ABSTRACT: The represent paper will study the performance of the
power plant with the combination of dry and wet cooling systems in different
operating conditions. A thermodynamic performance analysis of the steam cycle
system was performed by means of a program code dedicated to power plant modeling
in design operating condition. Then the off-design behavior was studied by
varying not only the ambient temperature and relative humidity but also several
parameters connected to the cooling performance, like the exhaust steam flow
rate, the air cooling fan load and the number of operating cooling water pumps
and cooling towers. The result is an optimum set of variables allowing the dry
and wet cooling system be regulated in such a way that the maximum power is
achieved and low water consumption.
