Pressure pulsations, which are cyclic variations in water pressure, can significantly impact the performance and lifespan of hydro turbines by inducing vibration, cavitation, and fatigue. These pulsations can arise from various sources, including rotor-stator interaction, draft tube instabilities, and hydraulic resonance. Excessive pressure pulsations cause increased vibration in the turbine components, particularly the runner, shaft, and bearings. This vibration accelerates wear and tear on these components, reducing their lifesp....
