PROBLEM TO BE SOLVED: To provide a combustion vibration controlling system and method for gas turbine capable of restraining even combustion vibration of a high frequency and a synthetic wave. SOLUTION: The combustion vibration controlling system comprises a magnetic metal wafer constituting a part of the wall section of the combustor case of the gas turbine, a solenoid coil provided faced to the metal wafer, a pressure sensor, which is attached to the combustor case, for detecting the inner pressure of the combustor case or a vibration sensor for detecting the vibration in the inner and outer directions of the combustor case, and a controller for supplying exciting power to the solenoid coil and exciting the metal wafer in the inner and outer direction of the combustor case based on the inner pressure of the combustor case, which is detected by the pressure sensor or the vibration in the inner and outer direction of the combustor case, which is detected by the vibration sensor by the electromagnetic force of the solenoid coil. The vibration phase of the metal wafer is set and combustion vibration is restrained using the combustion vibration controlling system. COPYRIGHT: (C)2004,JPO
