Intelligent platform for live operation inspection of transformer substation

Abstract

The invention discloses an intelligent platform for the live operation inspection of a transformer substation. The platform comprises a transformer substation operation inspection controller which communicates with a remote management and control system, an in-station environment detection device, a remote control module, a fault monitoring module, and a cable operation state detection module through communication cables. According to the invention, by means of the remote management and control system, a substation automation system is automatically inspected. The working efficiency of substation automation equipment abnormity and power system fault analysis and processing is improved. Meanwhile, the complete and real-time collection of fault data is achieved.

Description

technical field [0001] The invention belongs to the technical field of power grids, and in particular relates to an intelligent platform for substation live inspection. Background technique [0002] Intelligent operation inspection is an effective monitoring method adopted to ensure the safe and stable operation of substations, reliable external power supply, and orderly progress of various power production work. [0003] The daily live inspection of substations is to find possible faults in substation equipment through intelligent inspection, prevent problems before they happen, and ensure timely maintenance of faulty equipment. [0004] The existing substation equipment operation and inspection system is limited to the substation in terms of communication, and does 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, whic...

AI Technical Summary

Problems solved by technology

The cable trench is often tens of meters or even hundreds of meters long. The external environment is complex, rain erosion, and small animals gnaw on the cable, causing damage to the cable, resulting in a decrease in the cable insulation in the cable trench, resulting in protection malfunction, signal error, and cable insulation reduction. The phenomenon of grounding will also increase the uncertainty of the safe and reliable operation of other substation equipment and power grids

[0006] Usually, once a cable fails, it will be difficult to find it. If it is not handled in time, it will cause inestimable power outage losses; when performing cable maintenance, operation and maintenance personnel need to observe in a narrow space, due to insufficient space and light Insufficient, it is difficult to carefully observe the defects of cable equipment, and it is often impossible to effectively observe and record the hidden dangers of cable equipment in the cable trench. big inconvenience

[0007] 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

[0008] Therefore, the existing substation inspection process still has the problems of poor communication stability, low communication reliability, and failure to deal with equipment failures in time
