摘　　要：针对不规则的离散水轮机特性数据,提出一种求取水轮机特性曲线的随机插值点方法。即利用MAT-LAB对离散数据进行采样,然后应用Delaunay算法对采样的数据进行三角剖分,并通过三次样条函数插值,保证其计算精度。通过某水电站的HLPO140-LJ-485的数据验证,该方法可行有效。According to the irregular discrete characteristic data of turbine, this paper put forward a kind of random interpolation method to get the turbine characteristic curve. The discrete data were collected by MATLAB and treated by Delaunay algorithm, through the three spline interpolation, the precision turbine characteristic curve was obtained, The calculation precision was verified through a turbine HLPO140-LJ-485 at a hydropower station.
