Abstract. In the article considers the calculation of the modes of occurrence of subharmonic components in traction power supply networks of railway transport, containing traction converters, controlled and uncontrolled rectifiers. The processes of the occurrence of harmonic components during the operation of electric locomotives with zone-phase and pulse control using a four-quadrant 4q-S converter in power circuits are considered, harmonics related to the main and subharmonic components are determined by the harmonic balance method.
Keywords: subharmonics, zone-phase control, pulse control, harmonic balance, four-quadrant 4q-S converter.
