In this paper the thermal cycle model of supercritical power plant conjugated with the cooling system working at different operating conditions was presented. The calculations for reference unit of 600 MW output with close cooling system were made. The basic parameters and construction type of cooling tower and condenser were assumed. The algorithm for cooling system consists of the cooling tower model and condenser model was presented. The iteration process to calculate the parameters of thermal cycle and cooling water cycle was described. The influence of atmospheric temperature changes typical for the one-year period on the power plant performance indicators was discussed. The results were presented and the investigations were summed up.
