Description

Distributed DC power system
Technical field
This utility model belongs to power technique fields, relates in particular to a kind of distributed DC power system.
Background technology
In existing DC power system designs, most digital devices require to realize continual power supply for power supply power-supply service.The most general technical scheme all using exchange UPS or HVDC, described exchange UPS refers to that power supply is made up of commutator, accumulator and inverter.When civil power is normal, electric current passes sequentially through commutator, inverter powers to the load, and commutator charges a battery simultaneously.And when municipal power failure or rectifier fault, making battery by control circuit automatic switchover is load supplying.This is a kind of based on double conversion routes that civil power is converted into direct current, direct current conversion exchange.This system is complex, the problem that there is reliability and inefficiency.And HVDC refers at current conversion station, alternating current is converted into unidirectional current, then transmitted to receiving a little by aerial cable.By second current conversion station, unidirectional current is converted back alternating current in reception o'clock.Although electric energy loss is less than exchange UPS but it is substantially still that a kind of double converter technique, still there is the problem that module failure rate is high.It is primarily used for the system for middle high power load.Therefore how break-through skill bottleneck, overcome the problems referred to above to be the direction that those skilled in the art need research.
Utility model content
For overcoming the problems referred to above, this utility model provides a kind of distributed DC power system.
Its concrete technical scheme used is as follows:
A kind of distributed DC power system, is made up of rectification module, static switch, main control module, isolation module, high frequency intelligent charger, rechargeable battery set, batteries management system and human-computer interaction device.Described batteries management system is installed in rechargeable battery set;The input of described rectification module connects outside mains supply, outfan is connected to load.The mains supply outside input connection of described high frequency intelligent charger, outfan are connected to the input of rechargeable battery set through isolation module;The outfan of described rechargeable battery set connects the outfan of rectification module successively through isolation module and static switch;The input of described main control module connects outside mains supply, monitoring line voltage change;The outfan of described main control module connects the shutoff of static switch and rectification module, control static switch and rectification module/open;Described main control module, batteries management system and high frequency intelligent charger connect human-computer interaction device respectively.Preferably, in above-mentioned distributed DC power system: described isolation module uses single-phase full-wave rectifer circuit.
By using this technical scheme: to load supplying after the main loop employing direct rectification module of single-phase civil power, meanwhile, set of cells is safeguarded charging by configuring high-frequency intelligent charging machine CG.City is only producing a unsteady flow through rectification module after being electrically accessed, and simplifies system structure.Utilize isolation module to isolate major loop and charger, the one direction contact of rechargeable battery set, play the effect of protection element.System reliability is greatly improved.
Compared with prior art, this utility model structure more simplifies, and when internal fault occurs in the system that ensure that, load does not has a power failure.Greatly improve the reliability and maintainability of system.
Accompanying drawing explanation
Fig. 1 is the structured flowchart of embodiment 1 of the present utility model.
Detailed description of the invention
In order to be illustrated more clearly that the technical solution of the utility model, below in conjunction with accompanying drawing, this utility model is further described.
Embodiment 1 the most of the present utility model:
A kind of distributed DC power system, is made up of rectification module, static switch, main control module, isolation module, high frequency intelligent charger, rechargeable battery set, batteries management system and human-computer interaction device.Described batteries management system is installed in rechargeable battery set;The input of described rectification module connects outside mains supply, outfan is connected to load;
The mains supply outside input connection of described high frequency intelligent charger, outfan are connected to the input of rechargeable battery set through isolation module;The outfan of described rechargeable battery set connects the outfan of rectification module successively through isolation module and static switch;
The input of described main control module connects outside mains supply.The outfan of described main control module connects static switch and rectification module, control static switch and the close/open of rectification module;Described main control module, batteries management system and high frequency intelligent charger connect human-computer interaction device respectively.Wherein, isolation module uses single-phase full-wave rectifer circuit.
In practice, its work process is as follows:
When line voltage is normal, the direct rectified module converter of 220V civil power is unidirectional current and is transferred to load two ends to load supplying.Now, rechargeable battery set is charged safeguarding by charger through isolation module.Simultaneously, main control module realizes the monitoring to mains supply by parts such as built-in voltage sensor, current sensors, and line voltage, mains current, rechargeable battery set total voltage, monomer battery voltage, charging current and system mode are digitized display by man machine interface.
When main control module detects line voltage > 245V, it is determined that high voltage occurs in civil power, and main control module sends alarm signal by HMI human-computer interaction device to operator;Main control module is closed rectification module isolation civil power and opens static switch simultaneously, transfers to and to load supplying and simultaneously closes off charger with rechargeable battery set.
And when main control module detects line voltage < 240V, it is determined that civil power recovers from high voltage, and main control module controls rectification module and opens, closes static switch, opens charger, recovers the charge maintenance to rechargeable battery set.Staff's manual Alerts Off on HMI human-computer interaction device simultaneously.
When main control module detects line voltage < 190V, it is determined that low-voltage occurs in civil power, and now main control module sends alarm signal by HMI human-computer interaction device;Close rectification module isolation civil power, open static switch, transfer to and to load supplying and simultaneously close off charger with rechargeable battery set.
And when main control module detects line voltage > 198V, it is determined that civil power recovers from low-voltage, and main control module controls rectification module and opens, closes static switch, opens charger, recovers the charge maintenance to rechargeable battery set.Staff's manual Alerts Off on HMI human-computer interaction device simultaneously.
The above; it is only specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; any those skilled in the art is in technical scope disclosed in this utility model; the change that can readily occur in or replacement, all should contain within protection domain of the present utility model.Protection domain of the present utility model is as the criterion with the protection domain of claims.
