Remote Intensive Control System of Unattended Substation Automation System

Abstract

The invention relates to a working method of a remote management and control system of an unattended substation automation system. The intensive management and control system includes: a remote virtualization terminal, a remote virtualization patrol module, and a protocol adaptive access module; The virtualization terminal inspects the entire substation automation system through the remote virtualization inspection module, and automatically displays the status information of the inspected equipment in real time; when the equipment is found to be abnormal, the software and hardware of the corresponding equipment are remotely activated through the remote virtualization terminal. stop, that is to realize remote control; at the same time, write the status information of the patrolled equipment into the patrol log; when performing the remote control, for multiple devices using different communication protocols, according to the feature codes in each communication protocol, automatically Identify various communication protocols and convert various communication protocols into one communication protocol, and then start and stop software and hardware.

Problems solved by technology

[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 status of some system background equipment lacks effective monitoring, and after a failure or crash, it is 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 detailed fault information can only be obtained when the operation and maintenance personnel arrive at the scene, and it is impossible to make a judgment and analysis in the first place

Once a failure of the 220kV main network is involved, the superior dispatcher requires a quick submission of the event detailed information report. In the case of an accident involving multiple substations, it will bring greater pressure to the operation and maintenance unit

At the same time, due to the limited failure or abnormal information received by the master station monitoring, it is difficult to judge whether there is a problem with the automation equipment, which brings a certain degree of blindness to the preparation work of emergency repair spare parts, often affecting the work efficiency of emergency repair

[0003] Using the method of going to the site to conduct regular inspections, check the fixed value, and evaluate the operating status of the automation system in the station also takes up a lot of manpower, vehicles, and time resources
