Підвищення ефективності тягового електропривода трамвая КТ4-СУ

Abstract

According to the results of research, a new way of solving the problem of pulse-width control of the power converter, which serves to power the DC motor of sequential excitation of the tram, is proposed. The computer simulation compares three methods of calculating the regulators of the system "pulse-width converter - DC motor". In a DC electric drive with a pulse-width method of controlling the supply voltage of the motor, the calculation of the control system causes difficulties. These difficulties are due to the pulse nature of the power converter, as well as the fact that the motor uses a serial or mixed excitation motor. For the given conditions of work of the tram parameters of the electric drive are also calculated, the basic elements are chosen and technical and economic comparison of existing variants of realization is executed.
