Ensuring the efficient operation of a combined-cycle gas plant in the warm season

Abstract

Abstract Summer technological restrictions on the electric power generation by the power stations have a significant impact on the economic indicators of generating companies. These restrictions are associated with the deterioration of performance of the generating and auxiliary equipment of stations at high air temperature and due to the following factors: the progressive decrease of electric power of gas turbines with increasing outside temperature above the calculated one (+15 °C); the rise of the water temperature in the cooling systems of main and auxiliary equipment and, as a result, the deterioration of the vacuum in the condensers of steam turbines and the operation of the cooled equipment in more intense thermal conditions.
