Abstract
The invention provides a line failure indication control method based on PI (plant information) real-time database, comprising the following steps: firstly, acquiring the data of a load current, an earth current, an electric field to the earth and a short-circuit current of an operational circuit by virtue of a line failure data acquisition module, and then checking the data and converting the format of the data; secondly, storing the data acquired in the step one into a PI database processing module; and thirdly, extracting the data in the PI database processing module by virtue of a data operation analysis module and analyzing the data. By applying the method in the invention, the operational state of a line can be timely known, the timely prevention can be realized, a hidden trouble can be eliminated in advance, and the timely and accurate location can be realized after a fault occurs.
Description
Technical field
The present invention relates to line fault indication control method based on the PI real-time data base.
Background technology
China 10KV city and rural power distribution rack ceases to be busy road failure ratio are more, and traditional troubleshooting mode does not realize the failure message upload function, in case circuit breaks down, need manually to search along the line, have still increased troubleshooting difficulty and time.And utilize distribution automation system can realize the automatic location of fault, but cost is too big, is difficult to promote.Therefore, utilize means of communication simple, with low cost that failure message is uploaded to system of robotization main website, thereby the automatic location of realizing fault section is very necessary.In recent years along with some line fault indication mechanisms are developed in the development whole nation of mechanics of communication and automatic technology in succession, but these systems can only accomplish to determine abort situation for the maintainer according to this system behind the line failure, dwindle the investigation scope.Can't accomplish early warning.
Summary of the invention
Technical matters to be solved by this invention is to provide the line fault indication control method based on the PI real-time data base, can in time understand the operation conditions of circuit, accomplish timely prevention, get rid of hidden danger in advance, and location that also can be promptly and accurately after breaking down.
For solving above-mentioned existing technical matters, the present invention adopts following scheme: the line fault indication control method based on the PI real-time data base may further comprise the steps:
Step 1: the load current by line fault data collecting module collected working line, ground current, to earth electric field, the every data of short-circuit current, then data are proofreaded and format conversion;
Step 2: the every data that obtain in the step 1 are saved in the PI database processing module;
Step 3:, and analyze by the every data in the data run analysis module extraction PI database processing module.
As preferably, be with the load current of working line, ground current, in the line fault data acquisition module in the described step 1 by Ethernet to earth electric field, the every data acquisition of short-circuit current, and adopting the verification mode of CRC 16 that every data are proofreaded, the every data that will gather are then carried out format conversion.
As preferably, described line fault data acquisition module is linked into every data in the PI database processing module by PI database interface software, and every data that PI database processing module will insert are saved in corresponding data cell.
As preferably, described data run analysis module comes out the data extract in the PI database processing module, and the prevention alarm is in time accomplished in every data analysis data variation of real-time follow-up circuit, phase bit comparison, accurate location after the fault.
Beneficial effect:
The present invention adopts technique scheme that line fault indication control method based on the PI real-time data base is provided, and can in time understand the operation conditions of circuit, accomplishes timely prevention, gets rid of hidden danger in advance, and location that also can be promptly and accurately after breaking down.
