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 based on maintenance work station, especially relate to a kind of by the detection method of the feeder automation in-circuit emulation method based on maintenance work station.
Background technology
Distribution network systems generally by being arranged on the main station system at distribution scheduling center, the remote control terminal (FTU) that is arranged on the substation system of Substation control chamber and is arranged on each distribution network terminal (as on-pole switch) forms.Main station system is connected by bidirectional line with substation system; Substation system is also connected by bidirectional line with FTU.
Wherein, FTU carries out the monitoring of current/voltage, on off state, differentiation, record and reporting fault information, and carry out the network reconfiguration order that the fault handling order of sending substation and main website send; Substation system can forward FTU by the information of main website on the one hand, the information of FTU is forwarded to main website simultaneously, processes on the other hand the failure message that corresponding FTU reports, and failure judgement region also issues isolated instructions; The fault isolation information that main station system reports substation system is carried out discriminatory analysis, realizes the recovery of non-fault zone.
Above-mentioned flow process is called feeder automation, realizes fault isolation and network reconfiguration in distribution automation system: in the time of distribution line or device fails, by FTU by fault information reporting substation system, by substation system to localization of fault and carry out zonal isolation; When fault zone exceeds this substation system institute's compass of competency or isolates unsuccessfully, substation system reporting fault information, to main station system, is coordinated each substation system by main website, implements automatic fault isolation; After having isolated, main station system is according to the fault of substation system and isolation information, start damage assessment routine (DAR), analyze real-time telemetry, the remote signalling of network, according to power network topology result, select best non-fault zone to recover, and by Remote Control Automatic reconstructed network, the non-fault zone power supply of fast quick-recovery, to dwindle power failure range, reduces power off time.
For above-mentioned feed line automatization system, carry out fail-test to its function, never relatively ripe 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 laboratory is built network, test, after to be tested completing, carry out again on-the-spot installation and operation, but test in laboratory, involve the each side factors such as field channels due to feeder automation, the actual conditions that result can not complete reaction scene are tested in its test, and such detection method does not meet relevant rules, the regulation of electric system yet simultaneously; Second method is in the time of feed line automatization system final acceptance of construction; distribution line is carried out to real mould test; by synchronously simulating physical fault on transformer station's outlet protection and terminal device; whole feed line automatization system is verified; but each several part cooperating when its test preliminary work and test is very loaded down with trivial details; its setup time is very long; involve a large amount of human and material resources; and synchronous fault is difficult to accurate assurance; therefore cannot put into operation handing-over operation and daily verification as distribution automation system time, the universal method that feeder automation function is tested.
Summary of the invention
The object of this invention is to provide a kind of in-circuit emulation method of feeder automation, the method can be carried out fault simulation and test completely to feeder automation function under the condition of not impact equipment operation, and guarantee that this testing process is convenient, consuming time short, cost is low.
For foregoing invention object, we provide a kind of feeder automation in-circuit emulation method based on maintenance work station, comprise the following steps:
A. predetermined system wiring diagram on the emulation simulator at maintenance work station, and there is rear action in relative clock, trouble duration, fault that trouble spot, fault are occurred, primary equipment (switch) locking information is made an appointment;
B. the information in step a is converted into script file;
C. the script file generating in step b is issued to each remote control terminal by substation;
D. substation receives the distant signal of remote control terminal, confirms that script file successfully enters remote control terminal;
E. send fill order by substation, start the script file operation of remote control terminal;
F. remote control terminal simulation output failure message, and failure message is fed back to substation;
G. substation receives fault-signal, makes abort situation judgement, or failure message is upwards fed back to main website;
H. the fault handling information that main website makes, or the fault handling information going down that substation is directly made is to remote control terminal;
I. remote control terminal performs an action, and result is uploaded;
J. exit in-circuit emulation.
Improve as one, in described step I, when remote control terminal performs an action, primary equipment (switch) can locking also can not locking, if primary equipment (switch) locking, execution result is to be produced by remote control terminal simulation so; If not locking of primary equipment (switch), execution result is primary equipment (switch) the result of the action so.
Adopt after above-mentioned technological means, its beneficial effect is apparent, and we know that a feed line automatization system can be divided into two parts, a part be failure message seizure, confirmation; Another part is the transmission of failure message and the location of fault zone, isolation, recovery.Feeder automation function has all been carried out strict test by protection tester in the time of product export, is guaranteed in reliability aspect fault seizure; In actual field, the failed major part of feeder automation test is to cause because field channels is abnormal, parameter configuration is improper etc.Feeder automation in-circuit emulation method provided by the present invention is based on maintenance work station, and its whole analog simulation process is based on various physical devices, so the various situations in can complete reaction reality.Meanwhile, because the setting of various faults in simulation process is all preset on network, so the emulation start-up and operation of fault does not need to expend a large amount of man power and materials, and the emulation degree of accuracy of fault is high, large to actual feed line automatization system directiveness.
In a word, the in-circuit emulation detection method based on maintenance work station provided by the present invention not only simple to operate, consuming time short, cost is low, and does not affect the normal operation of each equipment in network.
