THYRISTOR CONTROL OF LOCOMOTIVES AND ITS INTERFERENCE ON DATA TRANSMISSION

The practically inertialess thyristor controls the tractive power of locomotives very efficiently but this type of phase angle control produces a severe harmonic distortion of the contact wire current. The higher order harmonics interfere with the communication signals in the adjacent telecommunication lines. Measurements were made to determine the impairment of data transmission comprehensive. After a brief review of thyristor control, the test condition and the program of measurement are discussed. The method of evaluation, which is outlined in this paper consists of two stages: an exploratory stage, where the currents and voltages are compared with each other and the final stage, the probability of bit error with different types of modulation are assessed.
