Computational research on the formation mechanism of double humps in pump–turbines

Engineering Applications of Computational Fluid Mechanics, 2021
The hump formation mechanism has not been fully understood so far, mainly because of two difficulties in analysis. The first one is how to find the most important external characteristic factor inducing humps, and the other is how to avoid too many ...

Review of positive slopes on pump performance characteristics of pump-turbines

Renewable and Sustainable Energy Reviews, 2019
Positive slopes in the performance characteristics of pump-turbines are an indicative feature of unstable behaviour in pump mode operation, and are additionally conducive to instability problems during pump start-up.

Evaluating the pressure fluctuations during load rejection of two pump-turbines in a prototype pumped-storage system by using 1D-3D coupled simulation

, 2021
Load rejection is one of the dangerous transient scenarios in pumped-storage power stations (PSPSs), and the risk should be evaluated from design to operation stages of PSPSs.
