Thermal power plant rotating machine vibration control method

The invention relates to a thermal power plant rotating machine vibration control method, which comprises the following steps of 1, based on a rotating machine vibration speed root-mean-square reference value, obtaining a corresponding vibration control limit value according to the power, the supporting mode and the type of a rotating machine, wherein the vibration control limit value comprises a vibration qualified value A, a first alarm value B, a second alarm value C and a shutdown value D, and the rotating machine comprises a pump, a fan and a motor, and 2, according to the obtained vibration control limit value, carrying out vibration hierarchical control on the rotating machine. Classified control is carried out according to the power, the supporting mode and the type of the rotating machine of the thermal power plant, unified control can be carried out on the vibration condition of the rotating machine of the whole plant, full-period management is carried out on the vibration of the unit, and the metho
