Description
Technical field
The present invention relates to the electric power system in distribution network automated, especially can judge abort situation more accurately, the more convenient distribution network automated implementation method of rural power grids circuit, single supply circuit israds road being protected isolation.
Background technology
Along with distribution network automated enforcement; Increasing distribution network automated scheme has been arranged now; Can realize the operation monitoring of power distribution network and the automated system of control, possess that distribution SCADA (supervisory control and data acquisition), feeder automation, electrical network analysis use and with function such as related application system interconnection.Existing distribution network automated implementation method also all is three kinds of patterns at traditional main website+substation (optional)+terminal, though this pattern can realize distribution network automated function, because the terminal equipment price is more expensive comparatively speaking; Be not adapted at all installing between each switch or the line bar, but select occasions such as important switch or ring main unit, switching station to install, like this; The faulty line that the power distribution network terminal indicates will be long, and scope is bigger, and according to statistics; In the circuit fault handling process; Confirm that abort situation is the most time-consuming, approximately can account for 2/3rds of fault handling time, therefore; Can not judge abort situation accurately, just be unfavorable for that the failure judgement position is so that handle rapidly.And if radiativity circuits such as branch line are arranged within this scope, and the fault point is on the branch line, can cause basic routing line to be isolated, and enlarged the power failure scope.
Summary of the invention
The object of the invention is exactly in order to solve the deficiency of existing distribution network automated power system technology; A kind of distribution network automated implementation method is provided; Through this method, be the distribution network automated fault location accurately that provides, excessive to solve in traditional distribution automation system the fault location scope; Need the cost plenty of time to confirm abort situation, and faults such as rural power grids circuit, single supply circuit are expanded to the problem that processing produced of basic routing line.
The technical solution adopted for the present invention to solve the technical problems is: a kind of distribution network automated implementation method, form by the extension and the perfect of distribution network automated data of distribution automation system body and power distribution network information.The body of distribution automation comprises three-decker: ground floor is the distribution automation management system, comprises SCADA/EMS, GIS, DAS etc.; The second layer is the distribution substation, management area distribution network terminal, FA; The 3rd layer is feed line automatization terminal FTU, DTU, TT, the high reliability of complete, the high accuracy of these three layers of adjusting datas eager to excel in whatever one does, high reliability and communication; Under the power distribution network terminal, insert a distant point device; Realize the extension of distribution information; Distribution data perfect like automatic circuit circuit, fault detector, can accurately be indicated the position of the feeder line that breaks down; And with sending main website on this information, so that the quick failure judgement of power supply department position, fast processing fault; With traditional distribution main website, distribution substation, distribution network terminal three layer models, make " distribution main website, distribution substation, distribution network terminal, distant point four layer models into; The data of 1 distant point are collected in the close power distribution network terminal through communication; Through communicating by letter of terminal and substation or main website with delivering to main website on the data; Thereby get final product accurate failure judgement position in main website, protection is moved, isolated fault is regional and non-fault zone restores electricity conveniently to implement; Because a distant point device price is relatively cheap, deployment that can be more, and can be deployed on the radial line; The accurate position of judging the fault point, when basic routing line breaks down, with localization of fault between two line bars; And when branch line, when break down in rural power grids circuit israds road; Can the switch of basic routing line and branched line be broken off, thereby realize Fault Isolation, obviously reduce the outage scope.
The invention has the beneficial effects as follows that distribution network automated implementation method can be judged abort situation accurately, minimum can be positioned abort situation between the line bar; One distant point device price is relatively cheap; Can accomplish the accurate location of fault and to the optimization process of radial line; Can price be controlled within the reasonable range again; It is convenient to transform, and easily a distant point device is linked in the distribution network automated terminal after installing distribution network automated terminal additional, transforms to accomplish.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
Fig. 1 is the logical framework figure of traditional distribution pattern.
Fig. 2 is an overall logic frame diagram of the present invention.
Fig. 3 is a network topological diagram of the present invention.
Embodiment
Shown in Fig. 1, owing to do not have other equipment between two station terminals, can only be between two station terminals with localization of fault, fault location is quite fuzzy.
Shown in Fig. 2 embodiment, during line failure, the power distribution network terminal can judge whether feeder line has fault according to the information that collects, and can receive the fault message from a distant point device simultaneously; The terminal uploads to the substation with fault message of self judging and the fault message of receiving from a distant point, and the substation can be received these fault messages and is forwarded to main website; Main website receives the fault message that the terminal of coming is transmitted in the substation, carries out fault location according to these fault messages, can navigate to very easily between two station terminals, and produce protection, isolation action; Simultaneously main website is also according to the fault message of a distant point device; Fault location between two one distant point devices, has been dwindled the scope of fault location, and abort situation has been shown on generalized information system; So that the primary fault processing procedure has so just been accomplished in maintenance.
Shown in Fig. 3 embodiment, 4 kinds of equipment are arranged, a distant point device quantity is maximum, and price is relatively cheap, and the information gathering amount is little, but scope is accurate; Terminal equipment quantity is more, and the information gathering amount is big, but judges the scope inaccuracy; Substation (optional) equipment is mainly used in communication, can the data preparation that send up at the terminal be uploaded to main website; Main website equipment is used for the data that send up at substation or terminal are put in order, preserved and show.
