Methods of exhibiting.Firstly the need of explanation, this patent during drawing physical loop, by by way of showing step by step without
By the way of substation's full figure, this is because: resolving inversely due to tool carry out software interface displaying when space it is limited, one
As all intercept one or several physical pathway and show；Whole substations show in a width figure, draw to the autoplacement of software
Figure requires high, and when substation's scale is bigger, the physical loop of intersection is very more, cannot clearly show that physical loop figure.
Secondary system of intelligent substation physical loop file fullpath analytic method, needs the click on content according to interface
Real time parsing and real-time drawing function, compared to hierarchical object show, target object be no longer determining, entire physical pathway especially
It is that the physical pathway of fibre core needs software to be calculated automatically according to SPCD file.The physical loop for needing to parse by analysis has
Three kinds: being parsed including the optical cable connection relationship between screen cabinet, the inside fibre core connection relationship of optical cable parses and shields in cabinet between screen cabinet
The parsing of jumping fiber connection relationship.
As shown in Fig. 2, secondary system of intelligent substation physical loop file fullpath analytic method, including walk as follows
It is rapid:
(1) by the virtual terminator connection of parsing SCD file, the relationship of each IED output and input is obtained, i.e. IED is patrolled
Relationship topology is collected, the step is equivalent to the infologic relationship obtained in positive configuration process, convenient for passing through friendship subsequent
Associated other side IED equipment can be found when changing planes according to side IED equipment, specific as shown in Figure 3:
A) SCD file is imported；
B) virtual terminator link information is parsed；
C) obtain each IED sends and receives logical relation.
(2) by the model of interchanger in parsing SPCD file, the physical couplings for obtaining all interchangers (are exchanged
The physical connection path of each port of machine), obtain switch port topology.The step is also to take in subsequent route searching
Business, when needing to know other side IED equipment when side IED equipment passes through interchanger, interchanger that this step is completed
Topological relation can help to complete route searching faster.This is recorded if the direct-connected device port to IED of switch port
Physical connection path；Enter iterative search if switch port is connected to light with machine, is until searching IED device port
Only, this complete physical path is recorded；If what interchanger was ultimately connected to is interchanger, cascade port is recorded；Record with
Upper three kinds of situations ultimately form switch port topology.
It is specific as shown in Figure 4:
A) each port of interchanger is traversed；
B) physical pathway is parsed paragraph by paragraph；
If what is c) obtained is IED equipment, IED device end is obtained, searches for next port.
If that d) obtain is ODF, search is continued cycling through, until searching out IED equipment；
If b) search is less than IED equipment, then it is assumed that be interchanger, then prompt device type wrong if not interchanger
Accidentally；
C) port topology of interchanger is then recorded if it is interchanger.
The parsing of SPCD level: traversal SPCD file extracts respective element information according to click on content, and element includes power transformation
It stands, cell, screen cabinet, equipment and optical cable etc.；
SPCD physical loop parsing: according to IED logical relation topology, switch port topology and SPCD level parsing knot
Fruit carries out the parsing of SPCD physical loop, parses including the optical cable connection relationship between screen cabinet, the inside fibre core of optical cable connects between screen cabinet
Jumping fiber connection relationship parsing in relation decomposing and screen cabinet.
It introduces in detail below:
Shield cabinet between optical cable connection relationship: when click shield cabinet when, should be able to draw out optical cable information associated with the screen cabinet,
Beginning and end is the screen cabinet of the optical cable, and optical cable, which can be, needs the armored optical cable of welding to be also possible to not need the tail of welding
Cable.Because having special Elements C able to describe this physical couplings in SPCD file, software only needs to do parsing and extracts just
The optical cable connection relationship between screen cabinet can be obtained, this step is relatively simple, as shown in Figure 5:
Optical cable connection relationship parsing between screen cabinet specifically comprises the following steps:
A) central display cabinet to be drawn (hereinafter referred to as center screen cabinet) can be selected by software interface；
B) Cable element is traversed, all optical cable informations of substation are obtained；
C) cubicleA the and cubicleB attribute in Cable element is obtained, the two sides screen cabinet information of all optical cables is obtained；
D) information of filter center's screen cabinet obtains the screen cabinet information connecting with center screen cabinet；
E) whether the screen cabinet obtained in judgment step d) has identical screen cabinet；
It is directly automatic centered on the screen cabinet of center to draw optical cable connection figure if f) not having；If so, then merging screen cabinet block diagram
Carry out automatic drafting optical cable connection figure centered on the screen cabinet of center again afterwards.
