Intelligent detection and analysis system for grounding resistance of transformer substation

Abstract

The invention discloses an intelligent detection and analysis system for grounding resistance of a transformer substation. The system comprises a central processing unit used for controlling the system to carry out corresponding rural detection and data processing operation according to an operation instruction sent by a remote terminal, and processing corresponding data information generated in the resistance detection and data processing process; and a data sotrage unit. According to the invention, through the arrangement of a resistance detection unit and a data acquisition unit, the grounding resistance of the transformer substation can be detected and the data of the surrounding environment can be acquired at the same time, meanwhile, a remote communication unit is matched to carry out remote control measurement and data transmission operation, and through the arrangement of a data comparison unit, the current data can be automatically compared with the original data, thereby obtaining the change value of the grounding resistance of the current transformer station, automatically generating a monitoring report and giving a conclusion or a processing measure. Manual on-site detection data comparison and processing are not needed, so that the detection efficiency is greatly improved, and the practical application is facilitated.

Description

Technical field [0001] The invention belongs to the field of power engineering, and is specifically a substation ground resistance intelligent detection and analysis system. Background technique [0002] In the existing life, the substation grounding network is generally calculated after the initial calculation and laying, but in the actual use process, the grounding resistance of the substation will change at any time, affecting The main factors of the grounding resistance are terrain, geological conditions, followed by weather conditions such as climate conditions and sun, and rain, there are also factors such as land area, because the grounding resistance value of the grounding network is changed at any time during use, and Its change is to gradually decrease over time, and when the resistance value of the substation ground net is exceeded, the accident, crisis countries and individual safety will be easily detected, so real-time detection of substation ground resistance is mo...

AI Technical Summary

Problems solved by technology

[0002] In the existing life, after the initial calculation and laying of the substation grounding network, the subsequent resistance value is generally not measured, but in the actual use process, the substation grounding resistance will change at any time, affecting The main factors of the resistance of the grounding grid are terrain and geological conditions, followed by climate conditions and meteorological conditions such as sunshine and rain, and other factors such as the area of ​​the grounding grid. Since the grounding resistance value of the grounding grid changes at any time during use, and Its change will gradually decrease with the passage of time. When the resistance value of the substation grounding grid exceeds the fixed range, accidents will easily occur, endangering the safety of the country and individuals. Therefore, it is more important to detect the grounding resistance of the substation in real time.

[0003] However, when the existing substation grounding resistance intelligent detection system is actually used, most of them are detected manually through the measuring device on the spot. Compared with the original grounding network resistance, it is impossible to obtain the change value of the current substation grounding resistance. Therefore, if you choose to measure manually, you need to compare and process the detection data repeatedly, which greatly reduces the detection efficiency, which is not conducive to practical application
