Inversion Calculation and Analysis of Transient Process for Pumped Storage Power Station

Abstract

In order to more accurately evaluate the transition process characteristics of pump turbine in pumped storage power station, this paper summarized a systematic inversion calculation and analysis method. Using this inversion calculation method, this paper calculated and analyzed the pressure changes for different load conditions of the same unit, similar conditions of other units in the same hydraulic unit and similar conditions of similar units in other hydraulic units based on the actual measured data of load rejecting test in a pumped storage power station. The inversion calculation results are in good agreement with the experimental measured data, which proves that it is feasible to predict the transient pressure by using this method for inversion calculation.
