Detailed description of the invention
With specific embodiment, technical solution of the present invention is described in further detail below in conjunction with the accompanying drawings, with
Make those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not made
For limitation of the invention.
Mainly physical equipment level relation, the physical loop of the graphical representation of SPCD file.Physical layer level
Displaying relatively simple, the coherent element directly resolved in SPCD file is achieved with, the weight that this patent illustrates
Point is the methods of exhibiting of physical loop.Firstly the need of explanation, this patent is drawing physical loop process
In, will not use the mode of transformer station's full figure by the way of showing step by step, this is because: resolving inversely
Show that time space is limited owing to carrying out software interface at instrument, the most all intercept one or several physical pathway
Show；All transformer station shows in a width figure, and the autoplacement drawing to software requires high, transformer station
When scale is the biggest, the physical loop of intersection is the most, it is impossible to clearly show that physical loop figure.
Secondary system of intelligent substation physical loop file fullpath analytic method, needs the point according to interface
Hitting content real time parsing and real-time drawing function, show compared to hierarchical object, destination object no longer determines that,
The physical pathway of whole physical pathway especially fibre core needs software automatically to calculate according to SPCD file.
The physical loop resolved is needed to have three kinds by analysis: to include that the optical cable annexation shielding between cabinet resolves, shields cabinet
Between the inside fibre core annexation of optical cable resolve and jumping fiber annexation in screen cabinet resolves.
As in figure 2 it is shown, secondary system of intelligent substation physical loop file fullpath analytic method, including
Following steps:
Step 1, import SCD file and SPCD file by visualization tool；
Step 2, initialize, initialize mainly to provide for follow-up " fibre core is searched for automatically " and resolve base
Plinth, resolves and includes two contents:
(1) by resolving the empty terminal connection of SCD file, the input of each IED and the relation of output are obtained,
I.e. IED logical relation topology, the step for be equivalent to obtain forward configuration during infologic relation,
It is easy to find, through switch, the opposite side IED equipment that is associated follow-up according to side IED equipment,
The most as shown in Figure 3:
A) SCD file is imported；
B) empty terminal link information is resolved；
C) obtain the transmission of each IED and receive logical relation.
(2) by resolving the model of switch in SPCD file, the physical couplings of all switches is obtained
(i.e. the physical connection path of each port of switch), obtains switch ports themselves topology.The step for be also
For follow-up route searching servicing, when side IED equipment needs to know opposite side IED through switch
During equipment, the switch-layer topology relation that this step has been completed can help to complete route searching faster.
If switch ports themselves is direct-connected to IED device port, record this physical connection path；If switch end
Mouth is connected to light and joins machine and then enter iterative search, until searching IED device port, records this complete
Whole physical pathway；If what switch was ultimately connected to is switch, then record cascade port；More than record
Three kinds of situations, ultimately form switch ports themselves topology.
The most as shown in Figure 4:
A) traversal each port of switch；
B) physical pathway is resolved piecemeal；
If c) obtain is IED equipment, then obtains IED device end, search for next port.
If that d) obtain is ODF, then continue cycling through search, until searching out IED equipment；
If b) search is less than IED equipment, then it is assumed that is switch, then points out equipment if not switch
Type error；
C) if switch then records the port topology of switch.
Step 3, resolve: initialize after terminating, enter the formal flow process resolved, specifically include following merit
Energy module:
SPCD level resolves: traversal SPCD file, extracts respective element information, element bag according to click on content
Include transformer station, cell, screen cabinet, equipment and optical cable etc.；
SPCD physical loop resolves: according to IED logical relation topology, switch ports themselves topological sum SPCD level
Analysis result, carries out SPCD physical loop parsing, resolves including the optical cable annexation between screen cabinet, shields between cabinet
The jumping fiber annexation parsing that the inside fibre core annexation of optical cable resolves and shields in cabinet.
