Reversible pump-turbines need to operate often at off-design operating conditions to
stabilize the electric grid. These operating conditions cause hydraulic instabilities due to the …

To stabilize the operation of pumped storage power station, an orthogonal experimental
design was proposed to optimize the return channel with the splitter blades of the pump …

Pumped storage power is the most mature and cleanest energy in the world, which is
universally used in energy recovery fields. As the pumped storage units operate at part-load …

Pumped storage units often deviate from the optimal operating conditions in the process of
regulating new energy fluctuations. To effectively improve the performance of the units, the …

Efficiency and grid stability of pumped storage plants with significant head variations can be
enhanced by the implementation of variable speed operation. The reversible pump-turbine …

The reversible pump-turbine (RPT) operates at off-design operating conditions to balance
the electricity grid due to the high penetration of variable and intermittent solar and wind …

The main objective of this study is to evaluate the hydraulic performance and cavitation
characteristics of Francis turbine at different operating conditions by varying the number of …

Francis turbines have a leakage loss from the corresponding labyrinth seals ie, crown side
and a skirt side labyrinth clearance. Therefore, the labyrinth clearance between the runner …
