The power supply system is characterized in that a power supply channel is provided for the data center, and a power distribution unit and a charging unit are respectively connected onto an automatic change-over switch; an N+N redundant power mode is adopted for a power module of a server, a main power module is an AC-DC power module, and a backup power module is a DC-DC power module; main input is directly transmitted to the AC-DC power module via the power distribution unit, and backup input is transmitted to a battery via the charging unit and then is transmitted to the DC-DC power module; and a monitoring unit is arranged on a cabinet, and a monitoring power source is respectively connected with the AC-DC power module and the DC-DC power module. Compared with the prior art, the power supply system has the advantages that full-redundant power supply for devices of the server is implemented by the single power supply channel, the quantity of the devices is reduced, the reliability is improved, the initial investment to the data center is decreased, and the operating cost is lowered.
Description
Technical field
The present invention relates to data center's design field, be specifically related to a kind of data center electric power system.
Background technology
Data center's tradition two-way redundancy electric power supply system, for realizing supplying power with double circuit, need two-way to exchange input, the input of every road all needs independent diesel engine generator, automatic change-over, power supply unit, uninterruptible power system UPS and battery unit, number of devices is many, reliability is low, and initial outlay is high, and operation maintenance cost is high.The server power supply module is the parallel current-sharing pattern, and two power supply mean allocation bearing powers all are in than light condition during normal operation, and utilance is low, and power supplying efficiency is low.
Along with the arrival in cloud computing epoch, as the platform of cloud computing, Constructing data center is greatly developed.And how data center realizes that as the large electricity consumer colleges and universities are energy-conservation, also obtains extensive concern.Highly reliable also is one of the key index of data center.Reduce simultaneously number of devices, reduce initial outlay, cutting operating costs also is focus in the Constructing data center.
Summary of the invention
For above problem, the present invention proposes a kind of data center electric power system, uses a circuit-switched data center feed to realize the power supply of server apparatus full redundancy; Active and standby input improves the power utilization rate, realizes energy-efficiently, and simultaneously active and standby input can regularly be switched, the prolongation power source life; Minimizing equipment usage quantity improves reliability, reduces initial outlay and operation cost.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of data center electric power system provides one tunnel power supply in data center, connects respectively power supply unit and charhing unit on automatic change-over; The server power supply module is adopted as the N+N redundant power supply modes, and main power source module is the AC-DC power module, and the backup battery module is the DC-DC power module; Primary input is directly passed to the AC-DC power module by power supply unit, and the backup input passes to battery by charhing unit, and then passes to the DC-DC power module; At rack monitoring unit is set, monitoring power supply is connected with the DC-DC power module with the AC-DC power module respectively.
The invention has the beneficial effects as follows: in data center, only use one tunnel power supply to realize the power supply of server apparatus full redundancy, comprise active and standby input, oil machine backup, battery backup and power supply redundancy; Active and standby input improves the power utilization rate, and colleges and universities are energy-conservation, and simultaneously active and standby input can regularly be switched, and prolongs power source life.Relatively traditional two-way redundancy electric power supply system does not use UPS, and only needs one the tunnel to exchange input, road binders machine backup and distribution system, and number of devices reduces, Reliability Enhancement, and reduced data center's initial outlay, cut operating costs.
Description of drawings
Data center's electric power system that accompanying drawing 1 proposes for the present invention.
Embodiment
With reference to the accompanying drawings, content of the present invention with instantiation its implementation and the course of work is described.
The data center's electric power system that proposes for the present invention in the accompanying drawing 1, the server power supply module is the 1+1 active-standby mode, and main power source module is the AC-DC power supply, and the backup battery module is the DC-DC power supply, the main power source module output voltage is a little more than backup battery module output voltage, such two power supplys output passes through or door connects, and realizes active and standby power supply, when two power supplys are all normal, main power source work is load supplying, backup battery is in holding state, and during mains power failure, backup battery is load supplying.
Data center provides one road Alternating Current Power Supply, provide input by automatic change-over and power supply unit for main power source module such as figure, after automatically transforming switch, input is provided and is the battery unit charging for the backup battery module through charhing unit simultaneously, realize that server apparatus supplies power with double circuit and the battery backup.Diesel engine generator is connected with automatic change-over simultaneously, for system provides the oil machine backup.Electric power system specific works process is as follows:
When the interchange input is normal, diesel engine generator is in Status of Backups, exchange input and provide input through automatic change-over and power supply unit for main power source, after automatic change-over, exchange input and provide input through charhing unit for backup battery simultaneously, be simultaneously the battery unit charging, this moment, two power modules were all normal, main power source work, the backup battery standby, battery unit is in floating charge state.
When exchanging input fault, main power source quits work without input, backup battery work is load supplying, backup battery provides input by battery unit, and diesel engine generator begins to start simultaneously, and automatic change-over switches to diesel engine generator input is provided, the battery unit capacity need guarantee to surpass diesel engine generator start-up time, after diesel engine generator starts, for main power source provides input, main power source work, the backup battery standby is that the battery charging replenishes electric power by charge power supply simultaneously.
When exchanging input and diesel engine generator simultaneous faults, battery unit can be the electric power that server apparatus provides certain hour, is convenient to normal shutdown behind the backing up data by server device.
Supply power with double circuit with conventional data centers and to compare, only need one tunnel power supply namely can realize inputting master-slave back-up, the full redundancy power supply is provided simultaneously, comprise that oil machine backup, battery backup, power module are redundant.And compare with the conventional data centers system of supplying power with double circuit, number of devices has remarkable minimizing, the electric power system Reliability Enhancement, and initial outlay reduces, and operation maintenance cost reduces.
Because the server apparatus power module is in active-standby mode for a long time, electric power system provides monitoring unit, can regularly switch the main power supply module, prevents the primary module long-term work, and the situation of the long-term standby of backup module prolongs power supply useful life.
In addition because power module is active/standby mode, during normal operation load heavier, utilance is high, power supplying efficiency is high.
