Research on Monitoring and Early Warning of Substation Geological Subsidence Based on High-Precision Beidou Positioning

Abstract

The geological subsidence of substations is sudden and complex, and its rapid and accurate monitoring and early warning is of great significance to the safe and stable operation of the power system. This paper presents a method for monitoring the geological subsidence of substations with high-precision Beidou positioning technology. On the one hand, it can optimize the PTK technology, and on the other hand, it can comprehensively process the data of the reference station and monitoring station and use the reference station as a reference to grasp and understand. The deformation of monitoring points ensures the accuracy of monitoring. In this paper, the output of pseudorange, carrier phase and other information of high-precision Beidou satellites is used to meet the requirements of positioning solution. Secondly, the principle of vertical and horizontal displacement monitoring of geology substations of high-precision Beidou satellite receivers is given. Finally, the settlement is given. The selection principle of monitoring base station, monitoring station and communication network. The high-precision Beidou positioning monitoring method proposed in this paper can quickly, real-timely, and accurately monitor and warn the geological subsidence of substations, changing the previous situation of manual monitoring of geological subsidence.
