TURBINE BLADE MAXIMUM RESPONSE PREDICTION METHOD, TURBINE BLADE MAXIMUM RESPONSE PREDICTION SYSTEM AND CONTROL PROGRAM, AND TURBINE EQUIPPED WITH TURBINE BLADE MAXIMUM RESPONSE PREDICTION SYSTEM
To provide a turbine blade maximum response prediction method, a turbine blade maximum response prediction system, a turbine equipped therewith, and a control program making it possible to predict and evaluate the vibration response of all the moving blades even in a case where it is impossible to measure the vibration response of all the moving blades.;A turbine blade maximum vibration response prediction method for predicting a maximum vibration response acting on a plurality of turbine moving blades 1 provided along the circumferential direction of a turbine rotor 6 includes the steps of: gaining, before turbine operation start, prior response data that is distribution data on vibration response of all the turbine moving blades 1 for each turbine operating condition; gaining, by using the prior response data, operation response data that is distribution data on the vibration response of all the turbine moving blades 1 during the operation of the turbine; and predicting, from the operation response data, the turbine moving blade 1 of all the turbine moving blades 1 on which the maximum vibration response is acting, and the magnitude of the maximum vibration response.
