximum capital investment of a common regional cooling project is reduced; by means of steam turbine exhaust steam or circulating water waste heat and other cold source losses of the thermal power generating unit, the operation heat efficiency of the thermal power plant in summer is greatly improved, and unit coal consumption is reduced.
