Abstract: At present, the external deformation monitoring of hydropower stations is still mainly carried out by traditional manual methods. Research on the testing and application of Beidou high-precision de⁃ formation monitoring technology was conducted in Tianhuangping pumped storage power station. Focus⁃ ing on the specific monitoring scenarios of hydropower dams, starting from improving the receiving equipment and algorithm of the domestic Beidou satellite navigation system for high-precision deforma⁃ tion monitoring, the existing monitoring system has been upgraded and improved. Through the compari⁃ son of dynamic loading displacements, Beidou calculation results and traditional manual observation re⁃ sults, the applicability of the domestic Beidou system in the deformation monitoring of hydropower dams has been verified.

Key words: Beidou, deformation monitoring, testing

摘要： 目前，水电站外部变形监测仍以传统人工手段为主。天荒坪抽水蓄能电站开展了北斗高精度变形监测技 术的测试及应用研究，着眼于水电站大坝特定监测场景，从改进国产自主北斗卫星导航系统高精度变形监测的接 收设备和算法入手，在已有监测系统基础上进行升级改进，经实际动态加载位移、北斗解算结果与传统人工观测 结果对比，效果符合预期，验证了国产北斗系统高精度变形监测技术在水电站大坝安全变形监测中的适用性。
