| 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 transfer coefficients of hydroturbine linear model have important effect on the analytic results of stability and dynamic behavior of hydoelectric generating unit.Three algorithms are induced which include external characteristics based on model synthetical characteristics curves of hydroturbine,internal characteristics based on internal analytic model and analytic method based on simplized and nonlinear model in the paper.Their features and difference of results are analyzed.The given charts of transfer coefficients do good on realizing their variational law. |
