| 摘 要： | 给出了一种新的水泵水轮机全特性的表达方式，在这种表达方式中单位参数（如单位力矩，单位转速及单位流量）是全特性曲线图中等开度线长度的函数。算例表明，该方法克服了原有特性曲线存在的多值性，使小开度区特性得到很好的表达，使有限开度特性与另开度特性之间有良好的衔接。应用该模型进行了为获得调压井涌浪极值的复合工况计算

New representation of the complete characteristics of pump turbine and the calculation of complex operating conditions |
| |
| Abstract: | A new representation of characteristics of the pump turbine for use in calculation of transients is given, in which the unit parameters (for example unit torque, unit speed and unit discharge) are functions of lengths of the equal opening lines in complete characteristics curves of the pump turbine. Besides overcoming multivalued problem in the representation the limiting opening and the zero opening are well connected with each other so far as their traits are concerned. The representation also shows the characteristics of the small opening area of pump turbine. The transients of complex operating conditions in pumped storage power station, in which the extreme values of the surge parameters of the surge tank are produced, are calculated. |
