Abstract

Abstract:

Reservoir capacity is a critical indicator for the operation and maintenance management of pumped-storage power stations. However, traditional surveying methods, due to insufficient point density, fail to accurately reflect the actual conditions of complex terrain, resulting in significant errors in reservoir capacity calculations that make it difficult to meet high-precision calculation requirements. Taking a specific pumped-storage power station as an example, this paper uses UAV-mounted LiDAR and USV-carried multibeam bathymetric system to acquire high-density, high-precision topographic data above and below the water surface, respectively. High-precision TIN models of the upper and lower reservoirs are constructed to calculate reservoir capacity, plot water level-reservoir capacity curves, and establish a polynomial function model. Experimental results demonstrate that this method can achieve low deviation rate in capacity calculation, and can provide technical references for refined management of reservoirs with complex terrain.

Key words: accurate calculation, airborne LiDAR, multibeam bathymetry, reservoir capacity calculation, TIN, polynomial

摘要：

库容是抽水蓄能电站运维管理的重要指标。传统测量手段因点密度不足，无法反映复杂地形的实际情况，库容计算误差较大，难以满足高精度计算要求。笔者以某抽水蓄能电站为例，通过无人机机载LiDAR与无人船载多波束测深系统分别获取水上及水下高密度、高精度地形数据，构建上下水库高精度TIN，实现库容计算与水位-库容曲线绘制，并建立多项式函数模型。试验表明，该方法库容计算偏差率较小，可为复杂地形水库的精细化管理提供技术参考。
