摘要

水泵水轮机的全特性曲线在曲线两端存在较为严重的交叉、聚集和卷曲现象,以及极不稳定的“S”型区域,为水泵水轮机过渡过程的精确仿真带来了极大的困难。针对这些现象和“S”型区域存在的问题,国内外学者进行了深入地研究,通过对全特性曲线预处理数学变换方法和拟合手段的探讨,最终得到一系列研究成果。综述了现有的全特性曲线研究成果,将研究成果按照表述方法分为二维曲线数学变换和三维曲面拟合2大类,依次对各个研究成果进行简要介绍和深入分析,指出各研究成果取得的突破和不足,提出了进一步深入研究的方向和研究的建议。

Abstract

Intersection, aggregation, intertangling and the extremely unstable S-shape area on both ends of the characteristic curve of pump turbine pose great difficulty for the accurate simulation of pump turbine’s transition process. In view of this, scholars both in China and abroad conducted in-depth researches on the mathematic transform and the fitting method for characteristic curve. In this paper we summarize the research achievements. According to the expression method we divide the research results into two-dimensional mathematical transformation and three-dimensional curved surface fitting. We also point out the breakthrough and insufficiency of the research results, and finally propose the direction and several suggestions for further research.
