Embodiment
In order that those skilled in the art more fully understand application scheme, below in conjunction with the embodiment of the present applicationAccompanying drawing, the technical scheme in the embodiment of the present application is clearly and completely described, it is clear that described embodiment is onlyThe embodiment of the application part, rather than whole embodiments.Based on the embodiment in the application, ordinary skill peopleThe every other embodiment that member is obtained under the premise of creative work is not made, it should all belong to the model of the application protectionEnclose.
It should be noted that term " first " in the description and claims of this application and above-mentioned accompanying drawing, "Two " etc. be for distinguishing similar object, without for describing specific order or precedence.It should be appreciated that so useData can exchange in the appropriate case, so as to embodiments herein described herein can with except illustrating herein orOrder beyond those of description is implemented.In addition, term " comprising " and " having " and their any deformation, it is intended that coverCover it is non-exclusive include, be not necessarily limited to for example, containing the process of series of steps or unit, method, system, product or equipmentThose steps or unit clearly listed, but may include not list clearly or for these processes, method, productOr the intrinsic other steps of equipment or unit.
First, the part noun or term occurred during the embodiment of the present application is described is applied to following solutionRelease：
UPS distribution structures and Tier classification be it is corresponding, it is specific as shown in table 1
Table 1
| Configuration | Availability yardstick | Tier is classified |
| Capacity (N) | 1=is minimum | Tier 1 |
| Series redundancy | 2 | Tier 2 |
| Parallel redundancy (N+1) | 3 | Tier 3 |
| Dual system (2N, 2N+1) | 5=highests | Tier 4 |
Wherein：
Capacity " N "：
Also known as single system structure.In the calculating process of UPS design configurations, generally use letter " N " sets to refer to UPSMeter configuration.For example, parallel redundant system is also referred to as N+1 designs, and Dual System Design can be represented with 2N." N " can be simpleGround is defined as " need (demand) " of critical loads.In other words, that is, the power supply capacity of institute's protection equipment delivery is met.WeThe purposes of " N " can be explained with I T equipment such as RAI D (RAID) systems.For example, if memory capacity needs4 disks are wanted, and RAI d systems just include 4 disks, then it is one " N " design to claim this., whereas if RAI d systems have5 disks, and memory capacity only needs 4 disks, then is designed for " N+1 ".
In brief, N systems refer to by the one group parallel connection equal with critical loads planned capacity of single UPS module or capacityThe system that UPS module is formed.So far, such system is the most widely used configuration in UPS industries.DeskUnder small-sized UPS i.e. belong to N configuration.Equally, it is 400kW for planning and designing capacity, area is 500 square metres (5000 squaresFoot) computer floor, if using two 200kW UPS in parallel using single 400kW UPS or on common bus,So fall within N configurations.Therefore, N can be configured to the minimum requirements for regarding as critical loads power supply.Concrete structure such as Fig. 1 institutesShow.
Series redundancy configures (structure)：
Also known as " N+1 " system, but, it is completely different with the parallel redundancy configuration represented under normal circumstances with N+1.StringConnection Redundancy Design concept both do not need parallel bus, also should not modulus block capacity must it is identical, do not require that module comes from evenSame manufacturer.In the configuration, it is main or " master " UPS module is load supplying by one under normal circumstances.Meanwhile oneIndividual " series connection " or " auxiliary " UPS is that the static by-pass of main UPS module is powered.The static state of the main UPS module of the configuration requirement is otherRoad has single input circuit.This mode can be carried out in the case where retaining existing UPS to irredundant configuration beforeExpand, to obtain a certain degree of redundancy.Series redundancy structure can be obtained based on structure shown in Fig. 2, will two UPS by simultaneouslyConnection is changed to connect, and is then each UPS bypass circuit in parallel.
Parallel redundancy structure (configuration)：
In parallel redundancy allocation plan, when single UPS module breaks down, without critical loads are transformed into cityElectricity.All UPS purposes is all the influence for protecting critical loads Bu Shou city's Electrical changes and power-off.
In parallel redundancy allocation plan, multiple capacity identical UPS modules in parallel share an output bus.If" standby " electricity is at least equal to the capacity of a system module, then system is N+1 redundancies；If standby electricity is equal to twoThe capacity of system module, then system is N+2 redundancies；By that analogy.Parallel redundant system is required using the production of same manufacturerThe UPS module of identical capacity.UPS module is synchronized by the system parallel circuit plate of outside, and UPS module is also embedding in itself sometimesEnter this function.In some cases, the parallel function also electric current output between control module.Mutually communicated between each UPS module,To produce the output voltage of Complete Synchronization.The quantity of UPS module that can be in parallel on one common bus has one in logicLimit, for different UPS manufacturers, the maximum is also different.Under normal operating conditions, in parallel redundancy designUPS module uniformly shares critical loads capacity.If taken from parallel bus next module repaired (or if someModule is shut down because of internal fault), then remaining UPS module must bear the load of the UPS module to break down immediately.ByIn there is this function, therefore any one module can be removed from bus and is placed under repair, without critical loads are directly connectedIt is connected to civil power.Referring specifically to shown in Fig. 2.
Distributed redundancy structure：
The design is based on three or more UPS modules and independent input and output circuit.Independent output is totalLine is connected by multiple triplex level redundancies and STS with critical loads.UPS, distributed Redundancy Design and dual system are linked into from civil powerDesign as (will be discussed in the next section) is almost.Both schemes are each provided with concurrent maintenance function, and willSingle fault point minimize.The two most important difference is, is critical loads in the distribution structure from UPS to critical loadsThe quantity for providing the UPS module needed for redundant power circuit is different.Concrete structure is as shown in Figure 3.
Dual system redundancy structure：
Dual system, multi-channel parallel bus, dual input, 2 (N+1), 2N+2, [(N+1) ten (N+1)] and 2N are all referred toThe variant of the configuration.By this design, can set up completely now at all need not be by the UPS of load transfer to civil powerSystem.When designing these systems, each possible single fault point can be excluded as far as possible.
Fig. 4 shows a kind of variant of the configuration, and 2 (N+1), it is made up of two pallarel redundant UPS systems.Ideal situationUnder, single distribution board can be used, or even individually civil power and generator system are powered for these UPS.
Although can be configured using power system (electric power system) of the above-mentioned distribution structure to computer room, it is relatedSingle distribution structure is often used in technology, does not provide the reality that a variety of distribution structures how are supported in same unified power systemExisting mode.
