Effect of turbine's torque and speed variation on hydraulic vibration analysis during transient processes

Aili Shen,
Weijie Cui,

et al.

Abstract: With the rapid development of large‐capacity hydraulic turbines and pumped‐storage power stations, hydraulic vibration analysis attracts increasing attention nowadays. To explore the influence of torque and speed variation on hydraulic vibration characteristics during transient processes and ensure the stability of hydropower stations, an improved analytical formula of turbine impedance involving the torque and speed variation was then derived. The free vibration analysis and forced vibration analysis using th… Show more
