| Abstract: | The dynamic simulation model for each cooling unit's condensation heat transfer and for condenser's pressure calculation were established in application of project blocking method by full considering the effect of condenser's structural parameters and work mass's physics parameters on heat-transfer process.Algorithms were developed with module modeling method based on the STAR-90 simulation support system.The global simulation model for one condenser system of a 200 MW direct air-cooled unit was created.The model's static simulation precision under different loads and its dynamic response to various disturbances were tested,which indicated the model can meet engineering requirements. |
