This paper explores the application scenarios and effects of satellite remote sensing technology in the field of hydropower dam safety operation through the case studies of geological disaster census in a certain watershed and safety analysis of a hydropower plant that lacks historical deformation data on the ground. The results show that satellite remote sensing deformation analysis technology has the advantages of “wide range, traceability, high dynamics, objectivity and accuracy” compared with traditional means, which can help to identify the safety risks of hydropower station dams on a wide scale and prevent them from occurring; it has the ability to trace back the historical deformation in a long period of time, which can provide technical support for the safety assessment of hydropower station operation and the management of engineering hazards, and can be used in the safe operation of hydropower station dams. It can provide technical support for the safety assessment of hydropower plant operation and management of engineering potential problems, and has good application prospects in the safe operation and management of hydropower plants.
