Vibration Control and Condition Monitoring of Turbine Alternator in Hydro Electric Power Plants

Sridharan. P

Abstract :

Handling of large power generating units and keeping the size of the turbine generator sets are economically small that requires higher running speeds, which means greater pressure differences between the two sides of the vanes of a runner. These forces also cause viations of the stator which are transmitted through the frame to any adjoining structure, cavitations due to discharge causes the main viation effects in most of the hydroelectric power plants. Viation faults in the generator subject to stresses beyond its design limits and cause high temperature increase, amplify and distort air gap torques, and create unbalanced flux densities. Alternating magnetic forces in the air gap between the stator and rotor of the machine are essential for the working of the machine. An air injection setup is introduced to control cavitation bubbule and for smooth operation of the turbine Generator sets.
