Gas turbine plants play important role in power production whenever there has been scarcity of power generated from conventional
sources like oil or gas. Researchers have been trying to simulate this kind
of power plants for higher outputs with improved system efficiency. In
this scenario, present work attempts to study and simulate a closed cycle
gas turbine power plant for different configurations. All the components
are modelled and integrated to form a power generating and heating
system. Parameters like compressor inlet pressure, pressure ratio and
turbine inlet temperature are varied. Performance curves of the individual components and the integrated system are plotted and studied.
Results obtained show the significance of pressure ratio and turbine
inlet temperature. Utilization of heat from turbine exhaust shows the
possibility of a cogeneration bottoming cycle that can be used for district
heating, refrigeration and air conditioning applications. Also, it is found
that inlet pressure of 1 bar allows both topping and bottoming cogeneration cycles to perform optimally.
