| Abstract: | The paper puts forward a concept of the eigenvalue sensitivity on the torsional vibration of tur- bine-generator shaft,as well as a method for calculating the inherent frequence sensitivity under the conditions without damping.Two kinds of generating units:300MW units in YuanbaoShan Plant and a nation-made 200MW units are taken as examples for calculation and analysis.And the ways for im- proving the unsatisfactory inherent frequency of torsional vibration are also deduced. |
