水调系统等雨量线生成算法研究

Study of isohyets generation algorithm in reservoir dispatch automation system

等雨量线需要通过网格化、插值和追踪来生成.对等雨量线生成的相关算法进行了研究,提出采用Delau-nay三角形进行网格化,并说明了在网格上插值和等值点的追踪方法.以凤滩水库所在酉水流域的雨量分析为例,验证了算法的可行性.最后展望了等雨量线生成需要进一步研究的问题.

The isohyets generation algorithm is studied. Delaunay triangulation meshing is proposed. Interpolation in meshes and contour tracing are also illustrated. The algorithm is implemented in Fengtan Reservoir dispatch automation system for Youshui River watershed. At last further problems about isohyets are listed.
