Excitation system of asynchronized turbogenerators

Dovganyuk, I. Ya. / Plotnikova, T. V. / Sokur, P. V.

Abstract In contrast to conventional synchronous turbogenerators, an asynchronized turbogenerator can operate for a long time with a disabled excitation system and short-circuited longitudinal-lateral rotor windings, which increases substantially the operational reliability. The requirements on the power and information equipment of the excitation system with respect to redundancy are also less strict. Computer simulation of emergency conditions in an asynchronized turbogenerator has made it possible to substantiate the requirements on the speed of response to current reversal in the excitation system and to recommend an algorithm for protection performance upon transition of the turbogenerator to the standby mode.
