D elaunay 三角剖分在水轮机特性曲线处理中的应用

摘要

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 .%　　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。
