Substation equipment dispatching monitoring system and method

Abstract

The invention discloses a substation equipment dispatching monitoring system and method. The system includes a substation dispatching service center which communicates with a remote management and control system, a station environment detection device, a fault recording monitoring module, a remote control module, a fault monitoring module and a power grid dispatching alarming and monitoring modulethrough communication cables. The beneficial effect is as follows: the substation automation system is automatically inspected through the remote management and control system, so that the work efficiency of substation automation equipment abnormality and power system fault analyzing and processing is improved, and complete and real-time collection of fault data is realized.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to a substation equipment scheduling and monitoring system and method. Background technique [0002] Power dispatching is an effective management method adopted to ensure the safe and stable operation of the power grid, reliable external power supply, and orderly progress of various power production tasks. The specific work content of power dispatching is based on the data information fed back by various information collection equipment, or the information provided by monitoring personnel, combined with the actual operating parameters of the power grid, such as voltage, current, frequency, load, etc., to comprehensively consider the development of various production tasks , judge the safety and economic operation status of the power grid, issue operation instructions through telephone or automatic system, and direct on-site operators or automatic control systems to m...

AI Technical Summary

Problems solved by technology

[0004] The existing monitoring system for substation equipment dispatching is limited to the local substation in terms of communication, and does 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 after the operation and maintenance personnel arrive at the scene, and it is impossible to make a judgment and analysis in the first time; at the same time, the security of the substation data communication cannot be effectively obtained. Guarantee

[0005] The fault recorder is an automatic recording device that is put into operation all the year round to monitor the operation status of the power system. If the communication of the fault recorder is found to be interrupted, the protection personnel need to go to the scene to cut off the power of the fault recorder and restart it; however, due to the The substation is generally far away from the urban area, so it takes a long time for the protection personnel to arrive at the scene. This process not only increases the fault elimination time of the fault recorder, increases the possibility that the fault recorder cannot record normally when the power grid fails, but also increases Increased on-site work intensity of protection personnel

[0006] Considering the safety of equipment and personnel in the substation, the insulation degree of communication cables in the substation is relatively high. Therefore, the electrical performance of the insulating material in the substation is directly related to the voltage level and safety of the entire substation; the current communication cables have been used for a long time. Under the action of DC high voltage, it is still possible to cause surface flashover due to charge accumulation

[0007] Therefore, the existing substation dispatching and monitoring process still has the problems of poor communication stability, low communication reliability and failure to deal with equipment failures in time
