Description
Technical field
It is automatic more particularly, to a kind of distribution of the aerial nets of A+ regions 10kV the present invention relates to the field of power distribution of typical rack
Change terminal to layout planing method.
Background technology
According to current overall present situation, the power supply reliability of aerial net is significantly lower than cable system.Therefore, from reliability requirement
Speech, the distribution power automation terminal configuration standard of aerial net should be higher than that cable system.
On the other hand, because " three is distant " terminal typically uses fiber optic communication mode, aerial net fibre optic installations can use peg
Mode realizes that enforcement difficulty and cost are relatively low, and cable system fibre optic installations are then frequently necessary in no comb and hole position resource
Shi Caiyong digging direct-buried modes, enforcement difficulty and cost are higher (containing engineering cost and damages), and fibre optic installations expense accounts for total cost
Ratio is high.Accordingly, with respect to cable system, net configuration " three is distant " terminal is maked somebody a mere figurehead, is advantageously for input-output efficiency
's.
For interconnection switch, when its position is closer to backbone end, after by block switch isolated fault, by closing
It is then more to close the load that the interconnection switch can turn to supply.By taking more segmentation appropriateness contacts as an example, if as shown in figure 1,3 interconnection switches
In only select configuration " three is a distant " terminal, then configuration end QS9 switch when, backbone optional position failure, can pass through
After block switch isolated fault section, recover the power supply of all non-faulting sections by QF1 and QS9 closures；If configuration is in head end
QS7 switch when, QS2 to the line failure between QS9, then the non-faulting section after trouble point can not be closed by QS7
Restore electricity rapidly, it is necessary to which manually closing QS9 switches can just recover.Therefore, difficulty and appropriation budget bar are being built on an equal basis
Under part, and offside circuit turn energy supply power it is enough when, should preferentially choose the interconnection switch close to backbone end and carry out terminal cloth
Point.
To sum up, aerial net should consider Distribution Automation Construction transformation difficulty and capital budgeting situation, to interconnection switch
The distribution power automation terminal covering based on " three is distant " terminal is carried out with block switch.For interconnection switch, difficulty is built on an equal basis
Under the conditions of appropriation budget, when offside circuit turn energy supply power is enough, the interconnection switch closer to backbone end is layouted preferentially
Level is higher.
Load saturation value, which is organized, for A+ classes region, between any 2 adjacent " three is distant " nodes must not exceed 2MW." three
It is distant " node is set, and it is the main contents of A+ classes region Distribution Automation Construction；" two is distant " node can according to the actual requirements, in line with
Economical and practical principle sets (if desired primary equipment is changed, then should not be used as " two is distant " node), further reduces monitoring blind spot,
Shorten fault location time.

The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
Layouted planing method the present invention relates to a kind of distribution power automation terminal of the aerial nets of A+ regions 10kV, as shown in Fig. 2
Comprise the following steps：
1) the typical rack type and node-classification of aerial net are determined；
2) " three is distant " node is set by node-classification；
3) terminal is carried out at " three is distant " node to layout；
4) Calculation of Reliability check is powered to result of layouting；
5) optimize terminal according to check result to layout.
According to above-mentioned steps, the typical rack of the aerial nets of A+ regions 10kV is analyzed, the setting of its " three is distant " node
And the programme that terminal is layouted is as shown in table 1.
Table 1
The rack of the present embodiment comes from Shanghai Electric Power Co urban district electric company area under one's jurisdiction, belongs to A+ classes region.The region
Electricity system as shown in figure 3, being aerial backbone from loyal station from 11 outlets, sharing 1131 Zhao Zhoudongtaidong and 1044 on backbone starts
2 block switches in Zhou Hefei south, and 3 connection such as south, 0912 Hefei Ji Nanxi, 0745 Zhao Zhoujianguobei are revived by 0822 Jinan
Network switch is got in touch with other 10kV overhead lines respectively.From being stood outlet since loyalty, first backbone is segmented non-branch extension bar and become, the
Branch meets 4 bars changes and 1 user altogether for two backbone segmentations, and branch connects 4 bars changes altogether for the 3rd backbone segmentation.
According to the planing method of the present invention, 2 block switch conducts such as 1131 Zhao Zhoudongtaidong and 1044 Zhao Zhouhefeinan
" three is distant " node, 0745, which starts Zhou Jianguo north interconnection switch, is used as " three is distant " node, and south, 0912 Hefei Ji Nanxi are revived in 0822 Jinan
Deng 2 interconnection switches depending on offside line condition determine whether carry out terminal layout.Aid in " two is distant " node true by site inspection
It is fixed whether to need to add, as shown in Figure 4.
It is the aerial backbone that transformer station confesses from 11 circuits according to the planing method of the present invention, only 2 segmentations are opened
Close, therefore all as " three is distant " node.0745 to start Zhou Jianguo north interconnection switch be line end interconnection switch, therefore preferential is made
For " three is distant " node, 2 interconnection switches such as south, 0912 Hefei Jinan west are revived in 0822 Jinan to be determined depending on offside line requirements
Terminal whether is carried out to layout.If, can in addition, find that circuit has cross a river road or building etc. to make an inspection tour difficult situation by site inspection
Suitably set up auxiliary " two is distant " node.
Power supply reliability after planning is checked, the present embodiment, which is taken, calculates AFset (only consideration fault outage factors
Average power supply availability) calculate power supply reliability, design conditions are as follows：
Overhead line fault rate：0.07 times/year of .km (presses Guo Wang companies《Distribution automation planning designing technique directive/guide》Appendix B
Insulating frame ceases to be busy fault rate consider)；
ASAI3 (availability of averagely powering) desired value：99.999%；
T1 (fault zone positioning time)：1h；
T2 (by the time required to manually carrying out fault section isolation under fault location guide)：1h；
T3 (the time required to fault restoration)：4h；
Number of users：According to rack actual conditions, each bar, which becomes to become with a user, is used as an equivalent user, totally 9 etc.
Effectiveness family；
Line length：According to rack actual conditions, each section of line length has been shown on Fig. 3.
It is computed, it is 99.9985972% to make somebody a mere figurehead backbone bulk supply reliability AFset values, when not considering scheduled outage
99.999% desired value has been unable to reach, therefore " three is distant " segmentation for this circuit, should be set up in conditions permit and is opened
Close.Assuming that " three is a distant " block switch is set up, as shown in Figure 5.
Calculated again, it is 99.9991317% to make somebody a mere figurehead backbone bulk supply reliability AFset values, to reach
99.999% desired value can be that scheduled outage per family leaves 0.692min, meet Q/GDW 11184-2014《Distribution is automatic
Change planning and designing fire protection technology》Related request, thus optimize after terminal layout programme power supply reliability check pass through.
The foregoing is only a specific embodiment of the invention, but protection scope of the present invention is not limited thereto, any
Be familiar with the staff of the art the invention discloses technical scope in, various equivalent modifications can be readily occurred in or replaced
Change, these modifications or substitutions should be all included within the scope of the present invention.Therefore, protection scope of the present invention should be with power
It is required that protection domain be defined.
