An Adaptive Control System for Steam Temperature of Fossil-Fuel-Fired Thermal Power Plant

Abstract This paper introduces some extention of the studies reported by M. Uchida and two of the present authors at the IFAC Symposiums on Design Methods of Control Systems and on Control of Power Plants and Power Systems(Uchida, M. and others, 1991, 1992). In this paper, the concept of the proposed system identification method and the simulation-model-based control method is briefly explained. Then, the applications of the method to the power plant are introduced with the results of simulation studies. The subjects discussed in the paper is the steam temperature control of the superheater outlet of the power plant and the mainsteam temperature raising control at the start-up stage of the power plant. The simulation results verifying the effectiveness of the proposed method are introduced for both of the above applications.
