The evaluation of the new generation of gas turbines is complicated and presents new problems, which have to be addressed. The
complete unit will give the required performance when running at the design point (base load performance); that is, when it is
running at the particular speed, pressure ratio and mass flow for which the components were designed. The problem then remains
to find the variation of performance of the gas turbine over the complete operating range of speed and power output, i.e. part load
performance. In practice it is found that the gas turbine operates at various load as per the requirement of power and process
steam in a cogeneration mode. So it is necessary to analyze the off-design performance of the gas turbine in cogeneration mode.
The on line monitoring of the gas turbine performance is important for the plant engineers to achieve their goals of maintaining
high availability of the machinery, minimizing degradation and maintaining operation near design efficiencies. Present work is
related the off design performance assessment of the single shaft gas turbine in cogeneration cycle mode.
