Determination of resonance frequencies of electromechanical vibrations of gas turbine power stations

Abstract

The article deals with the problem of occurrence of electromechanical resonance interactions in turbogenerators of gas turbine power stations of autonomous power systems of oil and gas fields, leading to torsional vibrations of shaft pipelines. The danger of this phenomenon is estimated. We consider two design scheme for the simulation of resonance. There is determined the natural frequencies for each of the calculation schemes are compared with the data of actual accidents the estimated trends of changes of natural frequencies depending on the power and massiveness of the turbines.
The authors substantiate the danger of such regimes, as well as the need to develop special measures aimed at preventing and eliminating the modes of Electromechanical resonance.
