Ограничение резонансных токов при испытаниях электроприводов постоянного тока в системе генератор–двигатель

Abstract

The Possibility of the resonance currents limitation in the loading system on the basis of direct-current is shown. The generator works in the self-oscillating mode by introduction of additional resistance in the parallel excitation winding of the generator. The effective current - frequency of resistance commutation dependence was resulted during mathematical modeling. The questions of additional resistance commutation are considered taking into account a change of the time constant of the parallel excitation winding of the generator.