Introduce in detail below:
Optical cable annexation between screen cabinet: when clicking on screen cabinet, the light being associated with this screen cabinet should be able to be drawn out
Cable information, beginning and end are the screen cabinet of this optical cable, and optical cable can be to need the armored optical cable of welding can also
It it is the stern fast that need not welding.Because having special Elements C able to describe this physical connection at SPCD file
Relation, software has only to do resolve to extract and is obtained with shielding the optical cable annexation between cabinet, and this step is more
Simply, as shown in Figure 5:
Optical cable annexation between screen cabinet resolves and specifically includes following steps:
A) central display cabinet (hereinafter referred to as center screen cabinet) to be drawn can be selected by software interface；
B) traversal Cable element, obtains all optical cable information of transformer station；
C) cubicleA and the cubicleB attribute in Cable element is obtained, it is thus achieved that the both sides of all optical cables
Screen cabinet information；
D) information of filter center's screen cabinet, it is thus achieved that the screen cabinet information being connected with center screen cabinet；
E) judge whether the screen cabinet obtained in step d) has identical screen cabinet；
If f) not having, the most automatically drawing optical cable centered by the screen cabinet of Ze Yi center and connecting figure；If having, then merge
Automatically optical cable connection figure is drawn centered by the screen cabinet of screen cabinet block diagram Hou Zaiyi center.
The inside fibre core annexation of optical cable between screen cabinet: when clicking on screen cabinet, should be able to draw out screen cabinet inside and jump
Fine complete physical loop, screen fullpath within cabinet should simply shield the jumping fiber of cabinet, because in screen cabinet
Jumping fiber have partial content be on send screen cabinet between fibre core connect a part, it is contemplated that the complexity of drafting and clear journey
Degree, does not search again for fullpath.Jumping fiber in screen cabinet uses Intcore element, it is only necessary to resolve Intcore
Just can obtain jumping fiber information in cabinet.Additionally, the jumping depicted during drafting fibre core in department's screen cabinet
Fibre, draws clearly in order to more simplify, and the jumping fiber in screen cabinet is only drawn both sides and is IED equipment and entirely exists
The physical pathway of screen cabinet, as shown in Figure 6:
Jumping fiber annexation in screen cabinet resolves and specifically includes following steps:
A) connect figure interface at optical cable, select the screen cabinet of internal jumping fiber annexation to be resolved；
B) the jumping fiber IntCore element in traversal screen cabinet；
C) PortA and the PortB attribute of IntCore element is obtained, it is thus achieved that two side apparatus letters of all jumping fibers
Breath；
D) jumping fiber of IED equipment in extraction PortA and PortB is this screen cabinet.
Jumping fiber annexation in screen cabinet: when clicking on optical cable, should be able to draw out the complete of all of internal fibre core
Whole physical loop, the use of internal fibre core is extremely complex, following points specifically:
A) relate to a lot of intermediate equipment link, as one or more ODF (fibre distribution frame), one or many
Individual switch.
B) internal fibre core has the fibre core used, also either with or without the standby core used.
C) point device that rises of all fibre cores of internal fibre core is not necessarily in same screen cabinet, and end device also differs
Surely it is in same screen cabinet, causes physical loop to have length to have short, drawing layout difficulty.
D) found by IED equipment, through switch, the most easy-to-look-up next stage equipment, it is desirable to have
Corresponding algorithm supports.
E) for same optical cable, it is not necessary to be the beginning and end of equipment, may a plurality of optical cable combination
Can constitute complete physical loop, therefore there is the different position of click needs to draw the feelings in same physical loop
Condition, in other words, software needs compatible different click location to search same physical loop.
F) physical connection produces contact, but not necessarily inside has logical circuit to contact, such as route protection and intelligence
Terminal the most on switches, but both information be all by be directly connected to transmission.
For the problems referred to above, counter-measure is as follows:
A) set up fibre core automatic search algorithm, support containing ODF, the search of the physical loop of switch.
B) software drawing course considers the service condition of standby core, do not have equipment as starting point due to standby core and
Terminal, it is contemplated that make standby core at software and indicate.
