Abstract
A method for controlling the loadability of high speed air-cooled turbo-alternators (10), in which the rotor winding has an intensive direct conductor cooling, and when the load increases, the pressure of the cooling air is increased at most up to 2 bar abs., while with decreasing load said pressure is decreased till the atmospheric value is reached and during the pressure adjustment the temperature of the rotor winding is kept substantially unchanged. An arrangement for carrying out the method comprises an air- recirculating cooling system (11, 12, 13, 14) and an air supply means (17) with a compressor (22, 23) and an air tank (20) and in the arrangement a pressure adjusting means (18 and 19) is provided capable of continuously changing the pressure in the interior within a range of about 1.01 and 2 bar abs. <IMAGE>
