The General Rules Of Reversed Modeling Method And Its Application

In consideration of nonlinear and multiple coupling characteristics of thermal system in large capacity of power plant,the research on reversed modeling technology and its application with operation data of power plant is presented.The modeling process and data processing technology,data modeling,model and algorithm are included.The intensive studies are as following.And a deep research of two contents.Firstly,the partial least-square regression algorithm is applied to modeling for and plant heat consumption rate of the power plant in economic aspect,and for a predictive regression correlation analysis.Secondly,the time series of the algorithm is applied to modeling and analysis of the coal water ratio.Research results show that the reversed modeling method can be helpful for the thermal system modeling.And the new idea can be used as complement of mechanism modeling of system,and can inspect or verify with each other.
