Abstract

As a flexible and adjustable source of high-quality clean energy, pumped storage power stations (PSPs) play a crucial role in stabilizing power grids. The transient performance of PSPs during transition processes directly impacts power station safety and grid stability. During the design phase, extreme transient low pressure is a key concern for decision-makers. However, the comprehensive effects of system parameters on the minimum pressure in the draft tube (HDT-min) remain unclear, and a systematic analysis framework is lacking. This study establishes a systematic analysis framework to provide more robust reference standards and calculation criteria for design decision-makers. Using an actual PSP in China as a case study, the influence of system parameters on extreme transient low pressures was examined. The results indicate that D3 and L2 have the most significant impacts on HDT-min. Reducing D3 and L2 by 90 % improved HDT-min by 78 % and 90.85 %, respectively. Furthermore, repositioning the upstream branch pipe forward and the downstream branch pipe backward effectively enhanced HDT-min without significantly increasing project costs.
