一、引言 随着电子计算机技术的普及,水轮机瞬变过程研究的解析计算方法和图解法逐渐被以电子计算机为基础的数值计算方法所代替,数值计算方法的研究越来越受到人们的重视。 克里夫琴科等人对水电站装置的瞬变过程进行了大量研究,用有限差分方法模拟管道系统的水力瞬变,用图解试误法计算水轮机端边界条件。V.L.Streeter等在采用特征线方法时,考虑了水轮机管道系统的水力损失,应用牛顿-雷伏生方法和四
I. INTRODUCTION With the popularization of electronic computer technology, the analytical calculation method and graphic method of turbine transient process are gradually replaced by electronic computer-based numerical calculation method. The research of numerical calculation method has drawn more and more attention. Cliffordco et al. Conducted a great deal of research on the transient process of hydropower station installations. The finite difference method was used to simulate the hydraulic transients of the pipeline system. The graphical test method was used to calculate the turbine boundary conditions. V.L.Streeter et al. Used the method of characteristic line to consider the hydraulic loss of turbine pipeline system. The Newton-Ray method and four
