Network printing system of relay protection device

Abstract

The present invention relates to a networked printing system of a relay protection apparatus and belongs to the technical field of power data digital processing. The system comprises a substation subsystem and a primary station subsystem; The substation subsystem comprises a printing data acquisition module, a first data analysis module,a first storage module, a first printing task management module, a first display module, a first printing module, a first fixed value check module and a first network communication module; the primary station subsystem comprises a second network communication module, a second printing task management module, a second data analysis module, a second storage module, a second display module, a second printing module, a second fixed value check module and a printing information publishing module; and the first network module of the substation subsystem is interconnected with the second network module of the primary station module by means of a network so as to implement data synchronization between the substation subsystem and the primary station system. According to the system, printing access of various relay protection apparatus can be implemented, networked printing is implemented, and meanwhile, stable and reliable printing data transmission is ensured.

Description

technical field [0001] The invention relates to a networked printing system of a relay protection device, which belongs to the technical field of electric power data digital processing. Background technique [0002] When the power system components (such as generators, transformers, transmission lines, etc.) fail to endanger the safe operation of the power system, the relay protection device can send a warning signal to the operating personnel on duty in time, or directly issue a trip command to the controlled circuit breaker An automated measure and device to terminate the development of these events. At the same time, the relay protection device will print the on-site situation data through the printer connected to it 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 interferen...

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 device is not equipped with a printer), in this case, personnel are required to go to the site for temporary installation printer, and bringing in AC power, is also 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 processing of paper documents becomes quite cumbersome, reducing It improves the processing efficiency and prolongs the time to deal with the accident, obviously causing some troubles to the use
