Abstract

With the upgrading of the world energy resources structure, the proportion of clean energy has gradually increased, and investment in the construction of Pumped Storage Power Station has increased around the world. As the core component of energy conversion, studying the operational stability of pump-turbine is of great significance. This study focuses on the hump region of reversible pump-turbine in pump mode, using experimental testing methods, energy experiments are conducted with different guide vane openings and flow rate coefficient. Besides, the hump coefficient is defined to quantitatively analyze the hump characteristics. Combining quantitative and qualitative analysis, research has shown that the hump coefficient is relatively high under small guide vane opening and small flow rate, indicating that the hump phenomenon is more obvious, and unstable operation has occurred under this operating condition. At the same time, this study also provides a reference for relevant research in terms of analytical and research methods.
