【Abstract】 A three-input two-output dynamic model was established for a steam generator,based on mechanism analysis of the generator using the method of partition combined with lumped parameters.The mechanism model was then transformed into a nonlinear dynamic one based on state space,with which numerical simulations were conducted,thus to provide a relatively complete way of model building and treatment.Results show that the model developed has a complete structure,with high accuracy,agreeing well with theoretical analysis,which is helpful for further study on water level control of steam generators.更多还原
