The invention relates to an automatic cylinder opening device and method for a steam turbine cylinder. The automatic cylinder opening device comprises a hydraulic jack, a control unit, a driving loop, a detection unit and a power source; the power source provides ascending or descending power for the hydraulic jack according to driving control of the driving loop; the driving loop controls and drives the power source according to a control signal or an adjusting signal output by the control unit, and controls the load and the speed of the hydraulic jack when the hydraulic jack ascends or descends; the detection unit monitors the running state of the hydraulic jack in the ascending or descending process and outputs a feedback detection signal in the ascending or descending process of the hydraulic jack; and the control unit receives the feedback detection signal output by the detection unit, and outputs the adjusting signal to the driving loop according to the feedback detection signal, or outputs the control signal to the driving loop according to a received operation signal. According to the device and method, power is provided for the hydraulic jack, the precision is high, the cylinder opening time is short, and the efficiency is high.
