Modelling of cogeneration units for energetic balance

This article deals with general modelling of cogeneration units. It provides substantial information about cogeneration units. Development of cogeneration units has experienced an evident boom over the recent years. These are significant sources of both heat and electric power. That is the reason for seeking the fastest and the cheapest method to design a cogeneration unit with optimal performance. The fastest and still the cheapest method is modelling, as desribed by this article. It shows a model of a cogeneration unit with the electric power of 140kWe and the heating power of 207kWt (140kWe/207kWt).
