Description
Technical field
The utility model relates to power distribution automation field, particularly a kind of OO distribution network system.
Background technology
Electrical power distribution automatization system has certain scale and carries out in China and experiences recent two decades.
From the later stage nineties in last century, along with the develop rapidly of computer information technology and mechanics of communication, electrical power distribution automatization system starts to carry out in various places pilot.Main Patterns is:
Each Utilities Electric Co. sets up DSCADA system for low-voltage network;
Select emphasis rack good, protect electric region distribution terminal be installed;
Adopt the special line communication medias such as carrier wave, microwave, optical fiber, by distribution terminal, on-load switch, circuit operation real time data are reported to DSCADA on the spot.
Do not carry out the region of Long-distance Control and realize remote signalling, the distant function of remote measurement two; Except two distant real-time monitoring, in the time of fault, be there is to the real time data in moment according to fault by the dispatcher of main website in the distribution region that can far control, carry out artificial judgment, send guidance command excision faulty section.
The thought of this regional distribution network is that the extension of centering high voltage substation complex automatic system is used.But through practice for many years, find some problems, be mainly:
1, the power distribution network scale of construction is huge, and current region pilot coverage rate is very limited, and scattered, isolated island data that DSCADA can only obtain, so the inreal practical running of DSCADA.
2, due to construction and the investment limitation of communication network, data are delivered to automation of transformation substations telemechanical apparatus nearby by general distribution terminal, passes on main website by transformer station's telemechanical as data concentrator.Make the debugging complexity of system, communication protocol, communication form are varied.
3, the regular topology that needs of power distribution network changes, and in the region of having implemented power distribution automation, the variation of topology needs very complicated loaded down with trivial details configuration debugging work.
These problems finally all make the practicality of current electrical power distribution automatization system greatly reduce.
Referring to Fig. 1 and Fig. 2, this is current traditional area power distribution network networking communication form, and power distribution automation regional network extends the integrated automation of transformation stations pattern that adopts more.Data are taking terminal harvester as a minimum substation, and all online terminals separately data are sent to region communication concentrator, and full-time concentrator is directly sent to DSCADA, also has the part-time concentrator transfer of remote station to pass to DSCADA.
For indirect transfer mode, because the automation equipment of each transfer website is for different producers, its communications protocol adopting is different, even identical agreement, in realization, also have very big-difference, debugging a terminal needs distribution terminal producer, transfer automation producer, DSCADA tripartite to coordinate, and makes to debug work relative complex difficulty.
For direct access way, and adopt CDT or IEC870-5-101 directly to access DSCADA, need a large amount of access passages.
No matter be which kind of networking communication form, data all adopt the conventional communications protocol in telemechanical field to transmit.These communications protocol comprise circulation stipulations CDT promulgated by the ministries or commissions of the Central Government, Polling Protocol IEC870-5-101 etc.
Data, by remote signalling (switching value input), remote measurement (analog input), remote control (output of switch controlled quentity controlled variable) classification, are arranged all kinds of data points by period.Data are just organized into remote signalling the 1st point～the N point like this; Remote measurement the 1st point～the N point; Remote control the 1st point～the N point.
With the communication of main website, exactly by CDT, IEC870-5-101 by the data of these types by type framing send to the side of needs.
What actual amount point in the actual expression of data electric power system, is to be completed by the agreement of communication two party, and this agreement is a table, and type is as following table, and it is circuit one A phase overcurrent that both sides arrange the 40th of remote signalling, and the 41st is circuit one B phase overcurrent ...
Visible, when after the variation of distribution topology, the data point of transmission may increase and decrease to some extent, arranges also possibility change, makes each topology of changing all should again test the point that check and correction changes.This is difficult to organize and coordinate to the station of putting into operation the work of variation.
