In order to describe the performance of a cogeneration system it is necessary to determine various thermodynamic parameters. These thermodynamic parameters can be useful in determining the merits and economics of cogeneration systems. These parameters can be determined by measurements or by computer modeling of a given cogeneration system. In an earlier study, the performance of this plant was analysed using a computer program. In this paper, results from an extensively modified computer program are compared to a set of plant measurements. The measurements are taken under actual operating conditions. This type of comparison is necessary if accurate calculations of performance and return on investment are to be made. Large inaccuracies in such predictions often occur. It should be noted that the economics and performance of cogeneration systems are complex and involve far more than the thermodynamic parameters considered here.
