Mixed Boiler-turbine Coordinated Control System Mathematical Model Based on Mechanism Modelling and Parameter Identification

摘要

Based on the excellence of mechanism mathematical model and system identification model, this paper established a mixed model of boiler-turbine coordinated control system (CCS), which combines mechanism analysis and parameter identification. To configure the model into a distributed control system (DCS) of the unit generator, by comparing the model parameters trend curve with the unit generator actual parameters trend curve during the same period, result can be obtained that the modelling method given by this paper is correct and exact. In addition, this paper also first time gives the method of checking mathematical model correctness and accuracy, and engineering practice shows that this method is simple and effective
