Summed up in this paper are the recent research results available both at home and abroad concerning the suppression of shafting torsional oscillations in a large sized turbogenerator. The coverage focuses on a variety of factors liable to cause shafting torsional oscillations, such as series capacitance compensation, direct current transmission system, control system as well as related control techniques involving the use of supplementary excitation control, etc. New methods for analyzing the mechanism and law of the shafting torsional oscillations have been introduced, which are based on the employment of such nonlinear theories as dissipative structure theory, chaos and catastrophe ones. In addition, a novel conception is proposed to implement an intelligent control of the shafting torsional oscillations along with a prediction of the development trends in this research field.
