| Abstract: | 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. |
