Energy supply control system and method of data center

Abstract

The invention discloses an energy supply control system and method of a data center. The energy supply control method comprises the following steps: an internal combustion engine generator does work on natural gas and air to generate electric energy to supply to a garden to use, and flue gas exhausted by a tail flue is conveyed to a lithium bromide refrigerating machine through a flue-gas three-way valve to provide a heat source to the lithium bromide refrigerating machine, wherein the flue gas three-way valve is regulated according to PID parameters to control the size of opening degree, so that flue gas of the internal combustion engine generator is dynamically matched with power of the lithium bromide refrigerating machine; the lithium bromide refrigerating machine performs treatment onthe flue gas heat source exhausted by the internal combustion engine generator to generate chilled water, and the chilled water is conveyed to a cold storage tank through an outlet valve of the lithium bromide refrigerating machine, and a chilled water pump to supply cold to the data center; an electric refrigerating machine adopts a magnetic-suspension electric refrigerating unit to generate chilled water, and the chilled water is conveyed to the cold storage tank though an outlet valve of the electric refrigerating machine and the chilled water pump to supply cold to the data center. In this way, a novel energy supply mode is adopted to supply energy to the data center, so that reliability and efficiency of energy supply of the data center are improved, and therefore, an energy utilization rate is increased, and the cost is reduced.

Description

technical field [0001] The invention relates to the technical field of data center chiller systems, in particular to a data center energy supply control system and method. Background technique [0002] At present, in related technologies, commercial power is usually used to power the data center, and the power loads are mainly servers and electric refrigerator systems. However, the above methods have a very large demand on the power grid, and the quality and reliability of the power supply of the power grid will directly lead to the quality and reliability of the data center data. Among them, the data centers are mostly located in cities far away from the power supply point, and their power consumption is huge. It is bound to cause a waste of energy. Among them, the adjustment ability of the flue gas three-way valve is poor, and it is impossible to accurately control the flue gas of the bromine cooler as much as possible.
