N2 - This article describes the validation of a supercritical steam cycle. The
cycle model was created with the commercial program GateCycle and
validated using in-house code of the Institute of Power Engineering and
Turbomachinery. The Institute's in-house code has been used extensively
for industrial power plants calculations with good results. In the first
step of the validation process, assumptions were made about the live steam
temperature and pressure, net power, characteristic quantities for high-
and low-pressure regenerative heat exchangers and pressure losses in heat
exchangers. These assumptions were then used to develop a steam cycle
model in Gate-Cycle and a model based on the code developed in-house at
the Institute of Power Engineering and Turbomachinery. Properties, such as
thermodynamic parameters at characteristic points of the steam cycle, net
power values and efficiencies, heat provided to the steam cycle and heat
taken from the steam cycle, were compared. The last step of the analysis
was calculation of relative errors of compared values. The method used for
relative error calculations is presented in the paper. The assigned
relative errors are very slight, generally not exceeding 0.1%. Based on
our analysis, it can be concluded that using the GateCycle software for
calculations of supercritical power plants is possible.