C) software is drawn needs to consider location problem, supports that the equipment starting point (terminal) of same optical cable does not exists
Same screen cabinet.
D) design resolves the initialization procedure of SCD and SPC file, it is provided that the logical relation topology of IED equipment
With the port topology of switch, the follow-up lookup through switch.
E) setting up fibre core automatic search algorithm, point situation discusses the searching algorithm of different click location.
F) can not know whether current loop has service connection during drawing, the most all draw out,
" actual situation is corresponding " does not has logical circuit associated.
As it is shown in fig. 7, the inside fibre core annexation of optical cable resolves and specifically includes following steps between screen cabinet:
A) optical cable of internal fibre core annexation to be resolved is selected；
B) the Cable element of this optical cable is resolved；
C) the fibre core Core element information in Cable element is obtained；
D) fibre core Core element is resolved one by one；
E) PortA and the PortB information of Core element is obtained；
F) fibre core automatic search algorithm is called: by the fibre core Core of optical cable Cable as point of penetration, point
To both sides, i.e. A side (side being connected with PortA) and B side (side being connected with PortB) be not continuous
Extend search, finally search the IED equipment of both sides.
The physical equipment in intelligent substation secondary loop mainly includes IED equipment, ODF and switch, wherein,
The search of IED equipment and ODF is relatively simple, and the searching algorithm of switch relates to recursive call and convergence problem then
Complex, therefore " switch cyclic search is calculated in the research that focuses on of " fibre core automatic search algorithm "
Method ".According to the different optical cable positions clicked on, below point three kinds of situations are illustrated:
The first situation: as shown in Figure 8, when A side is IED equipment, fibre core automatic search algorithm is as follows:
A) search of IED equipment-ODF:
A1) B side physical pathway is resolved piecemeal；
A2) if B side is IED equipment, then obtain B side IED equipment and search terminates, under otherwise entering
One step a3)；
A3) determine whether ODF (fibre distribution frame), if ODF, then return step a1) continue to
Next section search (purpose of cyclic search is to prevent the generation of ODF transit case)；Otherwise, enter
Switch cyclic search algorithm；
B) switch cyclic search algorithm, based on " the switch ports themselves topology " analyzed when initializing and " IED
Logical relation topology ", current SWITCH can be judged:
B1) switch is determined whether, if not then reporting an error；If then entering step b2)；
B2) switch ports themselves is analyzed, it may be judged whether have switch concatenation；
B3) if it is not, then take current SWITCH port topology and A side protection measurement and control logic relationship topology common factor, obtain
All terminate after obtaining all B sides IED equipment；The most then determine whether a switch concatenation；
B4) if only one of which switch concatenation, then obtaining this switch b side IED equipment, this switch is searched
Hitch bundle, enters step b2) start the search of next switch；Otherwise enter step b5)；
B5) obtaining all B sides IED equipment of this switch, the search of this switch terminates, and simultaneously enters step
Rapid b2) the search all switches of next stage.
It should be noted that, if only one of which switch concatenation, being common cascaded switches, if there being two or more
Switch concatenation then centered by switch, general, system only one of which center switch and general with several
Logical cascaded switches cascade.Center switch, therefore this calculation typically will not be cascaded again in view of center switch
Method step b5) in, search only for an all switch of next stage and i.e. terminate.
The second situation: as it is shown in figure 9, when A side is ODF, fibre core automatic search algorithm is as follows:
01) search for A side physical pathway piecemeal, it may be judged whether be IED equipment, the most then perform when A side
For fibre core automatic search algorithm during IED equipment；Otherwise determine whether ODF；
02) if ODF is then back to step 01) continue to search for next section, otherwise judge whether it is to hand over
Change planes；
03) if not switch then reports an error, otherwise stop the search of A side and start to search for B side；
04) determine whether ODF, if otherwise optical cable connection does not meets actual conditions, otherwise, continue next section
Search；
05) judge whether it is IED equipment, the most then obtain B side IED equipment；Otherwise determine whether
ODF；
