Abstract

The high harmonics of voltage and current that are generated by traction transformers mounted on ac electric rolling stock have a negative influence on systems of electrical power distribution and their components. The exact interrelation between harmonics and losses is too complicated to generalize, and, therefore, the influence of the form of current and voltage is determined as a rule using the power factor. The fundamental disadvantage of ac electric locomotives is a low power factor. To improving energy indices, methods were developed that make it possible to increase the power factor. The effectiveness of the proposed methods as a rule is estimated by means of determining the power factor. A calculating algorithm for the power factor is proposed in this work, which takes into account the influence of distortion power.

Keywords: electric locomotive of single-phase alternating current power factor energy effectiveness rectifier–inverter transformer
