| Summary: | This study deals with modelling and performance enhancements of a combined cycle
power plant. Several configurations of CCGT power plants are proposed by thermal
analysis. The
integrated model and simulation code for exploiting the performance of
the
CCGT power plant is developed utili
zing MATLAB code.
A different strategy for
the
CCGT power plant's operational modelling is suggested for power plant operation,
to improve overall performance.
The effect of is
e
ntropic efficiencies on the performance
of the CCGT power plant
is
based on rea
l CCGT power plants.
An extensive
thermodynamic analysis of the modifications of the most common configuration
enhancements has been carried out. The simulati
o
n results
for
the HRSG configurations
show that the maximum power output (1000
MW) occurred in th
e supplementary triple
-
pressure reheat CCGT at high isentropic compressor efficiency. Furthermore,
with the
triple
-
pressure reheat CCGT and higher isentropic turbine efficiency the maximum
overall efficiency was about 58.3%.
In addition, the proposed CCGT
system improved
the
thermal efficiency
by 1.6%
and
the power output by
11.2%.
Thus, the isentropic
efficiencies and CCGT configurations
have a
strong influence on the overall
performance of the CCGT |
