Przedstawiono analizę impedancji z pełnego przejazdu lokomotywą przekształtnikową dla wybranych częstotliwości w aspekcie zakłóceń w sieci trakcyjnej – dla przykładowego filtra wejściowego.
The article presents the methods of determination and analysis of the continuance of harmonics in the supply current of a modern subway vehicle with an asynchronous converter power. Knowledge of the harmonic content of the supply current is a very important part of the study, allowing the vehicle to operate. In order to determine the harmonic voltages and currents, a computer model of the test vehicle...
In order to build a tram-train transport system, it is necessary to have a rail vehicle capable of running off both 3300Vdc railway electric overhead lines and 600Vdc tramway overhead lines. One of the solutions would be to build a high voltage reducing converter. This article presents a design of a resonance converter with a toroidal transformer and discusses results of laboratory tests carried out...
Analytical model of 3 phase converter traction drive with 2 drive unit supplied from 3 kV DC line is analyzed. The harmonics generated by the converter system injected into the supplying line are determined in analytical way. The calculation method is based at the generalized theory of static converter. The calculation results achieved in that way are compared with the measuring made in traction drive...
Analytical model of 3 phase converter traction drive with 2 drive unit supplied from 3 kV DC line is analyzed. The harmonics generated by the converter system injected into the supplying line are determined in analytical way. The calculation method is based at the generalized theory of static converter described in the literature [3,4,5,6,7,8]. The calculation results achieved in that way are compared...
