Abstract
The invention relates to a distribution network system detecting method, particularly to a distribution network system detecting method based on a maintenance workstation, and particularly to a feeder automation online simulation method based on the maintenance workstation. As for the automation online simulation method based on the maintenance workstation, the whole simulation process is operated in actual devices; and the faults are preset in a network. The method has the advantages of simplicity in operation, short consumed time and low cost, and does not influence normal operation of devices in the network, and meanwhile, the fault accuracy rate is high, thus the method is significant to the actual feeder automation system monitoring.
Description
Technical field
The present invention relates to a kind of distribution network systems detection method, particularly relate to a kind of distribution network systems detection method, especially relate to a kind of detection method of passing through based on the feeder automation in-circuit emulation method at maintenance work station based on the maintenance work station.
Background technology
Distribution network systems generally is made up of the main station system that is installed in the distribution scheduling center, the remote control terminal (FTU) that is installed in the substation system of transformer station pulpit and is installed in each distribution network terminal (like on-pole switch).Main station system is connected through bidirectional line with substation system; Substation system also is connected through bidirectional line with FTU.
Wherein, FTU carries out the monitoring of current/voltage, on off state, differentiates, writes down and report failure message, and carry out fault handling order of sending the substation and the network reconfiguration that main website sends and order; Substation system can be transmitted FTU with the information of main website on the one hand, simultaneously the information of FTU is transmitted main website, handles the failure message that corresponding FTU reports on the other hand, and the failure judgement zone also issues isolated instructions; Main station system carries out discriminatory analysis to the fault isolation information that substation system reports, and realizes the recovery of non-fault zone.
Above-mentioned flow process is called feeder automation, realizes fault isolation and network reconfiguration in the distribution automation system: when distribution line or device fails, by FTU with the fault information reporting substation system, by substation system to localization of fault and carry out zonal isolation; When the fault zone exceeds this substation system institute's compass of competency or isolates unsuccessfully, substation system reports failure message to give main station system, coordinates each substation system by main website, implements automatic fault and isolates; After isolating completion, main station system starts damage assessment routine (DAR) according to the fault and the isolation information of substation system; The real-time telemetry of phase-split network, remote signalling according to the power network topology result, select best non-fault zone to recover; And through Remote Control Automatic reconstructed network; The non-fault zone power supply of fast quick-recovery to dwindle the power failure scope, reduces power off time.
For above-mentioned feed line automatization system, carry out fail-test to its function, never ripe relatively solution.Present stage mainly contains two kinds of methods: a kind of method is before feed line automatization system is installed at the scene; Actual state according to distribution in the laboratory is built network, makes an experiment, and treats to carry out on-the-spot installation and operation again after test is accomplished; But make an experiment in the laboratory; Because feeder automation involves each side factors such as field channels, the result is tested in its test can not the on-the-spot actual conditions of complete reaction, and such detection method does not meet relevant rules, the regulation of electric system yet simultaneously; Second method is when the feed line automatization system final acceptance of construction; Distribution line is carried out real mould test, promptly, come whole feed line automatization system is verified through synchronously simulating physical fault on transformer station's outlet protection and terminal device; But the each several part cooperating when its test preliminary work and test is very loaded down with trivial details; Its setup time is very long, involves a large amount of human and material resources, and fault is difficult to accurate assurance synchronously; Therefore in the time of can't putting into operation handing-over operation and daily verification as distribution automation system, the universal method that the feeder automation function is made an experiment.
Summary of the invention
The in-circuit emulation method that the purpose of this invention is to provide a kind of feeder automation; This method can be carried out fault simulation and test completely to the feeder automation function under the condition that does not influence equipment operation; And guarantee that this testing process is convenient, weak point consuming time, cost is low.
To the foregoing invention purpose, we provide a kind of feeder automation in-circuit emulation method based on the maintenance work station, may further comprise the steps:
A. predetermined system wiring diagram on the emulation simulator at maintenance work station, and to relative clock, trouble duration, the fault that trouble spot, fault take place the back action takes place, primary equipment (switch) locking information is made an appointment;
B. the information among the step a is converted into script file;
C. the script file that generates among the step b is issued to each remote control terminal by the substation;
D. the substation receives the distant signal of remote control terminal, confirms that script file successfully gets into remote control terminal;
E. send fill order by the substation, start the script file operation of remote control terminal;
F. failure message is exported in the remote control terminal simulation, and failure message is fed back to the substation;
G. the substation receives fault-signal, makes abort situation and judges, or failure message is upwards fed back to main website;
H. the fault handling information made of main website, or the fault handling information that the substation is directly made is passed to remote control terminal downwards;
I. remote control terminal is carried out action, and result is uploaded;
J. withdraw from in-circuit emulation.
As a kind of improvement, in the said step I, when remote control terminal is carried out action, primary equipment (switch) can locking also can not locking, if primary equipment (switch) locking, execution result is to be produced by the remote control terminal simulation so; If not locking of primary equipment (switch), execution result is primary equipment (switch) the result of the action so.
After adopting above-mentioned technological means, its beneficial effect is conspicuous, and we know that a feed line automatization system can be divided into two parts, a part be fault information seizure, affirmation; Another part is location, isolation, the recovery of fault transmission of Information and fault zone.The feeder automation function has all been carried out strict test through the protection tester when product export, be guaranteed in reliability aspect the fault seizure; In actual field, the failure major part of feeder automation test is because field channels is unusual, parameter configuration is improper etc. causes.Feeder automation in-circuit emulation method provided by the present invention is based on the maintenance work station, and its whole analog simulation process is based on various physical devices, so the various situation in can complete reaction reality.Simultaneously, because the setting of various faults all is preset on the network in the simulation process, so the emulation of fault startup and operation do not need the man power and material of labor, and the emulation degree of accuracy of fault is high, and is big to the feed line automatization system directiveness of reality.
In a word, the in-circuit emulation detection method based on the maintenance work station provided by the present invention weak point not only simple to operate, consuming time, cost are low, and do not influence the normal operation of each equipment in the network.
