Abstract: The complete characteristic curve of the pump turbine show "s" characteristic in the
anti-pump and pump working-condition. The multi-numerical values of unit discharge and unit
moment the curve caused by crossover and overlap phenomena of the curve may bring
inconvenience for transition process analysis. In this paper, complete characteristic curves of the
pump turbine were dealt with using improved Suter curve transformation method. A surface
fitting were carried out for transformed WH curve. Therefore, a three-dimensioned surface was
achieved. The transition process of load shedding was analyzed using the curve above-mentioned.
The results show that the method used in the paper can eliminates the uneven distribution,
crossover, overlapping and multi-value characteristic, thus providing convenience for the
transition process analysis of pump-turbine. © Published under licence by IOP Publishing Ltd.
