Condition monitoring of pump-turbines. New challenges
Measurement: Journal of the International Measurement Confederation, 2015 At present, pumped storage is the only system to store huge amounts of energy. The surplus of energy in the electrical grid is used for pumping water from a lower to a higher reservoir (pump operation).

Influences of runner blade shape on the transient behaviours of pump-turbines in load rejection
, 2020The transient behaviour of the pump-turbine in load rejection is very complex, and slight changes in runner blade shape may have great influence on it. To understand the underlying flow mechanisms, the load rejection processes of two model pump-turbines ...
