Detailed description of the invention
Fig. 1 is a kind of schematic diagram of Distribution Network Failure automatic station-keeping system of the present invention.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
As shown in Figure 1, a kind of Distribution Network Failure automatic station-keeping system provided by the invention, including failure probe FD, substation ST,
Central station and master station.
In line failure, the failure probe FD on fault branch will be triggered after a failure, provide red board turning
It has been shown that, while its digitally encoded signal is sent to neighbouring by short-distance wireless transmitting unit in a manner of radio wave
Substation ST, communication distance is within 30m.The working principle of the short-circuit detecting part of failure probe FD is: according to short circuit current
Feature measures current break in route by electromagnetic induction method and the duration judges failure.Thus it is a kind of
Fault detection means related with short circuit current component when failure, criterion is more comprehensive, and can greatly reduce malfunction can
It can property.When singlephase earth fault occurs, the signal source being mounted in electric substation detects 3U0After raising, first determine whether to be out of order
Then phase mutually applies preset signals to failure, install the preset signals that this route is flowed through in failure probe FD detection on the line,
The FD starting of failure probe, provides red display, is simultaneously emitted by a wireless encoding information if meeting fault signature.Due to failure
Probe FD is a fault detection means related with short circuit current component when failure, for will not act because of underlying cause: being
Operating current increase, load switching greatly, induction-motor load greatly are put into, in system when system operating structure changes, the load becomes large
Occur in short-term excitation surge current, when artificially having a power failure after throwing big load, probe can be identified effectively and is failure to actuate, and only flow through short circuit
Electric current just provides indicating fault.
The failure teletransmission principle of aerial network
Failure probe FD is mounted on the branch line of each overhead transmission line (at branch point), and short trouble occurs in system
When, failure probe FD detects short-circuit current or preset signals electric current, and by short-distance wireless receive-transmit system, movement is believed
Number send the substation ST being separated by within 30m to.When singlephase earth fault occurs for any point on route, signal source is into route
It injects special pulse and is total to frequency signal, failure probe FD detection issues board turning when flowing through the preset signals of this route and shows, and to
Corresponding substation ST sends wireless messages.The bifurcation that substation ST is mounted on route (for longer backbone, can also suitably pacify
Fill several groups), it is at best able to receive the address that 6 failure probes FD (respectively on 6 phase lines of two branch lines) send over
Information.Substation ST pops one's head in the failure for acting branch during FD address information is sent to by short message after receiving address information
Center station.
After central station receives the information that substation ST is sent, preliminary treatment analysis is carried out, can show on the spot address information simultaneously
It saves, while giving the address information to master station in a manner of RS232.After master station obtains these address informations, into
Row network topology calculates analysis, and carry out fault location is combined with GIS-Geographic Information System, can directly display the geography that is out of order
Location information, and shown on geographical background, geographical location information can also be printed.Master station again will positioning simultaneously
Information is sent to central station, and central station is sent to the mobile phone for the related personnel being previously set in a manner of Chinese short message, this
Sample, operating maintenance personnel can directly debug to fault point according to these location informations.
The failure teletransmission principle of cable system
Fault-signal is converted into optical signal by failure probe FD, is transmitted to photoelectric converter by short distance plastic optical fiber, by
Photoelectric converter is converted into remote signalling amount and gives substation ST in switchyard, which is passed through mobile communication (GSM) again by substation ST
Net is transmitted to central station.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
