Two Kinds of Practical Modified Lumped Parameter Dynamical Models of Uniphase Heated Tubes

FANG Yong sheng 1, SHUI Zhe 1, JIANG Xue zhi 1, LU Chong de 1, CHEN Lai jiu (1.Dept. of Thermal Engrg., Qinghua Univ., Beijing 100084, China; 2. Dept. of Power Engrg., Southest Univ., Nanjing 210018, China)  
Two kinds of lumped parameter dynamical models most used for boiler uniphase heated tubes are modified by inertia compensation, and so two kinds of high precision modified lumped parameter dynamical models are developed in this paper. All of the modified models can sufficiently reflect the distributed parameter characteristic of thermal systems, and can also apply to research on both full scale high precision real time simulation training system and full scale control system simulation of power plants. Every modified model has the advantage that modelling is simple, computing is convenient and practicability is strong, and so it can be widely applied to engineering. Figs 6 and refs 5.
