Abstract
The invention relates to a method for preventing the misinformation of the signals of a switch device of a transformer substation in a power dispatching system, and the method solves the technical problems in the prior art that the switch device in the transformer substation always misinforms or omits in informing so that serious accidents occur, and unnecessary casualties or economic losses are caused; the following technical scheme is adopted: the method is realized based on that a monitoring circuit on a transformer substation end acquires the switch state signals of the switch device and uploads the switch state signals to a registered of a remote dispatch center to be stored; an image acquisition device for acquiring the state image information of the switch is added on the transformer substation end; and a controller with image identification management software, a special memory for storing video images and a middle memory are added in the remote dispatch center. Because the image acquisition equipment is added on the transformer substation end, the state images of the switch device are monitored in real time, detection results and the monitoring results of the monitoring circuit are compared, and the monitoring effect is enhanced.
Description
Technical field
The present invention relates to a kind of method that prevents the switching device signal wrong report of transformer station in the electric power dispatching system; Belong to fields such as electric power, oil, coal, water conservancy, railway; The circuit breaker or the disconnecting link state that are used for control centre each sub-transformer station of monitoring, particularly a kind of method based on switching device signal wrong report dual judgement, that prevent transformer station in the electric power dispatching system.
Background technology
In fields such as electric power, oil, coal, water conservancy, railway; The control centre is the maincenter of each substation; Be used for domination and manage each substation; And all need set up transformer station, transformer station to spread all over each corner in the electric power system of each substation, the contact of itself and control centre is based on network and power line transmission.Switching device in the transformer station--the on off state of circuit breaker and disconnecting link especially; By control centre's remote monitoring; Its method for supervising is in the circuit structure of circuit breaker and disconnecting link, observation circuit to be set, and this observation circuit is uploaded to the remote scheduling center in real time with the status signal of detected circuit breaker and disconnecting link.But because the influence of various interference signals; Adopt this method monitoring switching device to take place through the situation that failing to report or reporting by mistake appears in regular meeting, also serious accident can take place when serious, safest monitoring method is the state that people's naked eyes remove to observe switching device in real time; But this method is also infeasible; If in each transformer station personnel's post is set all, both waste of manpower resources can be brought certain spirit and physical and psychological pressure to the staff again.Therefore, be necessary the monitoring method of switching device in the transformer station in the prior art is improved, avoid serious accident takes place, cause unnecessary casualties or economic loss.
Summary of the invention
The present invention for reporting by mistake or failing to report often appears in switching device in the transformer station in the solution prior art thereby serious accident takes place causes the unnecessary casualties or the technical problem of economic loss; Designed a kind of method that prevents the switching device signal wrong report of transformer station in the electric power dispatching system; Through setting up image modalities at transformer station's end; State to switching device carries out image monitoring in real time, and the monitoring result of testing result and observation circuit is compared, and has strengthened monitoring effect.
The present invention for realizing the technical scheme that goal of the invention adopts is; Prevent the method for the switching device signal wrong report of transformer station in the electric power dispatching system; This method is to gather the switch state signal of switching device and be uploaded on the basis that the buffer at remote scheduling center stores at the observation circuit of transformer station end to realize; End is set up the image collection device of gathering switching device status image information in transformer station; And in remote scheduling, set up the controller that has the image recognition management software, the private memory and the intermediate store of store video images in the heart, on this basis, this method may further comprise the steps:
A, the image collection device online acquisition switching device status image information that is arranged on transformer station end, the private memory that after processed compressed, is uploaded to remote scheduling center middle controller is stored or upgrade, and controller receives switch state signal in the buffer, deposits intermediate store in simultaneously;
B, controller access the image information in the private memory, by the image recognition management software image are handled, and the state that determines switching device generates object information and is stored in the intermediate store;
C, controller carry out The matching analysis with switch state signal of storing in the above intermediate store and object information, if Signal Matching is returned steps A, proceed to keep watch on; If signal does not match, then send alarm signal.
Key of the present invention is to set up image modalities at transformer station's end, and the state to switching device carries out image monitoring in real time, and the monitoring result of testing result and observation circuit is compared, and has strengthened monitoring effect.
Image collection device and remote scheduling center among the present invention have constituted the unattended operation long distance control system, and its important function that is applied to transformer station is that equipment operation condition is monitored and managed, to carry out early warning and protection, auxiliary security production.Equipment operation operating mode telemonitoring, work on the spot behavior remote supervisory in the transformer station, the auxiliary monitoring of grid switching operation is for accident, equipment fault analysis in the field provide image and data message.Adopt advanced image coding and decoding compress technique and transmission technology; Integrate functions such as monitoring of tools, IMAQ, image monitoring forecast interlock; Make the dispatcher in control room away from the scene; Sensation on the spot in person is arranged, can be in time, accurately, analysis, failure judgement and carry out policer operation reliably.
End is installed video frequency pick-up head in transformer station; The collection site image information; Upload to Dispatch and Command Center through encoding compression technology and transmission technology, the real-time receiver, video image information of the dispatch automated system of command centre, and the comparative analysis of image is discerned before and after carrying out; Judge circuit breaker and disconnecting link state, and carry out The matching analysis through real-time circuit breaker of the transformer station of electrical system collection and disconnecting link position signalling relatively.If signal does not match, then eject the live video information frame automatically, and the voice suggestion dispatcher notices, carry out artificial treatment, thereby eliminate the real-time circuit breaker of transformer station gathered through electrical system and the error condition of disconnecting link position signalling.
Below in conjunction with accompanying drawing the present invention is elaborated.
