Non-Linear Mathematical Model of the Dynamics of a Turbine for Saturated Steam.

摘要

The paper presents a nonlinear mathematical model of the dynamics of a turbine for saturated steam installed at a nuclear power station. The model enables an analysis to be made of the transient processes in the turbine flow section caused by various external disturbances. The concept and structure of the model for a typical construction are shown. The relationships describing mass and energy storage processes, as well as the properties of the turbine flow section components are presented. The model is given in the form of a set of differential equations, ordinary, nonlinear and nonlinear algebraic equations. The method of finding a solution to the model is discussed, and results of calculations for turbine overspeed and sudden increase in inlet pressure are given. (ERA citation 10:030816)
