Resumen

AGUILAR-ALDERETE, R.; SANCHEZ-SILVA, F.  y  CARVAJAL-MARISCAL, I.. Modeling and dynamic simulation of an air cooled steam condenser in a combined cycle power plant. Rev. Mex. Ing. Quím [online]. 2015, vol.14, n.3, pp.767-780. ISSN 1665-2738.

The behavior of an air-cooled steam condenser (ACSC), installed in a Combined Cycle Gas Turbine (CCGT), has been analyzed under various operation conditions and disturbances in this paper. The analysis has been carried out by using a dynamic simulation technique, dividing the equipment in modules and applying conservation laws of mass and energy to each one. The solution of the resulting set of equations for one module was gotten by implementing a simulation model using a software named Sirnulink. Some parameters included in the set of equations were adjusted by using steady state data from the plant. Coupling the modules, an integral program was created to simulate the ACSC's performance under different values of ambient air temperature, steam ma^ flow rate and cooling air mass flow rate. Some disturbances were also simulated to analyze the dynamic response of the model. Model response was compared versus power plant data as model validation. It was found it is more accurate for operation conditions close to the design values and its dynamic response is acceptable.

Palabras llave : mathematical modelling; dynamic simulation; air cooled steam condenser; simulink; combined cycle.
