Method of calculations of current harmonics in a current taken from 3kV DC network by a traction vehicle with asynchronous drive

Introduction of modern traction vehicles with converter drives makes a need of undertaking analysi of electromagnetic compatibility. There is presented in the paper a method of calculation of the selected harmonics in catenary resulted from distorted voltage supplying asynchronous motors. The first type Bessel functions have been applied for discription of voltage supplying traction motors.Introduction of modern traction vehicles with converter drives makes a need of undertaking analysi of electromagnetic compatibility.

Wprowadzenie nowoczesnych pojazdów trakcyjnych z napędem przekształtnikowym wprowadza konieczność prowadzenia analiz zjawisk dotyczących kompatybilności elektromagnetycznej. W artykule zaprezentowana została metoda obliczenia wybranych harmonicznych w sieci trakcyjnej wywołanych odkształconym napięciem zasilania silników asynchronicznych. Do opisu napięcia zasilania silnika zastosowano funkcje Bessela pierwszego rodzaju.
