Abstract
A finite element technique and computer code
for the numerical analysis of 3D transient electromagnetic
fields and temperature distribution due to negative sequence
currents in large synchronous turbogenerator rotors are
developed. Electromagnetic-thermal phenomena in a 300 MVA
class turbogenerator rotor during a line-to-line short circuit on
two phases of the machine are numerically investigated. Effect
of the various conditions of the rotor cooling on its thermal
state is studied. Numerical results obtained can be used for the
computer simulation of the thermo-mechanical behaviour of
the rotor.
