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.

As shown in Figure 1, electric power system comprises A and B duplex feeding, and the A road supplies power from electrical network A power taking, converts three-phase electricity into by transformer, offers terminal equipment AC-DC power supply master ac input end after the AC distribution part converts three-phase electricity into single-phase alternating current.The power supply of B road is from electrical network B power taking; Convert three-phase electricity into after automatic change-over output by transformer; Diesel engine generator is supplied power in support and is connected with automatic change-over; The output three-phase electricity passes to UPS through AC distribution, and battery is that UPS provides the reserve power supply, and UPS output offers terminal equipment AC-DC power supply backup ac input end after AC distribution converts single-phase alternating current into.Terminal equipment AC-DC power supply is the input of double cross stream, supports the power module (seeing accompanying drawing 2 in detail) of output-parallel.

During operate as normal, the A road provides electric power as primary input, and the B road is in the Hot Spare state as the backup input.If electrical network A breaks down, terminal equipment AC-DC power supply switches to backup and exchanges input service, and B provides electric power by electrical network.If it is normal that electrical network A recovers, terminal equipment AC-DC power supply automaticallyes switch back to lead and exchanges input service, has electrical network A that electric power is provided.If between electrical network A age at failure; Electrical network B also breaks down, and automatic change-over can automatically switch to by the diesel engine generator power supply, but because the diesel engine generator startup needs a period of time (about 10 minutes); This moment, battery was that UPS provides the energy, and UPS is that terminal equipment provides electric power.After diesel engine generator starts, be that UPS provides the energy just by diesel engine generator, UPS is that terminal equipment provides electric power.Simultaneously terminal equipment AC-DC power supply is except that the input of double cross stream, the direct current output-parallel, and the N+1 Redundancy Design, when a power supply broke down therein, assurance equipment normally moved.Through multiple duplication Redundancy Design as above, guaranteed the stable reliably and with long-term operation of core data center feed system.

Accompanying drawing 2 is the interior partial detailed designs block diagram of frame of broken lines in the accompanying drawing 1, i.e. terminal equipment AC-DC power unit detailed design block diagram.Every AC-DC power supply inside comprises two AC-DC power supplys, and these two power supply inputs connect different alternating currents respectively, and output-parallel is redundant, uses as two alternating current input power supplyings.Two-way exchanges and is input as active and standby design, and main road exchanges just often, main road work, and another road Hot Spare, when main road was unusual, the work of backup road realized seamless switching.

Power supply AC-DC (A) comprises two power supply AC-DC (A-1) and AC-DC (A-2), and two power supplys exchange and are input as active and standby design, and AC-DC (A-1) is a main power source, and input is connected with single phase alternating current (A.C.) A, and AC-DC (A-2) is a backup battery, and input is connected with single phase alternating current (A.C.) B.Two power supply output-parallels use as a power supply AC-DC (A).The same AC-DC of power supply AC-DC (B) design configurations (A).Relatively control unit exchanges single phase alternating current (A.C.) A and backs up the state that exchanges single phase alternating current (A.C.) B and control the work of each power supply, the active and standby switching of item through detecting main road.Power supply AC-DC (A) and power supply AC-DC (B) output-parallel are realized power supply N+1 Redundancy Design.

Single phase alternating current (A.C.) A just often compares control unit and receives detection signal, controls AC-DC (A-1) and AC-DC (B-1) work then, turn-offs AC-DC (A-2) and AC-DC (B-3), and single phase alternating current (A.C.) B is in heat and is equipped with state.When single phase alternating current (A.C.) A broke down, relatively control unit was received detection signal, controlled AC-DC (A-2) and AC-DC (B-3) work then, realized uninterrupted power supply.After single phase alternating current (A.C.) A recovered normally, relatively control unit can turn-off AC-DC (A-2) and AC-DC (B-3), and control AC-DC (A-1) and AC-DC (B-1) resume work.Adopt the mode of power supply combination, realize that input of double cross stream and direct current are redundant, improved reliability, simultaneously simple and practical, cost is low, makes things convenient for dilatation

Except that the described technical characterictic of specification, be the known technology of those skilled in the art.
