The simulator contest proposed for the ECOS 2003 conference has been solved using the DNA energy system simulator. The contest concerns the steam process of the Avedøreværket Unit 1 (AVV1) power plant. The plant is a 250 MWCHP plant with a maximum district heat production of 330 MJ/s. The plant has a net electric efficiency of 42% and a maximum energy utilization of 92%. In this paper it is demonstrated, that the DNA model of AVV1 can calculate the whole flow sheet balance at any load point, i.e., any possible combination of power production and district heat production. The paper also contains a brief description of the DNA simulator, as well as a short notice on some of the component models used. In particular, there is a small investigation of the difference obtained in the solution depending on the model used for the turbine (isentropic efficiency, polytropic efficiency, or straight-line expansion).