The inside fibre core connection relationship of optical cable between screen cabinet: when clicking screen cabinet, the complete of screen cabinet inside jumping fiber should be able to be drawn out
Whole physical loop, shielding the fullpath inside cabinet should be the jumping fiber for shielding cabinet, because the jumping fiber in screen cabinet has partial content to be
On send screen cabinet between fibre core connect a part, it is contemplated that the complexity and readability of drafting do not search again for fullpath.Shield in cabinet
Jumping fiber use Intcore element, it is only necessary to jumping fiber information in cabinet can be obtained by parsing Intcore.In addition, drawing the mistake of fibre core
The jumping fiber in department's screen cabinet is depicted in journey, in order to which more simplification is clearly drawn, the jumping fiber shielded in cabinet only draws two
Side is the physical pathway of IED equipment and Quan Ping cabinet, as shown in Figure 6:
Jumping fiber connection relationship parsing in screen cabinet specifically comprises the following steps:
A) at optical cable connection figure interface, the screen cabinet of internal jumping fiber connection relationship to be resolved is selected；
B) the jumping fiber IntCore element in traversal screen cabinet；
C) PortA the and PortB attribute for obtaining IntCore element, obtains the two sides facility information of all jumping fibers；
D) jumping fiber that PortA and PortB is IED equipment in this screen cabinet is extracted.
Jumping fiber connection relationship in screen cabinet: when clicking optical cable, the complete physical of all inside fibre cores should be able to be drawn out
Circuit, internal fibre core using extremely complex, specifically following points:
A) it is related to many intermediate equipment links, such as one or more ODF (fibre distribution frame), one or more exchanges
Machine.
B) internal fibre core has the fibre core used, also either with or without the spare 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 is also not necessarily in
Same screen cabinet causes physical loop to have with short, layout of drawing difficulty.
D) it is found by IED equipment, when by interchanger, no longer easy-to-look-up next stage equipment needs corresponding calculation
Method support.
E) for the same optical cable, it is not necessarily the beginning and end of equipment, possible a plurality of optical cable combination could be constituted
Complete physical loop, therefore exist and click the case where different positions needs to draw same physical circuit, in other words, software
It needs to be compatible with different click locations and searches same physical circuit.
F) physical connection generates connection, but it is not necessarily internal have logical circuit connection, all such as route protection and intelligent terminal
On switches, but the information of the two is all by being directly connected to transmit.
In view of the above-mentioned problems, counter-measure is as follows:
A) fibre core automatic search algorithm is established, supports the search to the physical loop containing ODF, interchanger.
B) software drawing course considers the service condition of spare core, since spare core does not have equipment as beginning and end,
It is contemplated that doing spare core mark in software.
C) software draws and needs to consider location problem, supports the equipment starting point (terminal) of the same optical cable not in same screen
Cabinet.
D) initialization procedure of design parsing SCD and SPC file provides the logical relation topology and interchanger of IED equipment
Port topology, the convenient subsequent lookup by interchanger.
E) fibre core automatic search algorithm is established, point situation discusses the searching algorithm of different click locations.
F) it can not know whether current loop has service connection during drawing, still all draw out, " actual situation
It is corresponding " it is associated without logical circuit.
