Abstract

This article conducts numerical calculations on the head cover bolts of the pump turbine in Yixing Pumped Storage Power Station under typical steady-state and transient conditions and analyses the force characteristics of the coupling bolts under turbine, pump, pump zero flow and load rejection conditions. On this basis, further evaluation of head cover bolts safety and reasonable suggestions for subsequent operation are provided.
