| Abstract: | Modelling power plants using real process data is crucial in determining the cost-effectiveness and flexibility of systems. The quality of the elaborated model is determined with the validation of the model, which can also give results for the operating regimes of the plant, which are not often used in practice. In this way, also the operation and responsiveness of power plants outside the range of planned operation are determined. The model simulates the operation of a diesel engine (DE) required to start a combined heat & power plant (CHPP) from a black-out or loss of the electrical power network supply. The model is made on the basis of data provided by the manufacturer and the measured DE data. The results of the model enable detailed insight into the characteristics of the DE behaviour at different operating regimes. The economic and ecological rationale ranges of operation of the DE can be determined from the characteristics of operation. The results of the model show that the DE operates with a 41.72% average efficiency, consumes from 0.114 kg/s of diesel fuel for its operation and up to 3.68 kg/s of air, the air ratio ranges from 2.2 to 2.5. DE develops shaft power up to 2170 kW. |
