Abstract

For 200MW turbo-generator system, considering higher order and higher dimension of nonlinear differential equations governing the motion of its rotor-bearing system, the Mechanized Mathematics Method can be used as modeling and analyzing means of rotor-bearing system in order to obtain the analyzed solutions of the 200MW turbo-generator system. When the order of the differential model has been reduced by fixed interface mode synthesis method, it may be transformed into an algebraic expression set by Wu Elimination Method (WEM). Then lower dimension algebraic equations included nonlinear oil force expressions are obtained, because of the nonlinear parts of oil force expressions can be remained after eliminating the linear coupling variable of node displacements of rotor-bearing system of 200MW turbo-generator system. Differential Control Method (DCM) that is different to analyzed method and the classical numerical method was presented in this paper. According to proposed method the model of 200MW turbo-generator system has been described and its node displacement response of system was analyzed and predicted. The analysis results based on proposed method stand with very good agreement with previous numerical calculate results.
