摘要
Abstract
So far,in most studies,the supercritical unit is simply modeled in the form of transfer function matrix,from which the dynamic characteristics of other internal parameters cannot be observed.In this paper,the simplified nonlinear model of a 600-MW supercritical unit is established with the combination of mechanism analysis and parameter identification method.The dynamic and static parameters of the model are determined based on the data obtained from load variation test of one 600-MW "W" flame supercritical once-through boiler unit.Comparison between the Simulink simulation results and actual operation curves shows that the new model reflects the nonlinear dynamic characteristics of the unit well and can be used to study the coordinated control strategy and dynamic characteristic analysis for the supercritical units with "W" flame furnace.By modifying some parameters,the model can be used for research on other related aspects of supercritical units as well.关键词
