Recently, the GNSS high-precision displacement monitoring system independently developed by Shenyang Skyeye IT was fully installed and commissioned at the “China Anneng” Hunan Anhua Pumped Storage Power Station project, and has officially entered routine operation. This deployment fills the gap in real-time deformation monitoring across the complex mountainous high-slope areas of the project.

Hunan Anhua Pumped Storage Power Station is a core project for peak shaving and power supply security in the regional new-type power system. The project area features extensive high-steep rock slopes, fault fracture zones at dam abutments, and weak interlayers. Impoundment, heavy rainfall during flood seasons, and periodic water level fluctuations can easily trigger geological risks such as creep, sliding, and collapse of slope masses.

Conventional monitoring methods—such as manual leveling and total stations—require line-of-sight field operations and can only collect data intermittently. They are incapable of capturing millimeter-level early micro-deformations, and monitoring is interrupted under heavy rain, fog, or nighttime conditions, making it difficult to identify precursory signs of slope instability and leaving blind spots in safety management.

The newly deployed GNSS displacement monitoring system leverages Beidou multi-constellation integrated differential positioning core algorithms to achieve continuous millimeter-level three-dimensional displacement monitoring of the dam body and high-steep slopes in the reservoir area. The system covers key risk zones including the main dam, reservoir slopes, diversion tunnel inlets, and cofferdams. It features unattended, 24/7 uninterrupted sensing capabilities, establishing a fully closed-loop safety management system encompassing “real-time monitoring – intelligent analysis – graded early warning – emergency response,” effectively enhancing proactive risk defense capabilities.

The Emergency Operations Department will continue to track the system’s performance, further expand the application of intelligent monitoring technologies in water conservancy and hydropower engineering, and provide technical support for the safe operation of critical infrastructure in the new-type power system.
