Description
Technical field
The present invention relates to distribution technique field, relate in particular to the automatic method for refreshing of a kind of feeder line scope.
Background technology
In distribution network planning modeling process, conventionally planning personnel can create transformer station as required, the transformer station from newly-built or present situation electrical network sets up new line.Newly-built circuit prolongs cloth to load by certain trend, can create many branch lines simultaneously, to a plurality of load power supplies, likely can create in addition interconnection and be connected with other feeder lines.On interconnection, conventionally can create interconnection switch, the service area of two feeder lines of user isolation also may create a plurality of block switches on same feeder line., just there are different purposes in not essential distinction between block switch and interconnection switch in physical network in application, and block switch normal condition is closed, and interconnection switch normal condition plays buffer action for opening.And in planning, revise the folding condition of switch, also just mean that their character is to switch between block switch and interconnection switch.Therefore, feeder line scope can change according to the state of switch is different.In distribution planning modeling program, also just need according to the equipment state in network, automatically to determine the affiliated relation between feeder line scope and feeder line trunk and branch.This relation can be used for carrying out planning management and statistics, and the senior application such as automatic generation of electrical network line chart, system diagram.
Comprise at present in the distribution modeling process of planning, generally have two kinds of modes to process the problem of relation between feeder line scope and feeder line.1, adopt artificial mode of specifying feeder line scope, by hand the border of every feeder line delimited, indicate which switch is block switch, which is interconnection switch, by interconnection switch, divides feeder line service area.Common method of operating is, during conducting transmission line planning modeling, first to determine the backbone of circuit, the manual parent branch of determining this branch during by backbone branch, by that analogy, until final stage branch determines that this switch is interconnection switch or block switch when line end creates switch; While carrying out circuit reconfiguration, which bar circuit the new parent branch of the branch of manual confirmation reconfiguration is, what direction the direction of current under normal condition is.2, feeder line scope is not divided, only carry out basic topological relation management, in this model, there is no feeder line concept.
Based on upper type 1, due to need to be in modeling editor's process relation and branch's relation under clear and definite feeder line middle conductor, planning personnel is had relatively high expectations, because itself just there are a lot of uncertainties of circuit in planning business, so be difficult to determine these information in planning process; Because the data volume of needs input is larger, easily cause mistake in addition, cause branch to be related to mistake; In the process of revising on off state, the often change of attribute due to block switch and interconnection switch, causes the variation of feeder line scope, also needs to carry out branch and is related to modification, easily ignores operation wherein in operation, causes error in data.Based on mode 2, owing to there is no feeder line scope and branch's relation, this way to manage is different from normal distribution network way to manage, being necessary it is to name for feeder branch, cannot carry out branch management.Can cause automatically generating the functional characteristics such as line chart cannot use.
Summary of the invention
The object of this invention is to provide the automatic method for refreshing of a kind of feeder line scope, the deficiency existing to overcome currently available technology.
The object of the invention is to be achieved through the following technical solutions:
The automatic method for refreshing of feeder line scope, comprises the following steps:
1) find all transformer stations, from transformer station's outlet, by topological order, travel through downstream the equipment of current feeder line successively, the parent branch of current branch is set for empty, record the affiliated branch (A) of the current equipment traversing and feeder line (F);
2) equipment travels through with this downstream, if branch is not empty and identical with parent branch under equipment, under first arranging, branches into sky;
3) if this equipment of judgement under branch into sky, create new branch (B) as branch under current device, and current device feeder line attribute is set is current feeder line (F), and the parent branch (A) of current branch (B) is set;
4) continue, to next equipment traversal, to judge the follow-up branch that whether has;
5) if follow-up equipment is more than one, check successively the affiliated branch of follow-up equipment, if the identical continuation of You Yuben branch circulates to this device orientation, other branch (C) enters recurrence; And
6) equipment that enters circulation continues step 2).
Further, in step 5), the parameter that enters the equipment of recurrence is current branch (B), as the father branch in recursive function, records the affiliated branch (A) of the current equipment traversing and feeder line (F).
Further, in step 5), run into closed Switch equipment, the line segment that switch both sides connect all as follow-up equipment, if still there is Switch equipment in follow-up equipment, carries out recursive detection and collects all follow-up equipments except current device.
Further, in step 5), encounter Closing Switch kind equipment, first the affiliated branch line of detector switch, if current branch does not change, otherwise another port of detector switch, if only have an equipment, the equipment as branch under the other end switch; If there is bifurcated (having connected two or more equipment) switch another port, switch is processed as this branch equipment; If this switch directly connects other switches, need to continue to enter the checking that recurrence is carried out switch.
Further, in step 5), there is no follow-up equipment, circulation finishes.
Further, in step 5), run into load kind equipment, load equipment direction does not enter circulation.
Further, in step 5), run into transformer station's circulation and finish.
Further, in step 5), run into the equipment traveling through, to this device orientation, do not enter circulation.
Beneficial effect of the present invention is: the method is by automatic mode, determine the affiliated and hierarchical relationship between circuit top set, be conducive to the management to branch's relation, this way to manage of circuit more approached to power circuit actual operating, be conducive to user to the understanding of circuit and maintenance; Reduce user modeling workload, improved the accuracy of data maintenance, improved system availability; It is line management situation that data after refreshing are more close to the users actual, improves the maintainability of data.
