Embodiment
In order to be better understood by technical scheme, the invention will be further described below in conjunction with the accompanying drawings.
As shown in Figure 1 to Figure 3, a kind of HVDC uninterruptible power systems for intelligent grid, including HVDC are uninterruptedly supplied
Power supply, emergency lighting module, micro computer monitoring module, electric energy tariffing module and fire detection module；Micro computer monitoring module includes

The first power supply AC1 and second source AC2, the first power supply AC1 are included by switching K1 connection display apparatus modules, second source AC2 according to
Secondary to pass through the 3rd rectifier, inverter switchs K2 connection display apparatus modules.Node between 3rd rectifier and inverter passes through
Battery E2 is grounded.
UPS uninterrupted power sources add inversion link compared with dc source, and the circuit structure of inverter is than rectification
It is more than device complexity several times.Meanwhile, power component-large power triode of inversion is operated on off state, when bearing the change of current
Overvoltage and power attenuation.Although the reverse proof voltage of inverter power component several times higher than Dc source power element,
The selection of other components is also more more strict than dc source, and UPS uninterrupted power source totle drilling costs are equivalent capability DC currents
Several times more than.But for these reasons, the safe and reliable coefficient of UPS uninterrupted power sources is far away from dc source.
It is as shown in Figure 3 for UPS uninterrupted power source structures：, can be by battery when AC1 power interruptions or rectifier are damaged
E2 is continued to electricity consumption load supplying by inverter；But such as there is battery, inverter to damage, AC1 power off times are long (to exceed electricity
Tank discharge capacity) etc. phenomenon when, ups power will stop powering to the load.Because inverter output voltage has waveform, phase
Difference in terms of position, frequency so that the output end of inverter can not be in parallel with other power supplys (including other inverters).
I.e.：Before K1 is switched off, K2 switches can not be closed, and otherwise accident will be made further to expand.Now, the confession of load is such as recovered
Electricity, it is necessary to first disconnect K1 switches, then put into K2 switches, can just make load realize the operation of access stand-by power supply.UPS is uninterruptedly electric
Source automatically, incessantly can not be switched on another power supply from a power supply, UPS uninterrupted power sources is not accomplished real meaning
" uninterrupted power supply " of justice, it is impossible to meet requirement of the specific loads to high reliability of powering.And dc source as shown in Fig. 2 it
In the absence of waveform, phase, the difference of frequency.After two dc sources are by diode-isolated, it is possible to directly in parallel, jointly to
Load supplying.So, whichever power supply (either direct current or alternating current) power failure or failure, another power supply can
Automatically, without interruption, relatively independently to electricity consumption load supplying.With electric loading due to by two relatively independent power supplys simultaneously
Ground, power standby each other, " uninterrupted " power supply of real meaning is obtained using electric loading, so as to further increase power supply
Reliability, reduce economic loss caused by system dead electricity.
Because direct current does not have the zero crossing of electric current, voltage；And supply line has inductance, therefore the cutout of switch
Ability decreases.For the circuit that operating current is larger, capacity or the increase by one that should increase switch are continuous as shown in figure (5)
Link is flowed, the need for meeting switch cutout abilities.
As shown in figure 4, HVDC uninterruption power sources include uninterrupted power supply circuit and freewheeling circuit, the freewheeling circuit
Circuit structure be：The output end of uninterrupted power supply circuit passes sequentially through switch K3, the diode D3 of anti-phase connection, electric capacity C2,
K4 ground connection is switched, diode D3 is connected in parallel resistance R, and the node between diode D3 and switch K3 is HVDC uninterrupted power supplies electricity
The positive pole in source, the negative pole ground connection of HVDC uninterruption power sources.
As shown in figure 5, emergency lighting module includes the first high-frequency inverter being connected with HVDC uninterruption power sources, the
One output end of one high-frequency inverter passes through the 1st pin of inductance L1 connection electricity-saving lamps, another output end connection electricity-saving lamp
The 2nd pin, electric capacity C1 is connected between the 3rd pin of electricity-saving lamp and the 4th pin.
For the resistive illuminator such as incandescent lamp, as long as the virtual value of DC voltage is identical with alternating voltage, direct current
Source can just be used without any transformation instead of AC power for these loads.
