    The torsional vibration characteristics of the hydro-generator set considering the electromagnetic and hydraulic vibration resources
    coupling are studied The moment of rotation consists of water flow driving and magnetic torques caused by the air gap magnetic
    field in the generator rotor in the case of ignoring the mechanical friction. A coupling torque vibration model of hydro-generator shaft
    system was established The model considered the coupling action of hydraulic and electromagnetic excitations, as well as the elastic
    effect of rotor spiders. The influences of the rotor moment inertia, rotor stiffrzess, and mass of turbine water added into the torsional
    natural vibration of the unit shaft system were studied The effect of hydraulic excitation frequency on torsional vibration response
    was also investigated The frequency response curves of shaft torque, torsional vibration angle, and electromagnetic torque were
    presented The electromagnetic and hydraulic coupling resonance was studied when hydraulic excitation frequency was equal to zero
    and first-order frequencies. The excitation electric current and internal active power angle on torsional vibration was further
    analyzed This study provides an analysis model and method considering the coupling of electromagnetic and hydraulic vibration
    resources for design and stable operation of water turbine generator sets.
