Abstract
Provided is an efficient power supply method of a data center. A power grid A and a power grid B are adopted to provide two paths of alternating-current input to achieve input redundancy, wherein A path of input passes through a transformer, two links of alternating-current distribution are directly transferred to an alternating-current-direct-current (AC-DC) power supply module in a terminal device, B path of input passes through the transformer and is transferred to a direct-current uninterrupted power supply (UPS) after alternating-current distribution, 380V high-voltage direct current is directly output, is subjected to direct current distribution and then transferred to a DC-DC power supply module in the terminal device, and 380V direct-current input is directly supported. The AC-DC power supply module and the DC-DC power supply module are in output parallel connection to achieve direct-current redundancy and supply power to a main board. The A path of input omits the UPS and the alternating-current distribution portion so that cost is reduced, conversion loss is reduced, and efficiency is improved. The B path of input omits a back-level DC-AC unit in the UPS and a power factor correction (FPC) circuit in the AC-DC power supply module in the terminal device so that cost is reduced, conversion loss is reduced, and efficiency is improved. Therefore, integral efficiency of a power supply system is remarkably improved, and cost of the system is obviously reduced.
Description
Technical field
The present invention relates to the Computer Applied Technology field, specifically a kind of data center high efficiency power method.
Background technology
This year; The treating capacity of digital information increases rapidly; In the face of the business demand amount that increases fast and user huge desired value to data treating capacity, amount of information exchange, can only through constantly increase data center's information technoloy equipment quantity satisfy the user to information network system technical performance, data-handling capacity, memory capacity with and the requirement aspect many such as availability.This moment, the energy consumption problem of data center just became more and more serious, and the energy consumption that sharply increases and the rising of electricity price make that data center's O&M cost is increasingly high.
To above problem, the present invention proposes high efficiency power system of a kind of data center, and the mode that adopts power of alterating and direct current to use with realizes Redundancy Design.DC power supply partly adopts the mode of HVDC, saves a lot of power conversion units, has improved whole electric power system efficient, and energy-saving effect is remarkable, and cost also decreases simultaneously.
Summary of the invention
The purpose of this invention is to provide a kind of data center high efficiency power method.
The objective of the invention is to realize by following mode, adopt electrical network A to provide two-way to exchange input with electrical network B, realize the input redundancy, wherein the process transformer is imported on the A road; Two links of AC distribution are directly passed to the inner AC-DC power module of terminal equipment, and the input of B road passes to direct current UPS through transformer behind the AC distribution, directly export the 380V HVDC; The 380V HVDC passes to the inner DC-DC power module of terminal equipment through after the DC distribution, directly supports the input of 380V direct current, AC-DC power module and DC-DC power module output-parallel; The realization direct current is redundant, is main board power supply, and the input of A road has saved UPS and AC distribution part, has reduced cost; Reduced transition loss, improved efficient, B road input has saved the pfc circuit in the level DC-AC unit and terminal equipment inside AC-DC power supply behind the UPS inside; Reduce cost, reduced transition loss, improved efficient; Therefore, the electric power system whole efficiency is significantly improved, and cost obviously descends.
The invention has the beneficial effects as follows: compare with the conventional data centers electric power system, the mode that adopts power of alterating and direct current to use with realizes Redundancy Design.DC power supply partly adopts the mode of HVDC, saves a lot of power conversion units, under the prerequisite that guarantees redundant power supply; Reduce a plurality of power conversion units, reduced loss, improved whole electric power system efficient; Energy-saving effect is remarkable, and cost reduces simultaneously.
Description of drawings
Accompanying drawing 1 is data center's tradition electric power system sketch map;
Data center's high efficiency power system schematic that accompanying drawing 2 proposes for the present invention.
Embodiment
Explanation at length below with reference to Figure of description method of the present invention being done.
With reference to the accompanying drawings, content of the present invention with instantiation its implementation and the course of work is described.
Accompanying drawing 1 is a conventional data centers tradition electric power system, and electrical network A provides two-way to exchange input with electrical network B, realizes exchanging redundant.Every road alternating current is through transformer, and AC distribution, UPS, AC distribution four processes pass to the AC-DC power module of terminal equipment and fail.The AC-DC power module is supported parallel redundancy, adopts the N+N Redundancy Design, and wherein half power supply is connected with interchange A, and second half power supply is connected with alternating-current B, and it is redundant to guarantee that terminal equipment exchanges.AC-DC power module output-parallel realizes that direct current is redundant, is main board power supply.As can be seen from the figure, transformer, AC distribution are all passed through in each road power supply; UPS (UPS inside comprises AC-DC and two links of DC-AC), AC distribution, these converting units of AC-DC power supply (AC-DC power supply inside comprises PFC and two links of DC-DC); Finally pass to load; Each converting unit all can cause power loss, causes whole electric power system efficient very low, and makes
Equipment is more, and system is too fat to move, and cost is high.
Accompanying drawing 2 still adopts electrical network A and electrical network B to provide two-way to exchange input for the high efficiency power system of data center that the present invention proposes, and realizes that input is redundant.The input of A road is through transformer, and two links of AC distribution are directly passed to the inner AC-DC power module of terminal equipment.The input of B road passes to direct current UPS through transformer behind the AC distribution, direct current UPS has saved inside back level DC-AC unit, directly exports the 380V HVDC.The 380V direct current passes to the inner DC-DC power module of terminal equipment through after the DC distribution, and the DC-DC power module is compared with the AC-DC power module, has saved the prime pfc circuit, only keeps back level DC-DC circuit, can directly support the input of 380V direct current.AC-DC power module and DC-DC power module output-parallel realize that direct current is redundant, are main board power supply.Compare with traditional electric power system, the input of A road has saved UPS and AC distribution part, has reduced cost, has reduced transition loss, has improved efficient.B road input has saved the pfc circuit in the level DC-AC unit and terminal equipment inside AC-DC power supply behind the UPS inside, has reduced cost, has reduced transition loss, has improved efficient.Therefore, the electric power system whole efficiency is significantly improved, and cost obviously descends.
Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