For gas discharge lighting lamp tool, such as fluorescent lamp, mercury vapor lamp, conventional industrial frequency reactor (ballast) is used as current limliting
Element.Because reactor can not limit DC current, used it is thus impossible to which dc source is connected in these light fixtures.But with
The development of electronic technology, people have invented electric ballast and electricity-saving lamp.The circuit structure of electric ballast and electricity-saving lamp such as Fig. 5
Shown, it is that, not by Industrial Frequency Transformer, direct rectifying and wave-filtering becomes direct current by 220V alternating currents；Direct current passes through triode
It is reverse into the alternating current of high frequency；Alternating current produces a high voltage by LC series resonant circuits in lamp tube ends, makes fluorescent tube two
Discharged between pole, reach the purpose for starting fluorescent tube；After fluorescent tube starts, the electric current for flowing through fluorescent tube is limited by radio-frequency rector.Electronics
Ballast compared with traditional ballast, with without stroboscopic, noiseless, small volume, it is lightweight, energy-conservation and can realize that low-voltage is opened
Dynamic the advantages of.Electric ballast or electricity-saving lamp in this way, add 220V AC or DC voltages before rectifying and wave-filtering, it is rectified after
DC voltage is essentially identical, and does not influence the effect of high-frequency inversion.Therefore, using electric ballast or the light fixture of electricity-saving lamp,
It can be connected on 220V dc sources.Using the gas discharge light fixture of power frequency ballast, only power frequency ballast is changed into electronics
After ballast, light fixture could be connected on 220V dc source.
As shown in fig. 6, the electrical block diagram of host module includes：Second be connected with HVDC uninterruption power sources
High-frequency inverter, the second high-frequency inverter connects rectifying and wave-filtering voltage-stablizer, rectifying and wave-filtering voltage-stablizer connection main frame by transformer
Module.
Voltage-stabilized power supply used in micro-mainframe computer uses switching mode voltage stabilizer, and its common structure is as shown in Figure 6：
It is, not by Industrial Frequency Transformer, to be rectified into direct current by alternating current；Direct current becomes the alternating current of high frequency by inversion；It is high
The alternating current of frequency is isolated by high frequency transformer, rectifying and voltage-stabilizing becomes the low-voltage dc power supply that microcomputer device is used.It is to pass through
The ON time or switching frequency for changing switch triode reach the purpose of voltage stabilizing.Switching mode voltage stabilizer and tandem type voltage stabilizing electricity
Source is compared, and is had：Small volume, efficiency high, no industrial frequency transformer, permission supply voltage have the advantages that larger fluctuation range.Together
Electric ballast is the same, and master microcomputer power supply can be connected on 220V dc sources.
Element in computer display, in addition to anti-magnetized coil, field-discharge resistance use AC power, other elements are used
Through the direct current after switching power supply voltage stabilizing.Wherein, the process of demagnetization is：During start, due to the same room temperature of field-discharge resistance temperature,
Resistance very little (about 20 Ω), produces powerful alternating current (5-10A) in anti-magnetized coil.On the one hand this electric current, makes demagnetization
Resistance heating, resistance is incrementally increased to 20-100K Ω or so, and electric current is gradually reduced to 2-10mA；On the other hand, gradually reduce
Alternating current, produce the alternating magnetic field that gradually reduces, eliminate the remanent magnetism in kinescope.As demagnetization loop is connected on direct current
On source, kinescope unidirectional magnetiztion can be made and damaged.Therefore, to display, we can take two kinds of methods to transform it.
First method is：Display is connected on UPS uninterruption power sources, the AC power power-off used when display
When, stand-by power supply can be automatically engaged interior in short-term.Because display is intended only as an interface of human-computer exchange, its short supply interruption
Do not result in the loss of data in microcomputer, do not interfere with the safe operation of process units more.Display is transformed in this way, it is excellent
Point is can not to change any wiring in display, has the disadvantage, when the AC power power-off that display is being used, to make
Into the of short duration dead electricity of display.Second method is：The anti-magnetized coil and field-discharge resistance of display are individually drawn, by display its
Its loop is connected on 220V dc sources.When display needs demagnetization, by anti-magnetized coil and the of short duration incoming transport of field-discharge resistance
Power supply.
HVDC uninterruption power sources by DC-DC change-over circuits to electric energy tariffing module and fire hazard monitoring module for power supply,
As shown in fig. 7, the structure of DC-DC change-over circuits includes：The positive pole of HVDC uninterruption power sources passes sequentially through switch S, inductance L
And switch S0 ground connection, the negative pole ground connection of HVDC uninterruption power sources, the node between S and inductance L is switched by reversely connecting
Some branch roads, branch route one electric capacity and one are connected with node between the diode D4 ground connection connect, switch S0 and inductance L
Individual resistor coupled in parallel is formed by connecting.Branch road connects PWM controller, PWM controller controlling switch S, S0, S1 by backfeed loop respectively
Until Sn shut-off and conducting.
DC-DC change-over circuits export n voltage, and wherein n is positive integer.Meet electric energy tariffing module and fire hazard monitoring simultaneously
The power supply requirement of instrument and meter needed for module.The output that single inductance completes multiple voltages is employed simultaneously, it is simple in construction, into
This is low.
Although above-mentioned the embodiment of the present invention is described with reference to accompanying drawing, not to present invention protection model
The limitation enclosed, one of ordinary skill in the art should be understood that on the basis of technical scheme those skilled in the art are not
Need to pay various modifications or deform still within protection scope of the present invention that creative work can make.
