Abstract
A method for measuring the vibration behaviour of a drivetrain of a turboset including a generator in a power plant connected to a power network, includes: a) selecting exciter signals, wherein the frequency spectrum extends significantly beyond the frequency range usual from the commissioning of pendulum damping devices, b) influencing the field current of the generator using the exciter signals such that mechanical vibrations are excited in the power plant turboset, c) measuring the excited mechanical vibrations including the resonance vibrations by measuring at least one suitable output variable, d) determining a transfer function from the exciter signal to the output variable measured, and e) determining the transfer function from the generator torque at a desired output variable using known transfer functions of the exciter signal at a desired input variable and/or of the desired output variable for the output variable measured on the basis of the transfer function determined.
