摘要
采用足够小的直线段拟合机组全特性曲线平直部分,采用二次多项式拟合机组全特性曲线弯曲部分,推导了有关方程,并对模拟的方程进行了处理,编制了较通用的计算机程序,利用该计算机程序对我国蒲石河抽水蓄能电站进行了计算分析,计算结果表明:该计算机程序计算速度较快、计算准确度较高,提出的水泵水轮机的数值模拟方法具有实用价值.
In this paper a method of numerical simulation of pump-turbines is described. The straight parts of the unit complete characteristic curves are derived by short enough straight lines interpolation and the rapidly varying parts of the unit complete characteristic curves are derived from the quadratic equations. The simulation equations are derived and simplified and a computer program has been designed. The method is used to calculate the transient flow in the pipe system of the Pushihe pumped storage plant. The calculated results show that the method is accurate and useful in practice.
