Preliminary analysis on risk and process of powerhouse flooding in a pumped storage power sta-tion
With the expansion of layout scope and construction scale of pumped storage power stations,the flood threat to underground powerhouses is becoming increasingly serious.From the perspective of risk analysis of the powerhouse flooding emergency in pumped storage power stations,it is divided into water permeation scenarios such as upstream water diversion system leakage,unit pipe leakage,draft tube leakage and rainwater backflow.Taking a pumped storage power station as an example,the inunda-tion processes under different permeation scenarios were analyzed and calculated based on the gate opening and closing situation,and corresponding emergency disposal measures were proposed for differ-ent leakage sources.
