水轮机水锤法测流数学模型的研究

STUDY OF MATHEMATICAL MODEL OF HYDROTURBINE DISCHARGE MEASUREMENT BY GIBSON METHOD

对于水锤法测量水轮机流量,本文提出了用弹性理论进行误差修正的数学模型,并将这模型在计算机上实现,从而分析出弹性理论(或刚性理论)、回复水头的试算、漏水量诸因素对测量结果的影响。

This paper concerns the study of measuring the hydraulic turbine discharge with gibson method, how to eliminate the theoretical error based on rigid-column theory is particulary discussed. With putting this theory into effect on IBM Personal Computer, the paper analyzed how the result was effected by such factors as elastic-shock theory (or rigid-column theory), the trial method of hydraulic recovery head and leakage flow.