As shown in fig. 7, the inside fibre core connection relationship parsing of optical cable specifically comprises the following steps: between screen cabinet
A) optical cable of internal fibre core connection relationship to be resolved is selected；
B) the Cable element of the optical cable is parsed；
C) the fibre core Core element information in Cable element is obtained；
D) fibre core Core element is parsed one by one；
E) PortA the and PortB information of Core element is obtained；
F) it calls fibre core automatic search algorithm: by the fibre core Core of optical cable Cable as point of penetration, being to two sides respectively
The side A (side being connected with PortA) and the side B (side being connected with PortB) constantly extend search, finally search two sides
IED equipment.
The physical equipment in intelligent substation secondary circuit mainly includes IED equipment, ODF and interchanger, wherein IED equipment
Relatively simple with the search of ODF, the searching algorithm of interchanger is related to recursive call and convergence problem is then complex, therefore " fine
Core automatic search algorithm " focuses on research " interchanger cyclic search algorithm ".According to the different optical cable positions of click, below
Point three kinds of situations are illustrated:
The first situation: as shown in figure 8, when the side A is IED equipment, fibre core automatic search algorithm is as follows:
A) search of IED equipment-ODF:
A1 the side B physical pathway) is parsed paragraph by paragraph；
A2 it) if the side B is IED equipment, obtains the side B IED equipment and search terminates, otherwise enter next step a3)；
A3) judge whether it is ODF (fibre distribution frame), if it is ODF, then return step a1) continue to search for next section
(purpose of cyclic search is to prevent the generation of ODF transit case)；Otherwise, into interchanger cyclic search algorithm；
B) interchanger cyclic search algorithm, " the switch port topology " analyzed when based on initialization and " IED logical relation
Topology ", can judge current SWITCH:
B1 interchanger) is judged whether it is, if not then reporting an error；If then entering step b2)；
B2) switch port is analyzed, judges whether there is switch concatenation；
B3) if it is not, current SWITCH port topology and the side A is then taken to protect the intersection of measurement and control logic relationship topology, all B are obtained
All terminate after the IED equipment of side；If so, judging whether there is a switch concatenation；
B4) if only one switch concatenation, this switch b side IED equipment is obtained, the search of this interchanger terminates, into
Enter step b2) start next interchanger search；Otherwise b5 is entered step)；
B5 all side B IED equipment of this interchanger) are obtained, the search of this interchanger terminates, while entering step b2) search
All interchangers of next stage.
It should be noted that being common cascaded switches if only one switch concatenation, if there are two the above interchangers
Cascade is then center interchanger, in general, only one center switch of system and with several common cascade switch concatenations.
In view of center switch will not generally cascade center switch, therefore this algorithm steps b5 again) in, search only for a next stage
All interchangers terminate.
Second situation: as shown in figure 9, when the side A is ODF, fibre core automatic search algorithm is as follows:
01) side A physical pathway is searched for paragraph by paragraph, judges whether to be IED equipment, if so, executing when the side A is IED equipment
Fibre core automatic search algorithm；Otherwise judge whether it is ODF；
02) it is then back to step 01) if it is ODF to continue to search for next section, otherwise judges whether it is interchanger；
03) if not interchanger then reports an error, otherwise stop the search of the side A and start to search for the side B；
04) judge whether it is ODF, if otherwise optical cable connection does not meet actual conditions, otherwise, continue next section of search；
05) judge whether to be IED equipment, if so, obtaining the side B IED equipment；Otherwise judge whether it is ODF；
Wherein, if IED equipment, then after obtaining the side B IED equipment, it may also begin to the search side Port A, since the side A is searched
Rope stops at interchanger, then calls " interchanger cyclic search algorithm " can obtain the side A IED by the input side B IED equipment and set
It is standby.
If 06) ODF, then continues next section and search for and enter step 05)；If not ODF, then judge whether to be exchange
Machine；
07) if not interchanger then reports an error, otherwise judge that this fibre core to cascade fibre core, can not draw and terminate.
The third situation: as shown in Figure 10, when the side A is interchanger, fibre core automatic search algorithm is as follows:
001) stop the search of the side A, start the search of the side Port B, parse paragraph by paragraph；
