METHOD FOR CONTROLLING THE COOLING AIR MASS FLOWS OF A GAS TURBINE GROUP

摘要

The invention relates to a method for controlling the cooling air volume of a gas turbine group (1, 2, 3). Appropriate means (32, 33) are provided inside the cooling system (26, 27) that enable the cooling air volume to be varied. These means are controlled on the basis of an operating parameter (X). This operating parameter is determined in an arithmetic unit (22) by appropriately combining measured machine data (p1, p2).
