Pump turbine

Pump turbines are characterized by their ability to operate both as turbines and as pumps. They are primarily used in pump-storage hydroelectric plants as a means of load balancing by producing electricity during peak demand and operating in pump mode when surplus power is available. Ensuring an optimal fulfillment of these tasks presents a number of technical challenges: 

  • Short synchronization times  
  • Frequent change in operating mode between pump and turbine 
  • Short response times are necessary 
  • Broad operating range (partial load) is desired 
  • Improved reliability and availability 
  • Reduction of failure occurances (increasing safety) 

The aim of research into pump turbines is a better understanding of the flow conditions, which can lead to instabilities (recirculation, flow separation, vortex formation and development, flow obstruction, stall,...). As a result, new guidlines for the design of pump turbines and their components can be derived, allowing for a broadening of the operating range of the pump turbine while avoiding instabilities.
