Abstract :
Investigations on large turbogenerator shaft torques caused by different types of electrical disturbances have shown that the stress levels can be higher than during conventional terminal short circuits. Shaft-stress trend in the future highly utilized generators is illustrated. Influence of electrical and mechanical modeling on the calculation results is studied. A suitable protection conception is outlined.
