THE MATHEMATICAL MODEL OF TURBO-GENERATOR SET AS A CONTROL OBJECT IN CONSIDERING WITH THE TORSIONAL OSCILLATION CHARACTERISTIC

Abstract

Abstract: As to research the influence of control system on the turbo-generator shaft torsional oscillation, in this paper the mathematical model of the turbo-generator shaft system from the point of view of automatic control is given. The discussion begins from a simple physical model, the frequency characteristic of the shaft system is given in considering with the torsional oscillation, and some basic problems and conclusions are discussed. On these bases the mathematical model of a multi mass-spring shaft system is introduced too. At the end of this paper the calculation results of a multi mass-spring shaft system are given.
