Description

Technical field [0001] The invention belongs to the technical field of power system automation, and specifically relates to an online monitoring system and method for the inclination angle of a power system iron tower. Background technique [0002] Due to earthquakes, drop in groundwater level or go-out of underground coal mines, changes in the geology of the large slab foundation of the power system tower are likely to cause the large slab foundation to tilt, causing the tower to tilt horizontally or along the line. When it reaches a certain level, the root opening of the tower and the height difference of the tower legs will change, and the tower structure will produce a large additional stress. In severe cases, the tower will be partially damaged or collapsed as a whole. It will be affected by wind, ice, etc. Under external force conditions, it is easy to collapse, directly threatening the safety of the tower and the stable operation of the line. In addition, under severe wea...

AI Technical Summary

Problems solved by technology

[0002] Due to earthquakes, groundwater level drop, or underground coal mine mining, etc., the geology of the power system tower slab foundation changes, which may cause the slab foundation to tilt, making the tower tilt horizontally or along the line. When the inclination angle When it reaches a certain level, the height difference between the root opening and the tower legs of the iron tower will change, and the tower body structure will generate a large additional stress. Under external force conditions, it is easy to collapse, which directly threatens the safety of the tower and the stable operation of the line

In addition, in severe weather such as extremely strong winds and snow-covered lines, the tower will tilt. If the tilt angle is too large, the tower will collapse and the power supply line will be interrupted. Therefore, it is necessary to monitor the tilt of the power system tower , which is directly related to the safe and stable operation of the power system, and will also affect the intelligentization process of the power grid

[0003] In the past, the detection of the tilting status of the power system tower was mainly completed by manual regular line inspection. This method has a low degree of automation and high labor costs. The most important thing is that real-time monitoring cannot be achieved, and there are potential safety hazards for the safe operation of the power system.
