Digital display method of printed information of relay protection device

Abstract

The invention relates to a digital display method for print information of a relay protection device, belonging to the technical field of digital processing of power data. The method is executed according to the following steps of: 1) monitoring a print interface of the relay protection device by a print data acquisition module arranged in a substation in real time; 2) performing pre-analysis and analysis of print data transmitted to a backstage host; 3) storing the print data, saving the print data in a database, and classifying according to a time initiated by a print task and summary information of the print task; and 4) synchronizing the print data to a master station from the substation through a network, wherein the print data comprises configuration information of the substation, a setting value of the relay protection device and print task information. By the method, remote monitoring on the print information of the relay protection device is achieved so as to make the print information digital.

Description

technical field [0001] The invention relates to a digital display method for printing information of a relay protection device, and belongs to the technical field of electric power data digital processing. Background technique [0002] When the power components (such as generators, lines, etc.) An automated measure and device in which a circuit breaker issues a trip command to terminate the development of these events. At the same time, the printer connected to it will print the situation data on the spot for reference by relevant personnel. Relevant personnel who arrive at the scene record the problem on the information record sheet or other registers. [0003] Sometimes, there is no real abnormal situation on site, but false alarms caused by the interference of other factors in the working environment of the relay protection device, including electromagnetic, vibration, current, temperature, humidity, air, man-made, etc. . Since the ground survey cannot obtain protecti...

Problems solved by technology

However, the method of obtaining the fault event report printed by the relay protection device is still to drive to the substation site for printing, which is time-consuming, laborious, and inefficient, and it is impossible to know the relevant situation of the accident in the first place, and can only be indirectly learned through dispatching or credit systems. Unable to recover from the accident in the first time

[0004] As for the protective screen cabinet equipped with a printer, due to the low incidence of accidents, long-term non-use will lead to printer ribbon aging, dust pollution, paper jams and lack of paper, etc., the printer needs to be maintained regularly, which is very important for the power system. a very large expense

[0005] For the protection screen cabinet without printer (due to the regulations of the State Grid Electric Power Co., Ltd. on the protection screen cabinet, the protection screen cabinet is not connected to AC power, and the relay protection equipment is not equipped with a printer), in this case, personnel are required to go to the site for temporary installation printer, and the introduction of alternating current, the same style is a cumbersome operation

[0006] After obtaining and analyzing the failure event report printed by the relay protection device, it is necessary to archive the handling process of the accident. At present, the power bureau requires two ways of archiving, one is paper file archiving, and the other is electronic Format archive, because the printed content cannot be digitized, it can only be scanned into pictures for archiving, and because the printed paper documents are continuous sheets of printing paper instead of A4 paper, the scanning work is more cumbersome
