Application of Bilinear Fit to Non-linear Mathematical Model of Generator Unit

摘要：

In this paper, applying the mechanical modeling method to set up model of boiler-turbine coordinated control system, and obtain its parameter by parameter identification, the model is proved effectively through practical application. For steam flow, we fit it for bilinear function of valve opening and turbine throttle pressure by making use of generalized least squares inverse, the mathematical model of nonlinear boilerturbine coordinated system has been modified and supplied by the method, and simulation analysis has been made on it. The study shows that: the model can more accurately reflect the dynamic characteristic of steam flow under various operating condition, through the simulation test, the modified nonlinear mathematic model of unit it is proved effective and accurate.
