Reversible francis pump turbine

Francis turbine

In contrast to the Pelton turbine, the Francis turbine operates at its best completely filled with water at all times. The turbine and the outlet channel may be placed lower than the lake or sea level outside,

Francis Type Reversible Pump Turbines (RPTs)

The reversible pump turbine (RPT) is a modified version of a traditional turbine designed to operate in two directions. In turbine mode, it functions like a standard Francis turbine, generating electricity.

Francis turbines may be designed for a wide range of heads and flows. This versatility, along with their high efficiency, has made them the most widely used turbine in the world. Francis type units cover a head range from 40 to 600 m (130 to 2,000 ft), and their connected generator output power varies from just a few kilowatts up to 1000 MW. Large Francis turbines are individually designed for each site to operate with th

Simulation model for Francis and Reversible Pump Turbines

In the paper, simulated turbine characteristics for a high head Francis turbine, and for a reversible pump turbine are compared with laboratory measured characteristics.
