Protocol self-adapting access method of intensive management and control system of unwatched transformer substation

Abstract

The invention relates to a working method of a remote management and control system of an automatic system of an unwatched transformer substation. The intensive management and control system comprises a remote virtual terminal, a remote virtual patrol module and a protocol self-adapting access module. In work, the working method comprises the steps that the remote virtual terminal patrols the whole automatic system of the transformer substation through the remote virtual patrol module and automatically displays state information of patrolled equipment in real time; when the equipment is found to be abnormal, the remote virtual terminal starts and stops the software and the hardware of the corresponding equipment remotely so as to realize the remote management and control; the state information of the patrolled equipment is written into an alternate patrol log; during the remote management and control, for multiple pieces of equipment adopting different communication protocols, the different communication protocols are automatically recognized according to feature codes of the different communication protocols and converted into one communication protocol; and then the software and the hardware are started and stopped.

Description

technical field [0001] The invention relates to the technical field of remote management and control of unattended substations, in particular to a protocol adaptive access method for an intensive management and control system of unattended substations. Background technique [0002] The existing unattended substation is equipped with comprehensive automation system background equipment, fault recording information system and other equipment, which can collect detailed information, working conditions, event information, etc. of all connected equipment, but the communication is limited to this substation , did not achieve remote transmission. Therefore, the operation of some system background equipment lacks effective monitoring, and failures or crashes are often not found and dealt with in time for a long time, which brings hidden dangers to its proper function. Once the equipment is abnormal, the signal received by the master station monitoring is usually too simple, and the...
