Abstract: Power transformation and distribution station is an important part of the power system. The geological and topographic conditions of the area through which the distribution station passes are complex and vulnerable to geological disasters. In order to avoid the damage caused by geological disasters to the power transformation and distribution station and improve the safety of the power transmission and distribution system, an effective means is to monitor the micro displacement of the area where the power transformation and distribution station is located. Considering that the distribution station is sometimes deployed in no man’s land and the communication environment is complex, the global positioning system precision single point positioning method is used to continuously observe the substation for 11 months. After model correction and solution, the accuracy of the monitoring data can reach millimeter level. In addition, through the analysis of precipitation in this area in the same period, geological displacement and settlement mainly occur in the time period with abundant precipitation. This shows that the precise single point positioning method has a good application prospect in the monitoring and early warning of geological disasters in power transformation and distribution stations, and can effectively ensure the safety of power transmission and distribution system.
