Simulation of a thermal power plant with district heating: Comparative results of 5 different codes

摘要: This paper presents a simulation code for the thermal power plant AVV1, located in Copenhagen, Denmark, response to challenge launched at ECOS 2003 congress. The program was specially created this contest, including calculation of thermodynamic properties water, as based on IAPWS97. Every component is modeled through mass and energy balance equations, solution whole system achieved by successive substitution scheme. simulated two operation modes: generating electricity only, district heating simultaneously. In first mode, four series simulations are run loads varying from 40% 100%. Each assumes different hypotheses with respect variation isentropic efficiencies pressures groups that form turbine. second 100% load. An exergetic analysis plant, modes analyzed, presented. generated results compared those presented several researchers who have tackled problem. comparison shows here agree most satisfactorily literature.
