Hydro Turbine Generator

Listing ID #3537037

Hydro turbine driven generators have a running speed in the range of 187rpm to 1800rpm. In case of hydro turbine generators, the performance requirements will be unique depending on the type of hydro turbine, grid and power house conditions. Generally, these machines are located in remote places where accessibility is very poor and due to such conditions, there is a requirement for high reliability. Further, in case of weak grid conditions, they would require generators to be specially designed for high inertia requirements to absorb frequent tripping and should further have a rugged design to transfer all the forces to foundation smoothly. The rotor assembly requires specialized design, assembly and balance to operate at high runaway speeds.The generators are designed and manufactured for various types of hydro turbines, such as Kaplan turbines, Francis turbines and Pelton turbines. Each of these three turbines has different design requirements with respect to the generators.
