Research on Coordinated Control System of Unit Considering Regenerator System Based on Bilinear Fit

Abstract:

The validity of mathematical model direct impact the research result of the boiler-turbine coordinated control system. 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 mathematical model of boiler-turbine coordinated system has been modified and supplied by bilinear fit. And, for the practical problems that need to be resolved in research work of the coordination controlled object’s mathematical model, the mathematical analysis was carried out by the regenerator system integrated into heat balance of generator unit and a new type of simulation mathematical model of coordinated control system with regenerator system was researched. The mathematical model was verified through the simulation test. Based on the thought that dynamic energy and static energy separation, the of intelligent controller is structured and applied in coordination control system of generator unit. Simulation results show that not only load response and anti-interference ability are improved, but also dynamic overshoot greatly reduces
