Abstract: Abstract The S-shaped characteristic of a pump-turbine poses a latent risk to problems such as failure to start the unit, excessive water hammer pressure after load rejection, severe pressure pulsation, and intense vibration. However, S-shaped… read more here.

Abstract: The frequency of high head pump turbines easily fluctuates under the low head no-load condition, which makes it difficult to achieve the synchronous grid connection. In this study, a new start-up strategy of linkage between… read more here.
