Zusammenfassung:	The invention belongs to the technical field of power mechanical engineering, and particularly relates to a dynamic balance method and device for a flexible supporting steam turbine generator unit. The method comprises the steps that mathematical models of a rigid support rotor and a flexible support rotor are established, dynamic balance response coefficients of the rigid support rotor and the flexible support rotor under the influence of different vibration modes are simulated and calculated in the mathematical models, and a difference coefficient curve of the dynamic balance response coefficients between the flexible support steam turbine generator unit and the rigid support is obtained; according to the actual dynamic balance influence coefficient of the previous rigid support rotor obtained in advance, the dynamic balance influence coefficient of the flexible support rotor is obtained through correction of the difference coefficient curve; and formulating a dynamic balance scheme of the flexible support
