摘要:

介绍了基于模型综合特性曲线的外特性法、基于内特性解析模型的内特性法和基于简化非线性模型的简易解析法等3种混流式水轮机传递系数的计算方法,分析比较了它们的特点和计算结果的差异,指出三种方法计算所得传递系数,在额定功况点附近数值较接近,而在轻载工况下则差别较大.所求取的传递系数曲线对认识其变化规律有所裨益.

Abstract:

The calculation methods of the transfer coefficient of three francis turbines, namely the external characteristic method based on the comprehensive characteristic curve of the model, the internal characteristic method based on the internal characteristic analysis model and the simple analytical method based on the simplified nonlinear model, are introduced, and the differences between their characteristics and calculation results are analyzed, and it is pointed out that the transfer coefficient calculated by the three methods is close to the rated power point and the difference is large under the light load condition. The obtained transfer coefficient curve is helpful for understanding its variation law.
